摘　　要：采用武汉市2015年和2020年遥感影像提取水体及建成区边界,研究了湖泊面积变化强度与建成区距离的相关性.并通过对面积变化强度较大的湖泊周边开发建设的特征分析,提出相应的规划应对策略,研究的主要结论:(1)武汉市域范围内的大多数湖泊在研究时限内发生了不同程度的收缩,收缩幅度存在空间异质性;(2)距离建成区近的湖泊收缩强度大;(3)湖泊周边道路交通设施增加、可达性提高,带来人类活动强度和建设速度增加,是湖泊收缩的主要因素。This article uses remote sensing images of Wuhan from 2015 to 2020 to extract the water vector and the boundary of Urban built-up area,and studies the correlation between the variation of lake area and the distance between the boundary line of Urban built-up area and the lake.Through the analysis of the characteristics of the construction and development of the lake area with strong area change intensity,the corresponding planning response is put forward.The study finally reaches the following conclusions:①The vast majority of lakes in Wuhan experienced varying degrees of area shrinkage during the study period.There is spatial heterogeneity in the shrinkage of individual lake areas.②Lakes close to built-up areas have high shrinkage intensity.③The increase of road traffic facilities and the improvement of accessibility in the lake area have increased the intensity of human activities and construction activities,which is the major factor in lake shrinkage.
