黄河三角洲地区靠近渤海湾,遍布滩涂湿地资源,生态环境比较复杂。该文通过建立“生态敏感性生态压力度”概念模型,构建生态环境脆弱性评价指标体系,通过数据标准化将指标统一量纲,最后根据数学模型计算评价区生态环境脆弱性指数,并分为5个等级。经计算,西北部沿海地区生态环境脆弱性等级较高,主要指湿地及盐渍化比较集中的东营市北部地区,南部地区相对较低,尤其是远离海岸线的地区。并针对评价中存在的问题进行了讨论。

The Yellow river delta area is near Bohai gulf. It has abundant mudflat wetland resources. The ecological environment in this area is very complex. In this paper, by using conceptual model of"ecological sensitivity———ec?ological pressure degree", ecological environmentl vulnerability evaluation index system has been set up. Through data standardization, the index unified dimension has been made, then according to the mathematical model, eco?logical environment vulnerability index have been calculated and divided into five grades. It is showed that ecologi?cal environment vulnerability level is high in northwest coast ,mainly distributed in northern dongying city which is concentrated wetland and salinization; the southern region is relatively low, especially the areas away from the coast. Finally the problems existing in the evaluation were discussed in this paper.
