The Analysis of Road Networks'Influences on the Changes of Landuse in Fujian Province, China
摘要
Abstract
Based on the changes of landuse in Fujian Province during 2000—2010, this research used the buffer analysis to define the areas impacted by the road networks. Then, the study used the correlation analysis to achieve the relationship between the density of road networks and landuse transformation in the impacted areas under the different scales. Also, the terrain features of landuse conversion were analyzed. Finally, the threshold of road networks’density was achieved. The results showed that road networks’range of influence was 1 000 m, and the road construction in Fujian Province was one of the reasons that caused the following transformations:forest transformation to construction, shrub transformation to construction, wetland transformation to construction, farmland transformation to construction. According to the terrain features of landuse transformation under different scales, the following results were obtained: the transformation from forest to construction happened in the altitude of 230~360 m, the transformation from shrub to construction happened in the altitude of 100~180 m, the transforma-tion from wetland to construction happened in the altitude of 60~100 m, the transformation from farmland to construction happened in the al-titude of 110~200 m, the changes of landuse occurred in the south slope beneath 7o;According to the threshold of road networks’density, the study achieved the following results:the threshold of the transformation from forest to construction was between 1.98 km·km-2 and 2.27 km· km-2, the threshold of the transformation from shrub to construction was between 2.29 km·km-2 and 2.92 km·km-2, the threshold of the trans-formation from wetland to construction was between 2.61 km·km-2 and 3.01 km·km-2, the threshold of the transformation from farmland to construction was between 2.23 km·km-2 and 2.98 km·km-2.关键词
