健康的河湖生态系统可以涵养水土、保护植被、调节气候、净化环境、美化景观,保证生态系统各种生物链条的正常运转,实现生态系统的良性循环。水土流失淤积河道、湖库,降低水资源利用率,并且污染水体、影响水质,对河湖的水量和水质影响都很大。通过水土保持生态修复,恢复生态系统的自身功能,减少水土流失,从而达到促进河湖健康的目的。
Healthy rivers and lakes ecosystems can conserve water and soil, protect the vegetation, regulate the climate, purify the environment, beautify the landscape, to ensure the normal operation of various biological links in the ecosystem, and to achieve a virtuous circle of ecosystems. Soil and water loss sedimentation of rivers and lakes, reducing water use efficiency, and pollute the water body, affecting water quality, the water and water quality of rivers and lakes have a great impact. Through the ecological restoration of soil and water conservation, restore the ecosystem’s own functions and reduce soil erosion, so as to achieve the purpose of promoting the health of rivers and lakes.
