改善生态环境防治长江上游水土流失
- Title:
- Control of Soil and Water Loss in the Upper Reaches of Yangtze River by Improving Ecological Environment
- 摘要:
- 长江上游长约4500km，流域面积约100万km2。本区域地理条件特殊，水力、矿产、动植物和旅游资源都十分丰富，具有巨大的经济发展潜力。近几十年来，由于本区域森林植被遭到严重破坏，垦殖率不断增高以及对资源的不合理开发利用，致使长江上游地区生态环境日益恶化，水土流失不断加剧。在长江上游地区自然生态系统遭到严重破坏的同时，也给长江中下游地区带来了巨大的危害。改善长江上游生态环境和防治水土流失，是实现流域可持续发展必须解决的重大问题。
- Abstract:
- The upper reaches of Yangtze river is about 4 500km long and has 1,000,000 km2 catchment. It has a special geographical condition. Its resources of water power, minerals, fauna, flora and travel are very abundant, and the area has a tremendous development potential of economy.In the past recent decades, the ecological environment and soil and water loss are more and more serious in the upper reaches of Yangtze river resulting from strong damage of forest and vegetation continuous reclamation of wasteland and unreasonable development and use of resource. The natural ecological system of the upper reaches of Yangtze river is strongly destroyed, at the same time the huge danger is also brought on the lower reaches of Yangtze river.Improvement of ecological environment and control of soil and water loss in the upper reaches of Yangtze river are the key subjects which are concerned with the sustainable development of the catchment.
