摘  要：
试验以人工湖泊毗邻的放牧草地为研究对象,测定人工湖对放牧草地土壤理化性质和植被特征的影响,为放牧草地的改良提供一定的科学基础和理论依据。3年的研究结果表明:随着湖距的增加,土壤含水量、土壤pH值呈降低趋势,土壤电导率(EC)值呈现增加趋势。其中土壤含水量、土壤电导率在0～10cm土层最高,并随土层加深逐渐降低;pH在不同土层间无明显差异。在建湖3年后,距湖区较远的表层土壤含水量高于相同距离下建湖初期的。距湖越近,植被生长状况越好,其生物量、盖度、多样性均有所增加。

摘  要：
Lake,an important resources in wetland ecosystem,can not only provide water also improve the soil physical-chemical properties and sustain the diversity.We evaluated the effects of artificial lake on the soil and vegetation characteristics of grazing grassland.The results of three years' study showed that with the increase of lake distance,soil water content and soil pH value decreased;soil electrical conductivity(EC)value increased.Among them,soil moisture content and soil electrical conductivity were the highest in 0～10 cm soil layer,and gradually decreased with the deepening of soil layer;pH value had no significant difference between different soil layers.After three years,the water content of surface soil is higher than that in the first year of the experiment in far from lake area.The nearer to the lake,the better the vegetation condition is,and the biomass,coverage and diversity of plants increased.We suggest that artificial lake has positive effect on the adjacent grazing grassland.
