摘要

Combining the integrated technology of ecological quantity analytical method with GIS technology, based on the Landsat TM images and SPOT images in 1995 and 2009, this paper made a quantitative analysis of the changing process of land use/cover. The results showed that land use/cover in study area had undergone obviously changes from 1995 to 2009. The artificial landscapes which were mainly tropical crops plantation increased dramatically, natural forest and rubber forest was substantially reduced. The major patterns of land use change in the study area were the conversions of the natural forest and rubber forest to tropical crops plantation and cultivated land, cultivated land converted to tropical crops plantation and residential area. The analysis of landscape index showed that the role of landscape structure more diverse and uniform with the diversity of landscape fragmentation increases, the dominance of natural forest and rubber forest on the overall control of landscape reduced under the influence of human activities in the study area. The driving force analysis showed that economic development, agriculture industrial structure, policy and technology factors were the dominant factors of land use/change in the study area in the short term.
