Study On Land Use Change Of Zhejiang Province Based On GIS

The land use/land cover change (LUCC) is the research heat point of geographical circles in recent years. The contradiction between people and land is conspicuous in the developed areas of East China. The study on land dynamic change and their driving forces of the developed areas in the eastern part of China is of great help to protect and reasonably use the limited cultivated land resources. With the development of technology, Remote Sensing (RS) and Geographic Information System (GIS) used on LUCC are becoming more and more mature. The effective monitor carried out by means of RS and GIS is convenient and time-saving.Firstly, in the support of RS and GIS technology, images of 2000, 2005 and 2008 were employed. According to the human-computer-interaction interpretation, the cultivated land dynamic change database of Zhejiang province between 2000 and 2008 was established. Secondly, with the help of land transition matrix, single 1and use type model and comprehensive 1and use type model, the paper researched the land change of Zhejiang. At last, taking the cultivated land for example, the paper researched the temporal-spatial character in detail and predicted the area of cultivated land in the future by means of the linear regression and Markov method. Meanwhile, the driving forces index of cultivated land change was also studied by using principal components analysis method and ridge regression analysis method.The results showed that the land change of Zhejiang Province was obvious during the study, the dynamic degree of cultivated land between 2000 and 2008 was -1.44%, while the value of forest was -0.1%, the value of grass land was 0.34%, the value of water was 1.52%, the value of residential and residential and industrial land was 10.79%, and the value of unused land was 0.5%. The value of comprehensive 1and use change was 0.271%. To the cultivated land solely, the change was obvious, the dynamic degree of 2000~2005 step was -1.42%, while the dynamic degree of 2005~2008 step was -1.46%, and the population mean value is -1.44%. Most of the changed cultivated land was turned into residential and industrial land. Compared with the 20th century, the new factors, non-agricultural population ratio, real estate development investment, urban green coverage area, together with the traditional orchard area factor, consisted of the main driving forces of cultivated land change of Zhejiang province and even the developed areas of East China in the early 21st century.
