摘　　要：通过示范区3年采集的水分数据,结合当地的降雨资料和气象资料,对比分析了半干旱退化山区在不同生态恢复与重建措施下土壤水分的运行恢复机制。研究结果可为集蓄利用有限的降水资源,培植和发展荒坡灌草植被,充分发挥区域灌草资源优势和植被的恢复建造提供科学依据。With the moisture data gathered in demonstration district 3 years,combining local rainfall information and materials, the operation recovery mechanism of soil moisture in semi-arid degraded mountain area by different ecological recovery and reconstruction measures is analyzed. Research result offers scientific basis for using the precipitation effeciently, cultivating and developing slope shrub and grass vegetation,fully bringing the advantage into play.
