摘要

该文系统地分析了广东省1986～1992年造成人为水土流失增长的因素及其经济损失、增长速度与危害等，并针对这些形式提出防治的对策和措施。各因素造成危害的名次总和指数顺序为：基建工程>采矿>陡坡开荒>砖瓦窑>毁林毁草。单位面积经济损失为31.36万元/km2

年均面积增加414.06km2

年均流失量2926万m3.作者指出：人为水土流失的机理是开发建设对水土资源产生剧烈扰动，造成大量土壤侵蚀，加之随意堆弃和倾倒便为土壤流失准备了物质基础和环境条件。只要加强执法、监督和必要的水土保持预防和治理措施，大多人为水土流失是可以避免和防治的。

Abstract

Based on the data of man made soil and water loss(1986～1992) in Guangdong province

the authors studied the main factors of man made soil and water loss

and its economic loss

increasing rate and harm

then put forward the countermeasures of the prevention and control.The sequence of sum total index in all items is:capital constructionmining reclaiming wasteland with steepslopebrickkilndestroying forest and vegetation.The economic loss is 31.36×104yuan/km2 (RMB)

an average increase of 414.06 km2 and 2 926×104 m3.The authors put forward that man made soil and water loss result from the irrational human actions

as long as execution of the soil and water conservation

supervision and necessary measures of rehabilitation and prevention are enforced

much man made soil and water loss would be refrained

prevented and controlled.
