  2022年7月,國家生態環境部黃潤秋在會議中強調,要深刻把握“十四五”水生態環境保護的總體策略,不斷推進水生態環境保護事業向前發展。一是更加突出服務大局,統籌做好疫情防控、經濟社會發展和生態環境保護,推動實現更高質量、更有效率、更加公平、更可持續、更為安全的發展。二是更加突出人民至上,努力提供更多優質水生態產品、創造更多更好親水空間,讓工作成效體現在人民群眾直觀感受上。三是更加突出穩中求進,將工作重心放在夯實基礎、**質效上,力爭在若干難點和關鍵環節上實現突破。四是更加突出“三水統籌”,著力推動水生態環境保護向水資源、水生態、水環境等流域要素系統治理、統籌推進轉變。五是更加突出精準、科學、依法治污,錨定精準治污的要害、夯實科學治污的基礎、增強依法治污的保障。至此,我們一起來了解一下水生態環境治理方法有哪些?我國常用的水生態修復治理措施有哪些!

水生態環境修復治理

  生態治理法:水生態技術就是通過一系列措施,將已經退化或損壞的水體生態系統恢復、修復、并成百上千倍的強化其納污能力,使水體保持長久清澈與穩定。水生態技術是以立足長遠的循環經濟,打造長治久安的生物食物鏈體系。目前真正行之有效的水體生態系統尚非常之少,均停留于概念階段。

  水土保持生態修復的技術方法

  (1)退化坡面生態系統生態修復

  退化耕地生態系統的生態修復:少施化肥,增施農家肥料;種植綠肥植物,增加固氮作物品種;輪作、套作,間種、混種;減少化學防治,增加生物防治;植等高植物籬等。退化林地、草地、荒地生態系統的生態修復:在封禁的基礎上,補種鄉土樹種、草種。封禁時間的長短因生態系統類型、受損程度、氣候等因素的不同而不同,一般來說,喬木林、灌木林、草地生態系統可分別為8年以上、5~8年、3~5年。

  (2)退化河流生態系統生態修復

  在土壤侵蝕地區,導致河流退化的驅動力主要有修路、開礦、樵采、河岸放牧、化肥與農藥的面源污染、工業廢水與生活污水的點源污染、過度捕魚等,對由于這些驅動力所導致的退化河流生態系統進行生態修復,*重要的是要減輕或解除導致河流生態系統退化的驅動力,讓河流休養生息。

  (3)內陸河流域退化綠洲生態系統生態修復

  合理開發利用水資源,實施生態應急補水工程,至少要滿足天然綠洲生態系統*小生態需水量;合理調整土地利用結構,適當減少人工綠洲面積,使人工綠洲和天然綠洲面積比例調整到1:1左右。

  (4)退化水庫生態系統生態修復

  對退化水庫生態系統的生態修復可采取與退化河流生態系統相同的方法。

  (5)退化礦山生態系統生態修復

  該生態系統的土壤、植物等組分完全受損,缺乏植物生長所需要的營養元素,對這種嚴重退化的生態進行生態修復,可采取的方法有:覆蓋土壤,對土壤進行物理處理,添加營養物質,去除有害物質,種植適應性強的先鋒樹種或草種、間種鄉土樹種或草種。

  水土保持生態修復的技術方法

  (1)生態自然修復的基本技術方法是封禁法。該方法適用于受損程度較輕的生態系統。

  (2)自然和人工共同修復生態的基本技術方法是“封禁+補種”法。該方法適用于受損程度較重的生態系統。

  水土保持是土壤侵蝕地區經濟社會可持續發展的生命線,是生態環境建設的主體。水土保持生態修復的提出與實施是水土保持工作理念的重大創新,但水土保持生態修復不應局限于當前的狹義水土保持生態修復,應從狹義水土保持生態修復向廣義水土保持生態修復轉變。即使實現了這樣的轉變,水土保持生態修復也只是水土保持流域綜合治理的一個重要方面,它不能完全替代人工造林種草等水土保持生物措施,更不能替代坡改梯、淤地壩、谷坊、小型水庫、蓄水池等水土保持工程措施。

  常用的水生態治理的方法有:(1)減少和消除污染物排放的廢水量;(2)全面規劃,合理布局,進行區域性綜合治理等等。

  生態環境治理盡量根據生態文明建設基本建設基建項目的核心理念和要求來確立其辦事標準。在生態文明建設深化改革整體方案中明確指出:“以基建項目美好家園為目標,以妥善處置人類與環境關系為重要,以解決綠色生態生態環境保護領域顯出難點為主導性,保證 國家生態安全,改善生態環境保護,提高資源使用率,推動造成人類與環境和諧發展趨向的現代化建設機遇與挑戰。” 那麼,生態環境治理整治的具體辦法有什么?

  生態環境治理有五條防范措施,**是生態紅線的區劃。第二是合理的區域發展合理布局。第三是地域土壤資源運用方向和布局調整的調整,造成農、林、草、漠、澤、水與大都市、城市交通、廠礦企業正中間的合理布局。這三條是必要條件。第四是以維護保養首先選擇,充裕高度重視自然規律,充分運用自然恢復的發展前景,封山育林、育沙育草、保濕補水。第五是自然恢復與人力修復緊密聯系。

  我們要塑造六大核心理念,即塑造尊重自然、順應自然、保護自然的核心理念;塑造發展趨向和維護保養相統一的核心理念;塑造綠水青山就是翠綠色發展戰略的核心理念;塑造自然實用價值和自然財產的核心理念;塑造室內空間設計均衡的核心理念;塑造青山綠水林田湖草是一個生命共同體的核心理念。

  生態環境治理針對顯出的生態問題付諸實踐,是便于保證 生態安全,促進人和自然的和諧;生態環境治理要鍥而不舍節約首先選擇、維護保養首先選擇、自然恢復核心的指導方針。在《加快推進生態文明建設的意見》中,又技術專業再加了“在生態文明建設基本建設和修復中以自然修復核心,與人力修復緊密聯系”那般較為多方位的詮釋,現實意義長久。

  生態環境治理要為自然資本利得,多方位** 綠色生態管理體系的服務功效;要維修保養好青山綠水林田湖草這一生命共同體,按照系統論的觀念進行環境衛生整治。

  根據治理總體目標的具體情況,分別選用有針對性的人力治理防范措施。如植綠護綠、植樹、人力促進還林升級,林下或林隙引入混交綠色植物、照料管理方案(修枝、除蘗、割灌、間伐、補栽或補播、土地復墾);必不可少時的合理采伐升級;必不可少的建筑項目防范措施,如生態環境保護防范措施(翻地、修田園風光、治溝等),設置工業設備沙障防風固沙等;再加上蟲害鼠害防止及消防安全防范措施。

  In July 2022, Huang Runqiu of the Ministry of ecology and environment stressed at the meeting that we should deeply grasp the overall strategy of water ecological environment protection during the "14th five year plan" and constantly promote the development of water ecological environment protection. First, we should give more prominence to serving the overall situation, coordinate epidemic prevention and control, economic and social development and ecological environment protection, and promote higher quality, more efficient, fairer, more sustainable and safer development. Second, we should put people first, strive to provide more high-quality aquatic ecological products and create more and better hydrophilic space, so that the work results can be reflected in the intuitive feelings of the people. Third, we should pay more attention to seeking progress while maintaining stability, focus on consolidating the foundation and improving quality and efficiency, and strive to achieve breakthroughs in a number of difficulties and key links. Fourth, we should give more prominence to the "overall planning of three water resources" and strive to promote the transformation of water ecological environment protection to the systematic governance and overall promotion of river basin elements such as water resources, water ecology and water environment. Fifth, we should give more prominence to precise, scientific and legal pollution control, anchor the key of precise pollution control, consolidate the foundation of scientific pollution control, and enhance the guarantee of legal pollution control. So far, let's learn about the methods of ecological environment treatment in Yishui? What are the commonly used water ecological restoration and treatment measures in China!

  Ecological treatment method: water ecological technology is to restore and repair the degraded or damaged water ecosystem through a series of measures, and strengthen its pollution carrying capacity hundreds of times, so as to keep the water clear and stable for a long time. Water ecological technology is based on long-term circular economy to create a long-term biological food chain system. At present, there are very few truly effective water ecosystems, which are still in the conceptual stage.

  Technical methods of soil and water conservation and ecological restoration

  (1) Ecological restoration of degraded slope ecosystem

  Ecological restoration of degraded farmland ecosystem: less chemical fertilizer and more farmyard fertilizer; Planting green manure plants and increasing varieties of nitrogen fixing crops; Rotation, intercropping, intercropping, mixed planting; Reduce chemical control and increase biological control; Plant contour hedgerows, etc. Ecological restoration of degraded forest land, grassland and wasteland ecosystems: replant native tree species and grass species on the basis of closure. The length of closure varies with the type of ecosystem, damage degree, climate and other factors. Generally speaking, arbor forest, shrub forest and grassland ecosystem can be more than 8 years, 5 ~ 8 years and 3 ~ 5 years respectively.

  (2) Ecological restoration of degraded river ecosystem

  In soil erosion areas, the driving forces leading to river degradation mainly include road construction, mining, woodcutting, bank grazing, non-point source pollution of chemical fertilizers and pesticides, point source pollution of industrial wastewater and domestic sewage, overfishing, etc. to carry out ecological restoration of degraded river ecosystems caused by these driving forces, the most important thing is to reduce or remove the driving forces leading to river ecosystem degradation and let the river recuperate.

  (3) Ecological restoration of degraded oasis ecosystem in inland river basin

  The rational development and utilization of water resources and the implementation of ecological emergency water replenishment projects should at least meet the minimum ecological water demand of the natural oasis ecosystem; Reasonably adjust the land use structure, appropriately reduce the area of artificial oases, and adjust the area ratio of artificial oases to natural oases to about 1:1.

  (4) Ecological restoration of degraded reservoir ecosystem

  The ecological restoration of degraded reservoir ecosystem can adopt the same method as that of degraded river ecosystem.

  (5) Ecological restoration of degraded mine ecosystem

  The soil, plants and other components of the ecosystem are completely damaged and lack of nutritional elements required for plant growth. The ecological restoration of this seriously degraded ecosystem can be carried out by covering the soil, physically treating the soil, adding nutrients, removing harmful substances, planting pioneer tree species or grass seeds with strong adaptability, and intercropping native tree species or grass seeds.

  Technical methods for ecological restoration of soil and water conservation in a narrow sense

  (1) The basic technical method of ecological natural restoration is the closure method. This method is suitable for ecosystems with less damage.

  (2) The basic technical method of natural and artificial ecological restoration is the "closure + replanting" method. This method is suitable for ecosystems with heavy damage.

  Soil and water conservation is the lifeline of sustainable economic and social development in soil erosion areas and the main body of ecological environment construction. The proposal and implementation of soil and water conservation ecological restoration is a major innovation in the concept of soil and water conservation, but the ecological restoration of soil and water conservation should not be limited to the current narrow sense of soil and water conservation ecological restoration, and should be transformed from the narrow sense of soil and Water Conservation Ecological restoration to the broad sense of soil and water conservation ecological restoration. Even if such a transformation is achieved, the ecological restoration of water and soil conservation is only an important aspect of the comprehensive management of water and soil conservation basins. It can not completely replace the biological measures of water and soil conservation such as artificial afforestation and grass planting, nor can it replace the engineering measures of water and soil conservation such as slope to terrace, silt dam, Gufang, small reservoir, water storage tank, etc.

  The commonly used methods of water ecological treatment are: (1) reduce and eliminate the amount of waste water discharged by pollutants; (2) Comprehensive planning, rational layout, regional comprehensive management, etc.

  Ecological environment governance should try to establish its standards according to the core concepts and requirements of ecological civilization construction capital construction projects. In the overall plan for deepening the reform of the construction of ecological civilization, it is clearly pointed out that "the goal is to build a better home for infrastructure projects, the importance is to properly handle the relationship between human beings and the environment, and the main guidance is to solve the difficulties in the field of green ecological and environmental protection, so as to ensure national ecological security, improve ecological and environmental protection, improve the utilization rate of resources, and promote the opportunities and challenges of modernization that lead to the harmonious development trend of human beings and the environment." So, what are the specific measures for ecological environment governance?

  There are five preventive measures for ecological environment governance. The first is the zoning of ecological red line. The second is reasonable regional development and reasonable layout. The third is the adjustment of the use direction and layout of regional soil resources, resulting in a reasonable layout between agriculture, forestry, grass, desert, Ze, water and metropolis, urban transportation, factories and mining enterprises. These three conditions are necessary. The fourth is to choose maintenance first, attach great importance to the natural law, and make full use of the development prospect of natural recovery to close mountains for afforestation, sand and grass cultivation, moisture and water replenishment. Fifth, natural restoration is closely related to human repair.

  We should shape six core concepts, namely, the core concepts of respecting nature, conforming to nature and protecting nature; Shaping the core concept of the unity of development trend and maintenance; Shaping green waters and mountains is the core concept of green development strategy; The core idea of shaping natural practical value and natural property; Shaping the core concept of indoor space design balance; Shaping green mountains, green waters, forests, fields, lakes and grasses is the core concept of a community of life.

  The practice of eco-environmental governance in response to emerging ecological problems is conducive to ensuring ecological security and promoting the harmony between man and nature; We should persevere in the ecological environment governance, which is the core guideline of saving first, maintenance first, and natural restoration. In the opinions on accelerating the construction of ecological civilization, the technical major added a more comprehensive interpretation of "taking natural restoration as the core in the basic construction and restoration of ecological civilization construction and closely linked with human restoration", which has a long-term practical significance.

  Ecological environment governance should benefit natural capital and improve the service efficiency of the green ecological management system in multiple directions; We should maintain the life community of green mountains, green waters, forests, fields, lakes and grasses, and carry out environmental sanitation renovation according to the concept of system theory.

  According to the specific situation of the overall goal of governance, select targeted human governance preventive measures respectively. Such as greening, tree planting, human promotion of forest upgrading, introduction of mixed green plants under the forest or gaps, care and management schemes (pruning, tillering, cutting and irrigation, thinning, replanting or reseeding, land reclamation); Reasonable cutting and upgrading when necessary; Necessary preventive measures for construction projects, such as ecological environment protection measures (land reclamation, rural scenery, ditch management, etc.), setting up industrial equipment sand barriers to prevent wind and fix sand, etc; In addition, pest and rodent prevention and fire safety precautions.

  The above is the understanding of Ruizhe environmental protection about [water ecological restoration and treatment measures and methods].
