| Abstract: |
| Measuring land use transformation in multi dimensional and multi sequence regions and revealing the characteristics and dynamic mechanism of land use transformation are important basis for regional land planning and regulation. Based on GIS spatial analysis, land use exchange change rate and spatial separation degree, this paper studied the temporal and spatial characteristics of land use transformation in various time periods of western Guangxi resource enrichment area from 1995 to 2015. The results were showed as follows. ①At the beginning of the research, the main manifestation was the mutual conversion between agricultural land. In the later stage, the types of land use transformation were complex and diverse, and the area of construction land increased significantly compared with the initial stage of research. ②The intensity of land use transformation shifted from the north to the south with time. The geographical distribution of land use transfer intensity and the type of transfer varied in different periods. ③The average spatial separation degree of land use transformation at the beginning and end of the study period was larger than that in the middle period.④Land use transformation was related to geographical location, topography, mineral exploitation and processing, population transfer, labor composition, and national policies. In a short period of time, resource based areas are strongly interfered by human activities, and land use transformation is active. The analysis of their transformation characteristics is of great significance for the overall coordination of regional land resources development, utilization and protection. |
