| 摘 要： | 本文对重庆四面山林地土壤持水、蓄水和水分渗透特性进行了研究。结果表明:针阔混交林土壤具有较好的持水与蓄水功能,其土壤饱和持水量与非毛管持水量分别为274.43、66.05t/hm2;有效蓄水容量针阔混交天然次生林为107.82t/hm2,人工林为123.36t/hm2。阔叶林土壤渗透能力较强,其次为针阔混交林、针叶林。阔叶林土壤水分初渗速率与稳渗速率,天然次生林为46.500与3.257mm/min,人工林为37.917与2.088mm/min。Horton渗透模型对研究区内林地土壤水分入渗速率的拟合程度较好,r为0.959。天然次生林土壤持水性、蓄水性和渗透性优于人工林,应加强对人工林的管理,以提高其土壤水分性能。

| Abstract: | Soil water holding and storage capacities,as well as infiltration properties of different forestlands were studied in the Simian Mountains of Chongqing,southwestern China.The results showed that soils in the mixed broadleaf-conifer forests had the highest water holding capacity and storage capacity,with a saturated water capacity of 274.43 t /hm2 and a non-capillary water capacity of 66.05 t /hm2.The effective water storage capacity of natural secondary mixed forests was 107.82 t /hm2,while that of the plan... |
