摘要
葛洲坝水利枢纽工程是长江中下游第1座大型水利水电枢纽工程,1971年开工建设,1988年投入运行以来,至今已30+a。通过建设前的1968年延续至2015年近50a共5期的遥感影像,解译分析葛洲坝水利枢纽工程建设可能对宜昌市五区土地利用格局产生的影响。通过研究认为葛洲坝水利枢纽工程建设未改变宜昌市五区的土地利用总体格局,但对工程直接影响区产生了一定影响;工程建设对宜昌市城市集群效应有一定影响,随着葛洲坝水利枢纽工程建设,从1987年至2005年宜昌市城市发展有明显的在葛洲坝左岸聚集的趋势,但随着时间延长,此种影响逐渐减小。
Gezhouba water conservancy project is the first large-scale water conservancy and hydropower project in the middle and lower reaches of the Yangtze River,which started construction in 1971 and has been put into operation in 1988 for more than 30 years.Based on five remote sensing images from 1968 to 2015,this paper interprets and analyses the possible impacts of Gezhouba water conservancy project construction on land use pattern in five districts of Yichang City.Through the study,it is considered that the construction of Gezhouba water conservancy project has not changed the overall pattern of land use in five districts of Yichang City,but it has certain influence on the urban cluster effect of Yichang City.With the construction of Gezhouba water conservancy project,the urban development of Yichang City from 1987 to 2005 has a clear tendency to gather on the left bank of Gezhouba,but the impact decreases with time.
