摘要
本文根据赣江流域实际,将赣江中下游河道内生态环境需水分为河流基本生态环境需水、冲淤输沙需水、蒸发渗漏需水、自净需水,其中河流基本生态环境需水采用多种方法进行计算,并通过Tennant法进行检验;最后,各种功能的生态环境需水采用最大值法得出赣江中下游河道内生态环境需水.
In order to maintain the ecological balance of the middle and lower reaches of Gan Jiang River and promote water resources sustainable development,the study of Eco-environment water requirement of the middle and lower reaches of Gan Jiang River is imperative.According to the actual condiction of Gan Jiang Basin,the Eco-environment water requirement of the middle and lower of Gan Jiang is divided into the basic eco-environment water requirement of channel,sediment transmission water,evaporation and seepage water requirement,self-purification water requirement.Basic eco-environment water requirement of channel is calculated by using a variety of methods,these methods are tested by the method of Tennant.Finally,the Eco-environment water requirement of each control sections is obtained by choosing the maximum of all kinds of Eco-environment water requirement.
