研究超大型水库(总库容10~9m~3以上)的环境影响,涉及自然和社会的广泛领域.对上述领域环境参数的调查和监测,不仅要力求具有连续性和准确性,而且还必须具有较大的区域性.已有资料表明,当代的遥感方法能迅速而经济地提取超大型水库环境影响的各参数.特别是水库建成前后,以及各运营阶段所产生的诸多环境要素:上游淹没、塌岸、
To study the environmental impact of very large reservoirs (with a total capacity of 10 ~ 9m ~ 3) involves a wide range of natural and social fields, and the investigation and monitoring of environmental parameters in the above fields should not only seek continuity and accuracy, but also have Larger regional data have shown that contemporary remote sensing method can quickly and economically extract the parameters of the environmental impact of very large reservoirs, especially before and after the completion of the reservoir and the various environmental elements generated during each operation phase: upstream flooding, Bank collapse,
