【摘要】 本文通过观测 ,对黑土漫岗林网区不同林种的土壤结构及理化性质、树冠截留、树干截留、枯落物截留及地表径流、径流含沙量的测定 ,测定出在黑土漫岗林网区 ,有林地比无林地的径流效益值大 ,其中有林地以落叶松、小黑杨、天然栎林的径流效益值较大 ,以落叶松林的径流效益值最大 ,果树林的径流效益值较小更多还原

【Abstract】 Measurements of soil structure, physical properties, crown interception, stem interception, litter interception, surface runoff and sand content of runoff in woodnets regions showed, that benefit values of runoff of woodlands were larger than that of lack of woodlands, and the woodlands with larch, natural oak had the larger values, and larch was even more, Benefit value of fruit woodland was less.更多还原
