摘　　要：港口的建设会对生态环境产生影响,本文将港口建设产生的用地变化对生态环境产生的影响进行了定量化计算研究。本文通过运用RS技术,建立了港口生态系统服务价值计算模型并计算2000年和2013年大窑湾港口及其周边地区的生态用地服务价值及产生的变化。结果表明,2000年至2013年间,由于港口开发与扩建,建设用地面积大量增加,生态用地大幅度减少,其中草地和水域分别减少了56.25%和44.69%,从而导致该区域内生态服务价值的大量减少,总价值减少了约2.49亿元。本研究将港口建设对生态环境产生影响定量化,可以为港口建设者在规划设计工作中提供有效的参考。Port construction will affect local ecological environment. A quantified calculation research has been made for the impact of land-use change caused by port construction on local ecological environment. RS technique has been used to establish the calculation model of port ecosystem value-to-service, and calculate the ecological land value-to-service of Dayaowan port and the surrounding area in 2000 and 2013. The result shows that the area of construction land increases largely, but that of ecological land decreases sharply, among which grassland and water area decrease by 56.25 % and 44.69 % respectively due to port development and expansion from 2000 to 2013. The decrease of ecological land lowers local ecosystem value-to-service, which is reduced by approx. 249 million RMB. The above quantified study will serve as a reference for port planning design.
