坡地生态系统退化与生态恢复对策——以鄂南丘陵山区为例

Evaluation for stability of slopeland ecosystem and study on restoring for degraded slope-land ecosystem——a case of the slope land in the south of Hubei province

对鄂南丘陵山区坡地生态稳定性进行评价的基础上,分析研究了不同类型坡地退化的特征、过程及主要影响因子;在提出区域土地利用结构调整并确定不同类型区土地利用整治方向的前提下,介绍了几种坡地退化防治的农业生态技术及其在本区实施和推广的重要意义.

Basing on the evaluation for the stability of the slope land resources in the south of Hubei province, this paper researches the feature, process and distinctive factors of the varying types of slope land resources. The degradation of slope land resource shows varying as a result of the diversity of topography, soil, climate, vegetation and the vary of human＇s disturbance and utilization. Correspondingly, some effective managements of landuse should be adopted for preventing slope land from further degradation. this paper introduces some techniques of eco-engineering for agriculture and offers some effective approaches to control the situation, such as Slope Eco-engineering and slope lands agricultural techniques of contour hedgerow.
