摘　　要：研究主要对甘肃省西北部肃北蒙古族自治县石包城乡以南约1km处的榆林河源头东岸的湿地水环境进行调查采样,选择盐度、TDS、电导率、pH等水质理化指标进行测定分析,由实验结果可以看出,放牧活动对湿地水质理化指标有影响,受到保护的湿地由于放牧行为较少,没有超出湿地的承载能力,因此影响较小。The article took wetland water environment of the east headstream coast of Yulinhe River, 1 km south of Shibaocheng County of Gansu Province as the investigating and sampling plot. Salinity, TDS（Total Dissolved Solid）, conductivity and pH were determined and analyzed. The results showed that feeding had little influence on physicochemieal property of water quality because light feeding activity of protected wetland didn＇t exceed the carrying capacity of marsh.
