太湖旱警水位确定分析

Analysis of determining drought warning water level in the Taihu Lake

在分析现有太湖干旱预警相关特征水位基础上,根据太湖流域实际用水情况,开展了太湖旱警指标选取及环太湖规模以上取水户的取水口高程、环太湖口门建筑物闸底高程、太湖通航保障水位和生态水位等指标分析,综合考虑以上各指标的最低水位要求,结合太湖流域抗旱需求,建议将相关指标的最大值2.80 m作为太湖旱警水位。

Based on the analysis of the existing characteristic water levels related to drought early warning in the Taihu Lake,according to the actual water use in the Taihu Lake Basin,the selection of drought warning indicators in the Taihu Lake and the analysis of the indicators such as the elevation of water intakes around the Taihu Lake,the elevation of gate bottom of buildings around the Taihu Lake,the navigation guarantee water level and ecological water level in the Taihu Lake were carried out.Considering the minimum water level requirements of the above indicators and the drought resistance demand in the the Taihu Lake Basin,it is suggested that the maximum value of 2.80 m of relevant indicators be taken as the drought warning water level in the Taihu Lake.
