The Change of Urban Landscape Pattern and Its Driving Forces——A Case Study in Wuhu City,Anhui Province
摘要
Abstract
As a representative of medium-sized cities in the middle and lower reaches of the Yangtze River,it is of great significance to study the change of land use landscape pattern in Wuhu for promoting regional environmental protection,resource utilization and economic development.This paper selected the TM images of Wuhu City in 1995,2005,and 2015 as the basic data,extracted the land use data with the technical support of RS and GIS.The landscape indices were used to analyze the landscape pattern characteristics of land use and the processes of landscape fragmentation in Wuhu.The transfer matrix and the unstable patch map were applied to analyze the changes and stability of landscape types.Finally,the driving forces were identified.The results showed that:the landscape types in Wuhu were mainly cultivated land,forest land,construction land and water area.The landscape index showed that the landscape pattem had changed significantly in the past 20 years.The transformation of various land landscapes was obvious,and the transformation relationship became more complex with time,the cultivated land area was reduced,the increase of forost land gradually replaced the dominant position of cultivated land,cultivated land and forest land were the most important transferor and transferred reader.The transfer probability of grassland and unused land was the highest,and it was easiest to transform.Within 20 years'span,the fragmentation of landscape pattern in Wuhu was accelerated and deepened,and showed instability in both time and space.These changes were combined with the precipitation and temperature changes,population and socio-economic growth,and government decision-making and other factors.关键词
