| 摘 要： | 该研究借助遥感与GIS技术,考虑影响农业生态系统的关键因素,选取植被指数、地表温度、降水距平以及自然灾害等主要指标,建立了我国农业生态评价的指标体系。根据研究所提出的指标体系以及评价方法,开展了2006年3月上旬到10月上旬的全国农业生态综合评价,并详细分析了每个月我国各地区的生态状况,结果表明我国2006年农业生态总体状况比较好,只有个别地区比较差。该研究所提出的基于遥感与GIS的农业生态指数评价方法,可以及时有效地获取全国范围内农业生态系统状况,而且可以考虑长期业务化运行,它将能为全面掌握我国农业生产状况,保障我国农业平稳发展有非常重要的意义。

| Abstract: | Agricultural ecosystem is a complicated system with various factors. At present, evaluation of agricultural ecosystem performance has been done mainly on the basis of socioeconomic statistics data in a comparatively small area. With the development of science and technology, it is possible to monitor the ecosystem performance dynamically in a large area using remote sensing data. In this study we proposed a new approach to evaluate the performance of agricultural ecosystem in the whole China. The approach i... |
