摘要/Abstract

摘要： 对荒漠草原不同放牧强度下主要植物的日蒸散量及其根部土壤含水量进行了研究。结果表明,短花针茅根部的土壤含水量随着放牧强度的增加呈增加趋势;冷蒿、无芒隐子草表层根部的土壤含水量随放牧强度的增加变化不大。相同放牧条件下,短花针茅个体日蒸散量相对较大,冷蒿个体日蒸散量相对较小。土壤含水量同植被日蒸散量具有高度的正相关关系。

Abstract: The daily evapotranspiration of dominant plants and soil moisture around their roots under different conditions of grazing intensity in desert steppe were studied. The results show that soil moisture around roots of Stipa breviflora increased with the increase of grazing intensity; soil moisture in the surface soil around roots of Artemisia frigida and Cleistogenes songorica did not change obviously with the increase of grazing intensity. Under the same condition of grazing intensity, the daily evapotranspiration of S. breviflora was relatively larger, while the daily evapotranspiration of A. frigida was relatively smaller. The daily evapotranspiration of vegetation had highly positive correlation with soil moisture.
