基于遥感技术的十八里长峡自然保护区保护效果监测与评估

The monitoring and evaluation of protective effectiveness in Shibalichangxia Nature Reserve of Hubei based on Remote Sensing technology

基于2000年、2010年Land TM/ETM数据,建立研究区域的生态系统分类体系,分析研究区域内的生态系统格局变化.运用ALOS(2.5m)的高分遥感卫片进行人工目视解译,分析研究区域内的人为活动干扰情况,整体评估自然保护区珍稀野生动植物的保护效果,评估结果表明:10a间研究区域内生态系统格局变化较小,对珍稀动植物及其生境的影响甚微,人类活动形式较为单一且主要分布在实验区,2000至2010年期间,十八长峡自然保护区的管护工作是有效果的.

On the basis of Landsat TM/ETM images, the classification system of ecosystem in study area was established, in order to analyze the variation of landscape pattern. With artificial visual interpretation, study on the the artificial interference in Shibalichangxia Nature Reserve and evaluation on the protective effectiveness of rare species were accomplished. The results showed that the variation of landscape pattern and influence on rare species were not significant. Artificial interference was relatively single and distributed mainly in experimental zone at a low level. These suggested that the management and protection of Shibalichangxia Nature Reserve were productive between 2000 and 2010.
