- 摘要:
- 二龙湖流域面积3 676.00 km2，其中水土流失面积达1 453.72 km2，建库50多年间流入二龙山水库库区泥沙总量10 101.09万t，造成库容损失8 015万m3。由于上游流域内的水土流失和面源污染，水体富营养化严重，已严重威胁到四平市人民的生产生活水源安全及经济的可持续发展。水土流失是面源污染的主要载体，必须采取有效措施，减少水土流失造成的危害，保障流域生态安全，实现经济可持续发展。
- Abstract:
- The area of Erlong lake basin is 3 676.00 km2,and the area of soil and water loss is 1 453.72 km2.The amount of silt which flow in Erlong lake reservoir is 10.101 million tons,which result in loss storage capacity 80 million m3.Because the soil and water loss and surface sources of headwaters basin are polluted,water eutrophication is severe.It has already badly threatened the headwaters of people’s production,living and economy sustainable development.Soil and water loss is the main carrier of surface source pollution,effective measure should be adopted to reduce the hazards,and to ensure basin ecological safety and sustainable development.
