文摘内容 Taking the downtown area of Tianjin City and Beichen District,Xiqing District,Jinnan District and Dongli District in its neighborhood as the study area,TM remote sensing images(with a resolution ratio of 30 m)of 1993 and 2001 were utilized to analyze landscape structures and evolution characteristics of the study area by calculating its landscape pattern indexes with the help of ArcGIS9.3.The results showed that:A.Ratios of landscape components changed greatly,area ratio of each landscape component varied in different degrees.Area of farmland decreased from 32.7% to 29.2%;area of green spaces decreased from 27.4% to 20.4%;water area decreased from 26.1% to 23.7%;construction land area increased from 13.8% to 26.8%,and replaced the dominant status of farmland.B.There were 99 366 landscape patches in the study area by 2001,which was almost twice as much as 52 832 landscape patches in 1993.C.Urbanization and increasing human interventions led to the increase of landscape diversity indexes,and the aggravated fragmentation.Through analyzing dynamic changes of urban landscape structures in Tianjin City,evolution trend of the structural characteristics of urban spaces and its factors can be better understood,city pattern and land use properly planned,benign development of economy,society and eco-environment realized.
