生态治理措施对拉鲁湿地生态质量提升的作用分析

Analysis on the Role of Wetland Engineering in the Ecological Improvement of Lalu Wetland

拉鲁湿地位于西藏自治区拉萨市西北部,具有调节局地气候、固碳补充氧气、净化空气、净化污水等诸多生态服务功能。由于自然原因和人为因素导致拉鲁湿地遭受不同程度的破坏,如湿地面积减少、水环境变差、草场质量下降等。为提升拉鲁湿地的生态服务功能,对其进行一系列生态整治措施,包括水体生态堤、拦污栅等湿地工程。通过以上措施的成功实施,并针对工程前后的实际效果对比,拉鲁湿地生态环境有大幅度提升,其生态效果显著。

Lalu wetland is located in the northwest of Lhasa City,Tibet Autonomous Region.It has many ecological service functions such as regulating the local climate,fixing carbon and supplementing oxygen,purifying air and purifying sewage.Due to natural and human factors,Lalu wetland has been damaged to varying degrees,such as the reduction of wet land area,the deterioration of water environment and the deterioration of grassland quality.In order to improve the ecological service function of Lalu wetland,a series of ecological treatment measures have been taken,including water ecological embankment,trash rack and other wetland projects.Through the successful implementation of the above measures and the comparison of the actual effects before and after the project,it is concluded that the ecological environment of Lalu wetland has been greatly improved and its ecological effect is remarkable.
