摘要 以“长江流域水土流失遥感调查与监测”项目部分研究成果为依据,选择经济活力较强、经济发展较快的长江中下游地区,分析了该
区水土流失的分布特征,研究了诱发水土流失的人类不合理活动,探讨了相关地质因子与水土流失的成因关系,总结了水土流失的主要类型
及其变化趋势,并提出了合理防治的建议。

Abstract :In this study, part of the research results of the project “The Remote Sensing Investigation and Monitoring of
the Soil Erosion in Yangtze Valley” was employed as the basis, and the area of middle and lower reaches of the Yangtze
River was chosen as the study area in that this area is characterized by strong economic vitality and fast economical
development. The distribution characteristics of the soil erosion in the middle and lower reaches of the Yangtze River were
analyzed, the unreasonable human activities inducing soil erosion were studied, the original relations between the
correlative geological factors and the soil erosion origin were investigated, and the predominant soil erosion types and
their change tendency were summarized. On such a basis, some reasonable suggestions concerning soil erosion prevention and
control are put forward.
