桂林市四湖生态健康状况的对比性评价
Ecological Health Assessment for Four Lakes in Guilin
摘要
Abstract
In the research of the measures for the four lakes management in Guilin,the four lakes ecological health before and after the projects of "Two Rivers and Four Lakes" is evaluated with the comparison method,by selecting the input pollutants as external index,the nutrition state as environmental factor index and the phytoplankton and zoobenthos as ecological index.The assessment results show that the comprehensive nutrition state index (TLI) of the water body was 85-90 before retrofit.After retrofit,the load of BOD5,TN and TP into lake decreased by more than 77%,and TLI of the water body was 48-54,the diversity index was 3.6-5.1.Four lakes ecological health is getting better after the projects was completed in 2005.However,the eutrophication still exists and the four lakes are at the edge of eutrophication.Therefore,some measures are proposed to promote the ecological health of the lakes,such as by increasing the water diversion and strengthening ecological construction.关键词
