| 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3a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 which 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 Liangdang 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. |
