摘要
湖泊水域萎缩将会导致湖区的生态系统功能退化,改变湖泊生态环境与水域类型结构,使水生生物量及其种类构成发生变化,引起湖区生态环境的恶化。利用从1989—2012年之间共7个年份的遥感影像,提取皖江流域8个主要湖泊各年份的丰水期水域面积,计算各湖泊水域面积年变化信息,探讨各种人类社会经济活动对湖泊水域面积变化的影响程序。
The decrease of lake area will cause the change of lake ecological environment and water type structure,leading to the change of the aquatic biomass and species composition. consequently the ecosystem of the lake district functionally degrades. The main objective of this study was to explore the impact of human activities on lake area variations in the humid area. Based on LANDSAT TM images for the period from 1989 to 2012,this paper extracted annual water area of 8 major lakes during flood period in Wanjiang region,calculated the annual water area change information of each lake,and discussed the influence that kinds of human social and economic activities change the water area of lakes.
