桥山林区不同林分和坡位土壤水分对典型降雨的响应

open access: yesShuitu Baochi Xuebao
目的降雨是土壤水分补给的主要来源,直接影响着土壤水分的分布特征,进而影响植被的生长状况,为探明桥山林区不同林分和坡位土壤水分对典型降雨的响应规律。方法以黄土高原南部桥山林区为研究对象,通过对典型林分(阔叶纯林和针阔混交林)不同土层深度土壤水分和降雨的监测,探究不同植被覆盖和坡位条件下的各层土壤水分体积分数对典型降雨的响应特征。结果1) 研究期,降雨量主要集中在8月、9月、10月,其中9月的降雨量最大为251.7 mm。各样点同一土层的土壤水分体积分数季节性差异显著(p≤0.05 ...
