东北黑土“土壤水库”特征及渗透速率研究
Studies on the Characteristics and Permeation Speed of Soil Reservoir in Northeast Black Soil
摘要
Abstract
[Objective] The research aimed to reduce the soil erosion of black soil and protect the good production performance of black soil. [ Method ] By field sampling and laboratory analysis and other methods, taking eroded-land as control and farmland, forestland and wasteland as the research objects, the change characteristics and permeation speed of soil reservoirs were studied. [ Result] The order of the tetal storage capacity, flood detention storage capacity, storage capacity and the maximum effective capacity in different sample soils in 0 - 10 cm and 10 ~ 20 cm soil layers were as follows; forestland > farmland > wasteland > eroded-land,while the order of the dead storage capacity was farmland > forestland > wasteland > eroded-land. The reservoir capacity of all the plots in 20 - 80 cm soil layer was forestland > farmland > wasteland > eroded-land. The reservoir capacity of all the plots all showed the decreasing trend with the increase of the soil layer depth. [ Conclusion] The soil porosity was the main factor that affected the maximum effective capacity of soil. Soil permeability was icomprehensivey affected by soil bulk density and other factors.关键词
