武汉市滨湖景观格局演化研究

摘要

武汉市素有“百湖之市”的雅称,城市湖泊数量之多,全国居首.近年来,由于城市无序扩张与人为因素的干扰增多,武汉市湖泊出现水土流失,湖泊变浅,滨湖建筑群无序扩张,滨湖物种被固化和渠化的驳岸驱走等问题.该文运用生态网格分析和量化统计的方法,将武汉市1978年、1989年、2000年和2009年的滨湖景观格局作为研究对象,针对其演变的过程总结出演变规律,为日后武汉市滨湖景观格局建设与规划提供理论依据与数据支持.%Wuhan City is renowned as "the city of hundreds of lakes" since it leads other cities in China in terms of the number of lakes within urban areas.However,in recent years,due to rampant urbanization and increasing anthropogenic interference,Wuhan's lakes are confronted with a variety of problems,including soil erosion,shallowing lakes,sprawling lakeside buildings,and lakeside species dispelled by cured and channelized revetments.This paper adopts ecological network analysis and quantitative statistics as its research methods,takes the unit of analysis as the lakeside landscape pattern of Wuhan City,and studies it at four different times,namely at the years of 1978,1989,2000 and 2009,and identifies the laws goveming the changes of the pattern with time,thus providing theoretical basis and data support for future planning and construction of Wuhan's lakeside landside pattern.
