摘　　要：本文基于巢湖湖区1962—2017年长系列逐日水位资料,分析计算了巢湖历年特征水位及高低水位发生时间与历时;在此基础上分析确定了巢湖的生态水位,并对其生态水位保障程度进行了分析。主要结论有:(a)巢湖忠庙站最低生态水位为6.80m;(b)巢湖生态水位日、月、年保障程度均较高;(c)20世纪90年代中期以来,受湖区周边水资源开发利用影响,巢湖最低控制水位逐渐升高,虽有助于经济社会发展,但对湖区生态系统的可持续发展不利。建议积极开展巢湖生态水位调度研究,以保障巢湖生态系统健康。Based on the daily water level data from 1962 to 2017 in the Chaohu Lake area,this paper analyzes and calculates the annual characteristic water levels and the occurrence timing and duration of high and low water levels in the Chaohu Lake.On this basis,the ecological water level of the Chaohu Lake is determined,and the degree of ecological water level assurance is analyzed.The main conclusions are as follows:(1)The minimum ecological water level at the Zhongmiao Station in the Chaohu Lake is 6.80m;(2)The daily,monthly,and yearly assurance levels of the ecological water level in the Chaohu Lake are relatively high;(3)Since the mid-1990s,due to the demands of water resources development and utilization in the surrounding areas of the lake,the minimum control water level of the Chaohu Lake has gradually increased.Although this has contributed to economic and social development,it is unfavorable for the sustainable development of the lake’s ecosystem.It is recommended to actively conduct research on ecological water level regulation in the Chaohu Lake to ensure the health of its ecosystem.
