引言三峡水利工程举世瞩目。对这项工程进行环境评价及对策研究,在经济上和科学上都具有重大现实意义和长远历史价值。进行大型环境综合性研究,除采用多学科协作攻关外,还要从大环境的角度,应用环境系统论的观点,系统地进行环境评价和建立优化模型。环境遥感方法,是完成上述任务比较有效的方法之一。大型水利工程的生态与环境效应是多层次的和多因素的,应用遥感方法可进行宏观整体的和微
Introduction Three Gorges water conservancy project has attracted worldwide attention. The project of environmental assessment and countermeasures research, both in economy and science have great practical significance and long-term historical value. In addition to using multidisciplinary collaborative research, we must conduct a systematic environmental assessment and establish an optimal model from the perspective of the environment and the environmental system theory. Environmental remote sensing method is one of the more effective ways to accomplish the above tasks. The ecological and environmental effects of large-scale water conservancy projects are multi-level and multi-factor. The application of remote sensing method can carry out macro and micro
