Ecology plan on the city wetland

为改善城市生态环境和居住条件,需开展城市湿地生态修复和重建工作。其重点在于退地还水,扩大湿地面积;增加物种的组成和生物的多样性,提高湿地生态系统的生产力和自我维持能力;提高土壤肥力,逐年增加植被的覆盖度,充分利用地表径流循环,维持湿地水分的涵养。

In order to improve the ecology environment and living conditions, we should do something to rehabilitate the city wetland. The focus is to withdrawal of plantations and restore river water, to thereby enlargesthe city wetland, to increase species compositions and biodiversity＇ ,to enriche the wetland＇s ecosystem productive forces and self-maintenance ability,to enhance soil fertility and vegetation＇ s coverage ratio, keeps vegetation＇s coverage to using surface water runoff circulation, to maintain the water contain of the city wetland.
