摘　　要：港口建设改变了区域的生态环境要素,为研究其对区域生态环境需水的影响,本文以大连市长兴岛为例,基于RS、GIS技术和生态学方法对临港区域进行景观生态分类,构建临港区域植被需水、湿地需水和城市需水的计算模型,并对临港区域各类生态环境需水量进行对比,分析临港区域开发建设前后的生态环境需水量增加程度,从生态环境需水量的视角,为港口建设提供决策依据。Port construction changes the factors of ecological environment within a region. In order to research its influence on water requirement for regional ecological environment, based on Dalian Changxing island, the port-neighboring area has been classified from the aspect of landscape ecology by using RS, GIS techniques and ecological method. And the calculation models have been built to meet the water requirements for vegetation, wetland and urban area. The above different water requirements are compared to analyze the increment of water demand due to the exploitation of port-neighboring area. The above analysis will serve as a port construction decision basis from the aspect of water requirement for ecological environment.
