摘　　要：对甘肃省西北部肃北蒙古族自治县石包城乡以南约1 km处的榆林河源头东岸的湿地水环境进行调查采样,选择磷酸盐、氨氮等水质指标及水文流量进行测定分析,研究结果表明,放牧活动对湿地水环境有影响,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.Phosphate,ammonia nitrogen and hydrographic flow were determined and analyzed.The results showed that feeding had little influence on physicochemical property of water quality because light feeding activities of protected wetland didn＇t exceed the carrying capacity of wetland.
