| 摘 要： | 以毛乌素沙地铺设PLA沙障的新月形沙丘不同部位0-60 cm的土壤水分为研究对象,通过野外实地观测、采样和室内实验分析相结合的方法,对各个采样点的土壤含水量进行测量和分析。结果表明：土壤含水量受地形影响明显,从丘间低地、沙丘底部、沙丘中部到沙丘顶部土壤含水量依次降低;PLA沙障增强了沙丘土壤保持水分的能力,障格内土壤含水量明显高于裸沙丘上的土壤含水量,并且障格内土壤含水量变化趋势稳定,规律明显;PLA沙障对沙丘0-40 cm的土壤含水量影响较大。综合分析认为PLA沙障的配置在本研究区内对沙丘土壤水分保持有一定作用,能为后期的植被恢复提供有利的水分条件。

| Abstract: | In Maowusu Sandy Land,taking the soil moisture in 0~60 cm of different slope positions in barchan dune laid PLA sand-barrier as a study object,combining field observation and sampling with laboratory experiment and analysis,soil moisture in each sampling point was measured and analyzed.The results showed that the soil moisture was influenced by the terrain significantly,with decreasing consequently from the lowland,the bottom of dune,the middle of dune to the top of dune.PLA sand-barrier could enhance the s... |
