太行山石灰岩区土地利用变化及区域生态效应

Land Use Change and Associated Effects on Eco-Environment in Lame Stone Region of Taihang Mountain

基于数字化的航片,对刘家流域土地利用变化的区域生态环境效应进行了定量分析,结果表明:生态环境质量改善和恶化的两种趋势并存,但是导致区域生态环境改善地类的贡献率要远远高于恶化地类的贡献率;该区域的总体生态环境质量发生了根本转变,生态环境有了显著的提高,人工林地面积的增加是区域生态环境改善的主导因素。

<Abstrcat> Based on the aviation photograph of digitization, the regional eco-environment contribution associated by the process of land use change in Liujia region was measured and qualified, the results showed that the trend of both improvement and degradation in eco-environment was co-exist, but the major land use change type improving the regional eco-environment was far higher than land use change type reducing ecological environmental quality. Environmental quality had changed greatly overall on this area, and the ecological environment had remarkable improvement. The increasing artificial forest land area was the improved main factor of the regional ecological environment。
