摘要

该文通过页岩岩性的分析，得出在三峡地区湿热多雨的气候条件下，页岩极易风化崩解，植被破坏后，水土流失严重。页岩强侵蚀区具有：（1）抗风化能力弱，侵蚀发展快，崩岗发育；（2）土地贫瘠，生境恶劣，植物生长困难；（3）“三料”俱缺，经济落后等特点。根据这些特点和宜昌县的治理实践，提出以下治理措施：（1）建立以工程为先导治标，植物为目的治本的防护体系；（2）治坡与治沟相结合，加强对崩岗的整治；（3）治理与开发相结合，建立水土保持产业；（4）开能与节能相结合，加强监督管护，建立综合防治保障体系。

Abstract

Based on shale properties analysing

the results obtained are that shale is easy to weather under the humid and hot climate condition

when vegetation is destoried

soil and water loss will be more serious.Shale erosive area has following characters:(1) low capacity to resist weathering;(2) sterile soil and wick ecological environment;(3) economic backwardness. According to those characters and control practice of Yichang county

Hubei province

many control measures are put forward:(1)constructing protective system of vegetation;(2)controlling gully slope combining with gully;(3)combining control with exploit;(4)combining use with energy saving and building comprehensive protective system.
