| 摘 要： | 针对目前生态质量气象评价在气象业务开展中存在的问题，采用“3S”技术，结合地面气象观测资料，开展了以卫星数据为主的北京地区的生态质量气象评价方法研究，重点对植被覆盖指数与土地退化指数进行了方法研究，并以北京2006年第二季度为例开展了以区县为评价单元的生态质量气象评价，评价结果与实际较为一致。研究结果表明：基于卫星数据的生态质量评价指标信息提取及评价方法具有实践意义。

| Abstract: | Present meteorology evaluation of ecological quality has some difficulty in practical use and satellite data are not used adequately. By using the 3S technology, the methods of extracting information of ecological quality indexes mainly by satellite data are studied, especially in extracting information on vegetation coverage index and soil degradation index. And these methods were applied for meteorology evaluation of ecological quality of Beijing in the second season in 2006. The evaluation results are satisfying and also show that the methods of extracting information on ecological quality indexes with satellite data are feasible and practical. |
