| 摘 要： | 通过在希拉穆仁草原典型地带进行不同干草覆盖下的土壤蒸发实验,结果表明:在蒸发过程中,覆盖干草阻止了水分的垂直蒸发,提高了土壤湿度,降低了土壤的蒸发速度,延长了有限土壤水的持续期,且土壤蒸发量随着覆盖度的增加而减小,盖度为100%的土壤试样蒸发量最小。

| Abstract: | In order to control grassland degradation and protect biological resources,keep a benign cycle of ecology-society-economy.This paper is with restoration ecology as guide to analyze the factors leading to grassland degradation,study on different material covered to impact on soil moisture in typical steppe zone through the soil evaporation experiments of the different material covered.The results show that: in the whole evaporation process,soil evaporation of 100% hay covered is the smallest. |
