非常感谢!!!!

In this paper, by using the TM remote sensing images in 1991 and 2005 as the basic information source, according to the theory of landscape ecology, landscape pattern index, dynamic variation of landscape pattern of 3.3 analysis and in the study area using FRAGSTATS and its driving force. The results show that, in 1991 the changes of landscape pattern in the study area south of Hangzhou Bay area -2005 is more intense, during the period of construction land increased greatly, while the mudflat and forestland, showing a decreasing trend, the landscape fragmentation increased, evenness decreased. The disturbance of human activities on landscape type distribution of intensity increases, the distribution of landscape types in the study area is more widely. The increase of population, economic development, climate and hydrological factors are the main driving force for the evolution of landscape pattern of Hangzhou Bay area. By the end of the atmospheric environment, water environment and biodiversity research, you can see the ecological effects of this change in landscape pattern of the study area is negative.
