黄河三角洲的环境资源系统结构

在分析黄河三角洲自然环境和自然资源特点的基础上,本文采用解释结构模型（ＩＳＭ）理清各要素之间的关系,并对环境资源系统整体结构进行了探讨。

THE STRUCTURE OF THE ENVIRONMENT AND RESOURCES SYSTEM OF THE YELLOW RIVER DELTA

On the basis of analysing the characteristics of the physical geographic environment and natural resources of the Yellow River Delta,this paper studies the integral structure of the environment and resources system of the region with the Interpretation Structure Medel (ISM).This paper chooses 9 environment factors, 7 superior resources and 6 disastrous or restrictive elements to niake the structure matrix separately. And by using the ISM to tidy up the relations among the elements,three system structure graphs are obtained. Then they are integrated into a great environment-resources system of the Yellow River Delta.After analysing the graphs of the system structure, this paper reaches the following conclusions:1. The structure of the environment and resources system is an entirety. It should be studied and perfected with a comprehensive and systematic view. Only when it has the structure function superiority of the entirety it can realize the real superiority of environment and resources.2. In regional development, the resources exploitation often occupies the key position. In the Yellow River Thlta, oil and land resources should be exploited first. These can bring about the comprehensive exploitation of other resources. The reglon will finally be bullt into an oil energy hase, an oil and salt cheniical industrial base and bases of agriculture, animal husbandry and fishery.3. In the temtorial management of the Yellow River Delta, great attention must be paid to the important problem of the root, middle links, results and appearence of the environment change. These include the Yellow River Mouth management of ground water, saline-alkali land and ecological fragllity. The final goal is to transform and overcome the bad conditions to promote a well cycle of the environment and resources system.
