摘要:
以毛乌素沙地覆盖度>90%的油蒿、50%~60%的沙柳、35%~40%的樟子松固定沙丘为研究对象，流动沙丘为对照，采用自动监测系统实时监测降雨、0~200 cm土壤含水量及200 cm以下渗漏量，分析5—11月不同固沙植被下沙丘土壤水分动态差异，以期为固沙植被稳定性评价提供参考。结果表明：较低覆盖度樟子松与高盖度油蒿、沙柳相比更具固沙优势。3种固沙植被表层0~30 cm土壤水分受降雨影响大，对>20 mm降雨均产生响应；60~200 cm土壤水分时间变化特征存在差异，樟子松与对照变化趋势一致，油蒿和沙柳仅对40 mm降雨产生响应；0~200 cm土壤水分垂直变化没有相同规律，变异性较大，樟子松变幅最大，为(5.03±3.09)%；深层渗漏特征基本一致，均有极少量水分渗漏到200 cm以下。
Abstract:
Taking the dune soil under the main sand-fixing vegetation Artemisia ordosica (coverage 90%),Salix psammophila (coverage 50%-60%),Pinus sylvestris var.mongolica (coverage 35%-40%) in Mu Us Sand Land as test object.The auto-monitoring system used to quantitative monitor precipitation,soil water for 0-200 cm depth,200 cm following leakage water.Analysis for dunes soil moisture dynamic characteristics in different sand-binding vegetation and provides reference for vegetation suitability,stability and sustainability,in order to provide a reference for the stability evaluation of sand-fixing vegetation.The results showed that greater than 20 mm rainfall was large effect 0-30 cm soil moisture.Differences for 60-200 cm soil moisture dynamic characteristics,the P.sylvestris and control the same trend,greater than 40 mm rainfall can be influence 60-200 cm soil moisture for the A.ordosica and S.psammophila.The 0-200 cm vertical variation of soil moisture variability was large and among P.sylvestris has maximum amplitude for (5.03±3.09)%.The three sand-fixing vegetations had water leaking into the following 200 cm depth and consistent with deep percolation characteristics.Overall,low coverage P.sylvestris had good sand-fixing advantage.
