我国是世界上生态环境恶化最严重的国家之一,生态环境恶化的种种表现可归咎于三大原因:一是水土生态恶化,二是环境污染,三是资源衰竭。水土生态保持认为植被与水土是相互联系不可分割的有机统一体,水土生态恶化是最大的生态环境恶化,抓住了水土生态保持这个关键,也就占领了生态保护和生态建设的制高点。依据水土生态的内涵,对我国水土生态保持宏观管理提出了一些建议。
China is one of the countries with the most serious deterioration of the ecological environment in the world. The deterioration of the ecological environment can be attributed to three major causes: First, deterioration of soil and water ecology; second, environmental pollution; third, depletion of resources. Soil and water conservation maintains that vegetation and water and soil are interconnected and indivisible organic reunification. The deterioration of soil and water ecology is the greatest deterioration of the ecological environment. It seizes the key point of water and soil ecology preservation and occupies the commanding point of ecological protection and ecological construction. Based on the connotation of soil and water ecology, some suggestions are put forward to maintain macroscopic management of soil and water ecology in China.
