摘　　要：针对整治后市西河河流系统的特点及主要生态环境服务功能目标,从水质功能达标、保护水生生物栖息地、景观娱乐用水三个角度,计算出市西河的各类生态环境水量,取其所需临界流量中最大的一个作为市西河河流生态环境水量。研究表明,市西河最小生态环境水量应为2.376m3/s,大于二桥断面河流实际水量0.914m3/s,必须通过调水或其它方式解决。By investigating the features of the Shixi River system after treatment and main ecological environmental functions of service targets, we calculated various ecological and environmental water demands in the following three aspects, including function target hitting of water quality, habitat protection of hydrobios and water demand for landscape and recreation. Maximum critical water flux from the above calculations was defined as the ecological and environmental water demand of the Shixi River. The results have shown that the minimum ecological and environmental water demand in the Shixi River is 2.376m^3/s, which is greater than 0.914 m^3/s (the water flux at the Erqiao segment of the Shixi River). It is urgent to input more water by regulating or other measures in order to maintain the ecological balance.
