- Abstract:
- With the application of RS and GIS techniques,as well as the CBERS data,fractal theory was employed to study circumstances of the fractal of oasis land cover in Tsagan Us Oasis in Dulan county in Caidam Basin,and the prominence of the difference of fragmentation distribution was analyzed.The results show that the biggest landscape separation index in the research area is the forest land and the smallest is farmland,which shows that the scattered degree of farmland is the least and the land use of farmland is the biggest.The biggest regional landscape fragmentation is the forest land,the smallest are waste-grassland and riverbed and water conservancy facilities land,which shows that the dividing degree of forest land is the biggest and the land use of waste-grassland and riverbed and water conservancy facilities land are the least.The biggest index of fractal dimensions is riverbed and water conservancy facilities land,the least is farmland.It means that the shape of riverbed and water conservancy facilities land is irregular,the human disturbance is the least,otherwise the shape of farm land is regular and human disturbance is the biggest.
