摘　　要：以模型和"3S"技术为基础,介绍了赣南地区水土流失及其影响因子的评价方法和获取途径。在弄清各因子含义和算法的基础上,确定和构建了适合赣南地区侵蚀环境的水土流失评价模型及其因子值获取方法;同时对赣南地区林下水土流失区的水土保持生物措施因子B值以及水土保持工程措施因子E值的算法进行了有益的尝试。The paper introduced the evaluation methods and acquiring ways of soil and water loss and its affecting factors of the southern Jiangxi by taking model and 3S techniques as a base.It determines and establishes soil and water conservation evaluation model and acquiring way of its factors values that suits to erosion conditions of the southern Jiangxi based on the conditions of making the implication and algorithm of each factor clear.In the meanwhile,it has made an attempt on algorithm of factor B value(biological measures for soil and water conservation) and factor E value(engineering measures for soil and water conservation) in the soil and water loss region under trees in the southern Jiangxi.
