Applying WUDAPT Product into the Spatial-Temporal Analysis of Land Use Change in the Pearl River Delta Region from 1988 to 2009
Refereed conference paper presented and published in conference proceedings


摘要The Pearl River Delta (PRD) region has experienced significant land use change since the putting forward of reform and opening policy in 1978. This paper analyses the spatial-temporal pattern of land use change in the PRD region with the help of a remote sensing based land use classification method—the World Urban Database and Access Portal Tool (WUDAPT), in the selected year 1988, 1999 and 2009. Land use transformation matrix was used to specify the quantity and transferring direction of each land use type in the PRD region. Moran’ I was used to detect the spatial correlation of different land use types in this region. The results show that the area of urban built-up types is continuously increasing and natural land cover types (such as mixed forest, wetland/ fish pond and water bodies) is decreasing from 1988 to 2009. Moreover, cropland/ grassland, mixed forest and water bodies are the dominate land use types which were converted into urban built-up types in this period. Last but not least, the spatial distribution pattern of land use types has a decreasing gathering trend from 1988 to 2009. This paper also examines that WUDAPT is efficient and effective for analysing land use changing issue.
