| 摘 要： | 在对北京市各种类型土壤进行调查的基础上,采用美国土壤学家D.W.Fryrear等人的计算土壤可蚀部分含量方程,计算北京主要土壤类型(亚类)表层的可蚀含量,建立了北京市可风蚀性数据库。用Region Manager地理信息系统制作北京土壤可风蚀性风分级图,并对北京地区主要土壤类型的可风蚀性进行分析与讨论,为正确评价北京土壤风蚀危害提供科学依据。

| Abstract: | Based on the investigation of the soil types in Beijing,we adopt the method published by D.W.Fryrear et al to calculate erodible fractions of the soils,and the database is attained.The Region Manager is adopted to create the regionalism map of the erodibilities of soil types in Beijing.Based on the database and the regionalism map,the erodibilities of main soil types are analyzed and discussed.The paper provides scientific basis for correctly evaluating the risk of wind erosion. |
