摘要
在地理信息技术的支持下,从水土流失、石漠化、地质灾害、生态退化方面对曲靖市生态环境的敏感性进行综合分析.结果表明,曲靖市生态环境不敏感、中度敏感、高度敏感、极度敏感地区分别占研究区总面积的49.44%、32.51%、13.96%和4.10%.不敏感区分布于西南走向;中度敏感区在全市均有分布;高度敏感区和极度敏感区主要分布于曲靖市东部和会泽县西南部.
Abstract
With the support of geographic information technology,a comprehensive analysis was made of Qujing's eco-environmental sensitivity from four aspects:soil erosion,rocky desertification,geological di-saster and ecological degradation,and the results showed that the areas of insensitive,moderately sensi-tive,highly sensitive and extremely sensitive ecological environment in Qujing accounted for 49.44%,32.51%,13.96%and 4.10%,respectively.The insensitive areas were distributed in a southwest direction,the moderately sensitive areas distributed across the whole city,and the highly sensitive and extremely sensitive areas mainly distributed in the east of Qujing and southwest of Huize County.
