太湖流域景观空间格局动态演变
Dynamic evolution of landscape spatial pattern in Taihu Lake basin, China
摘要
Abstract
Based on the land-use satellite image datasets of 2000,2010 and 2015,the landscape index,dynamic change model,landscape transfer matrix and CLUE-S model were integrated to analyze the dynamic evolution of the landscape spatial pattern of Taihu Lake basin.The results showed that the landscape type of the basin was dominated by cultivated land and construction land,and the degree of landscape fragmentation was strengthened from 2000 to 2015,and the distribution showed a uniform trend.From the point of transfer dynamic change,the cultivated land and construction land changed significantly,which was reduced by 6761 km2(2.1%) and increased by 6615.33 km2(8.4%),respectively.From the landscape transfer,it could be seen that the main change direction of the cultivated land reduction was the construction land,and the cultivated land with 7866.30 km2 was converted into construction land,accounting for 91.6% of the cultivated land change,and the contribution to the construction land was 96.5%.The trend of dynamic changes of cultivated and construction land in the counties and cities was the same as that of the whole Taihu Lake basin.For Shanghai Central Urban,as well as Pudong District,Lin'an City,Baoshan District,Minhang District,Jiading District and Changzhou City,the area of the cultivated land and construction land changed more prominently.However,compared with the CLUE-S model for the landscape pattern change in 2030,the change of cultivated and construction lands would be the largest in the natural development scenario.Under the ecological protection scenario,the area of grassland would increase and the dynamic degree would reach 54.5%.Under the situation of cultivated land protection,the conversion of cultivated land to construction land would be decreased.关键词
