摘要:
以资源一号02C卫星PMS数据为主要的数据源,对四川省普格县开展了县域生态环境遥感调查工作,选取生物丰度指数、植被覆盖指数、水网密度指数、土地退化指数和环境质量指数5个评价指标分析研究区内的生物、植被、水资源、土地以及环境污染等情况,建立了针对资源一号02C卫星数据的普格县土地利用一级类遥感解译标志.遥感数据调查的结果主要用于生物丰度指数和植被覆盖指数的建立.最后评价结果显示普格县生态环境状况指数为82.08,评价等级为优,整体生态环境质量佳.研究表明,使用的县域生态环境质量评价方法可以准确、真实、有效地反映县域生态环境状况;国产卫星数据获得容易,成本降低,其中资源一号卫星遥感数据能够很好的满足县域遥感生态环境调查的需求.
Abstract:
With ZY1 - 02C as the main data source, the authors carried out the county area ' s ecological environment remote sensing survey in Puge Country, Sichuan Province, selected five evaluation indicators to analyze the biological, vegetation, water, land and environmental pollution in the area,which included biological abundance index, vegetation index, water density index, land degradation index, and environment quality evaluation index, and set up land use signs with the first class remote sensing interpretation sign for ZY1 -02C. The results of remote sensing survey are mainly used in the establishment of bioabundance index and vegetation cover index. The evaluation results show that ecological environment index (EI) of Puge is 82. 08, the evaluation level is excellent, and the overall ecological environment is good. The county ecological environmental quality assessment method can accurately, truthfully and effectively reflect the situation of county ecological environment. Due to using of domestic satellite, the data acquisition and cost reduction become very easy. Survey results show that ZY1-02 C can be very good in satisfying the requirements of county ecological environment remote sensing in-vestigation.
