摘要

水土保持生态修复是一项注重依靠大自然的自我修复能力

在较短的时间内实现大面积水土流失初步治理

区域生态环境逐步恢复

人与自然和谐共处的水土保持措施。通过采用ETM+SPOT融合卫星影像对两当县水土保持生态修复项目区进行本底监测

结果显示经过近3 a的水土保持生态修复

项目区内植被状况发生了很大变化

植被覆盖率提高

植物群落向着正向演替的方向发展

水土流失面积和程度有所降低

各项生态因子明显改善。

Abstract

Ecosystem recovery is a soil and water conservation measure w hich relies on the ability of natural recovery.It greatly helps to control soil and water loss

resume environment

and make human and nature harmonious in a short time. The fusion of TM and SPOT images was applied in the ecosystem recovery monitoring of soil and water loss in Liang dang County. In the past three years

vegetation coverage was increased

plant community in the project area was changed towards a developing direction

soil erosion area and its degree were reduced

and ecological factors were distinctly improved.
