中文摘要从系统序化的观点,分析了库区大农业主要环境因子的具有代表性指标的数量和警戒线,并进行了对比。发现它们都处于逆向演替或退化之中。这对库区大农业和三峡水库均十分有害。说明库区当前大农业的环境恶劣或恶化。应处于警戒状态之中。其主要原因是长期向自然过度索取,以牺牲环境为代价、发展人口的和物质的生产的结果。建议进一步研究大农业及其环境的调控(序化和优化);把对环境的逐步补救和防止新的破坏结合起来,开展新的生态建设工程。
英文摘要 The present situation of representative quantitative indexes for main factors of natural environment of agriculture in a broad sense is analysed,and compared with the warning lines of these indexes from a veiw of systematic ordering.It is indicated that these environmental factors are in reverse succession,or degenerating,which are very harmful to the agriculture in this area and the Three Gorge Reservoir.It is showed that the present natural environment of the agriculture in this region is in a state of warinig which results from long time abuse of natural resources,keeping on material production and population growth at the price of sacrificing environmental quality.For sustainalble development of this area,agriculture in the broad sense and its environmental control including ordering and optimation should be further studied to rehabilitate the environment and protect against its further destruction.
