梅州市某生态灌区渠道断面节水改造设计研究

Study of Water Saving Reconstruction Section Design of an Ecological Irrigation District in Meizhou City,Guangdong Province

以广东省梅州市某生态灌区为例,针对灌区存在的渠道衬砌使得水系与附水生物环境相分离而致使相应自净能力减弱的问题,引入生态灌区建设理念,研究生态灌区断面的不同改造形式,在保证灌区渠道灌溉排水作用的同时,降低水资源浪费率,发挥其有利于保护生态环境的生态功能,解决渠道衬砌使得水系与其水生物环境相分离致使其相应自净能力减弱的问题。

Taking a certain ecological irrigation area in Meizhou City,Guangdong Province as an example,in response to the problem of channel lining in the irrigation area,which separates the water system from the attached biological environment and weakens the corresponding self-cleaning ability,the concept of ecological irrigation area construction is introduced,and different transformation types of ecological irrigation area cross-sections are studied.While ensuring the irrigation and drainage effect of the irrigation channel,the water resource waste rate is reduced,and its ecological function in protecting the ecological environment is played,Solve the problem of channel lining separating the water system from its aquatic environment and weakening its corresponding self-cleaning ability.
