摘要
阿拉善属于我国水土流失比较严重的地区,尤其以风蚀为主。本文以阿拉善经济开发区为对象,研究防治当地土壤侵蚀的水土保持植物措施。根据立地类型,结合地形、土壤、植被、水分等条件,将研究区分为6水土保持分区。同时选取耐干旱、耐贫瘠和耐风沙的植物种,作为水土保持优选草树种。分别不同区域进行水土保持措施的布设,为当地水土保持工作的开展提供科学依据。
Alashan is serious soil erosion areas of China,particularly in wind-based.In this paper,the economical development area in Alashan researched the vegetation measures for preventing soil erosion as a case.According to the site type,combined with the topography,the soil,the vegetation,the moisture and other conditions,the study area is divided into six soil conservation districts.The plants resisting to drought,poor and aeolian sandy are the optimal selected grass and tree species for soil and water conservation species.Soil and water conservation measures were planned and designed in different regions,in order to provide scientific basis for the local soil and water conservation.
