摘  要：
以青土湖过渡带3个不同立地类型(常淹水中的白刺沙包、固定白刺沙包、半固定白刺沙包)的白刺灌丛沙包为研究对象,采用了空间代替时间的方法,测定了间断性水淹前后白刺群落土壤水分、土壤电导率、pH、白刺生物量等参数。结果表明,3种立地类型的白刺沙包土壤电导率和pH随着深度的变化而有不同的变化。常淹在水中的白刺沙包不同部位的土壤含水量的变化较为平稳;固定白刺沙包不同部位的土壤含水量在浅层(0～20cm)相差较大,在较深层变化较小;半固定样地的各个部位土壤含水量相差不大。白刺的生物量从大到小依次为距离水50 m、离水200 m、离水100 m、水中,这说明土壤水分对白刺沙包生长有重要的影响,距离水50 m为白刺生长最佳距离。

摘  要：
The white thorn shrub sandbags of three different site types(white thorn sandbags, fixed nitraria sandbags, semi-fixed nitraria sandbags) in the Qingtu Lake transition zone were used as research objects, and space was used instead of time.The parameters of soil moisture, soil conductivity, pH and nitraria biomass of nitraria community before and after intermittent flooding were determined.The results showed that the soil conductivity and pH of the three site types of white thorn sandbags had different changes with depth.The soil moisture content of different parts of the white thorn sandbags often flooded in water was relatively stable.The soil water content of different parts of the fixed nitraria sandbags was larger in the shallow layer(0-20 cm) and smaller in the deeper layers.The soil moisture content of each part of the semi-fixed plot was not much different.The biomass growth of nitraria was away from water 50 m> away from water 200 m> away from water 100 m> water, which indicated that soil moisture had an important influence on the growth of nitraria sandbags.The optimal distance of nitraria growth was 50 m away from water.
