| 摘 要： | 以希拉穆仁草原为研究对象,通过对不同植被覆盖下土壤水分进行测定,研究了荒漠草原植被覆盖对土壤水分的影响,结果表明:植被覆盖度与土壤水分之间具有显著的相关关系,尤其是10 cm深度范围内土壤水分随植被盖度呈二次抛物线性趋势增加(R2=0.904 9);由于根系层分布的差异使得土壤剖面不同深度上对这种影响的水分响应不尽相同,灌丛植被覆盖的土壤水分含量在剖面0～40cm范围内明显大于其他植被类型,以坡顶土壤含水量最低;荒漠草原植被覆盖状况变化不仅影响土壤水分含量大小,而且显著影响土壤水分的空间分布,退化较轻的河滩草甸植被有利于维持相对均匀的土壤水分空间分布. |

| Abstract: | Taking the Xilamuren grassland as studying object,through measuring the soil moisture under different vegetation coverage,the influence of vegetation coverage on soil moisture in desert grassland is studied in this paper.The results show that there exists significant positive correlation between soil moisture and vegetation coverage.Especially in the range of 10 cm depth,the increase tendency of the soil moisture with the increase of the vegetation coverage depth is quadratic parabola.Due to the difference ... |
