摘要
为了探讨不同植被类型与土壤侵蚀的关系,选取沂沭泗河中上游、南四湖以东的沂蒙山区,使用中国植被类型分类表,得到不同植被景观类型的空间分布图,结合土壤侵蚀分布图,利用GIS交叉分类方法,得出了沂蒙山区不同植被景观类型与土壤侵蚀的定量关系。总体而言,沂蒙山区的温带落叶灌丛、矮林的土壤侵蚀最严重。
In order to discuss the relationship of different vegetation type and soil erosion, choosing Yimeng mountain area, using China＇s vegetation type classification table, this paper makes out the spatial distribution figure of different vegetation landscape type. Then combined with the distribution figure of soil erosion and took the means of GIS crossed classification, this paper obtains the quantitative relationship of Yimeng mountain area＇s different vegetation landscape type and soil erosion. Generally speaking, the soil erosion of temperate zone＇s defoliation brushwood and coppice are most serious in Yimeng mountain area.
