| 摘 要： | 本文通过典型研究发现,近十几年来连续干旱和过量超采地下淡水,是导致山东沿岸海水向内陆地下入侵的主要原因。由此酿成了严重的生态灾害:水生态、农田生态、滨海盐土生态、城镇经济生态和生态工程环境严重恶化,造成海水入侵区水源破坏、农田减产或绝产及盐生天然植物生态群落向内陆扩展,干扰了工农业和工程规划布局以及社会文明和人民生活,提高了地方病发病率。

| Abstract: | In this paper,the authors discussed the patterns of some ecological cha nges caused by seawater intrusion in Shandong Province.They are put forward as fellows: 1. A close relationship exists between natural precipitation and seawater intrusion. When natural precipitation was less than 550mm.,seawater intrusion occurved in Shandong Province. 2. After seawater intrusion took place the quality of the underground water became worse; The quantity of water respirces and quantity of the resources of the cultivated land were damaged and their productivity dropped; on the contrary, the halobiotic communities developed and extended landward; the industries in the city and the countryside were affected a well as the peoples livelihood and health. |
