摘要
通过对水库水温结构类型分析计算,朱庄水库为分层型水库。对朱庄水库水温分层对水体的化学和生态影响进行分析。通过对朱庄水库分层产生的低温水对下游用水影响分析,低温水用于农业灌溉则对农作物产生不利影响。根据该区常规种植的农业作物冬小麦和夏玉米两种作物影响分析,两种作物生长季节气候环境不同,低温水对夏玉米影响大于冬小麦。为水温的控制和利用、保证供水质量提供科学依据。
Through analysis of reservoir water temperature structure type,Zhuzhuang Reservoir is a thermal stratification reservoir.The impacts of temperature stratification on chemical and ecological properties of the water body were examined in the paper.Cold water for agricultural irrigation imposed a negative impact on crops through analysis of impacts of low temperature water resulted from ZhuZhuang reservoir thermal stratification on downstream water.According to impact anlaysis of water temperature stratification on winter wheat and summer maize,two conventionally cultivated agricultural crops in the area,low temperature water imposed large impacts on corn than wheat because these two crops had different growing seasons.This study would provide scientific basis for water temperature control and utilization,and water quality guarantee.
