南方郊区小流域自然河流生态需水量的研究

Study on Ecological Water Demand of Natural Rivers in Small Watershed in the Suburbs of South China

针对南方郊区自然河流生态治理亟待解决的生态补水问题,以荆门地区浰河为例,开展生态补水需水量的研究,为同类河流的治理提供经验。通过对浰河生态需水量构成的分析,列出其主要组成为基础生态需水量、蒸发需水量、渗漏需水量、外取水量,依次结合浰河实际情况分析估算各项需水量,为同类河流快速经济地估算生态需水量提供相关经验。

Aiming at the ecological water supply problem of natural rivers in the suburbs of southern China,a case study of ecological water demand in Lihe River,Jingmen was done in order to provide experience for the control of the similar rivers.Based on the analysis of the composition of ecological water demand,the main components are listed as basic ecological water demand,evaporation water demand,leakage water demand,external water demand,and the water demand was analyzed and estimated accordingly.The study would provide relevant experience for estimating ecological water demand of similar rivers quickly and economically.
