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
In this paper, we observed the soil structure, physicochemical properties, crown retention, trunk retention, litter retention, surface runoff and runoff sediment concentration of different forest species in the Manchurian black forest. In the area, the value of runoff benefit was higher in forestland than in non-forestland. Among them, the value of runoff benefit of larch, Populus simonii and natural oak forest was the highest in forestland, and the runoff benefit value was the largest in Larch forest. small
