- Abstract:
-
Chongqing is a typical mountainous area in southwest China. Utility systems including land ticket, requisition-compensation balance, connection between the increase of rural construction land and the decrease of urban construction land, are influencing the land use and man-land relationship of Chongqing. This paper takes Shizhu County of Chongqing as an example. This study analyzed spatial distribution characteristic of cultivated land based on change investigation database of Shizhu County land use in 2011 and MPI of landscape metrics. The Origin software was used to fit the function. This paper identified how the residential areas, roads, rural roads and rivers influence the cultivated land. It also combined with terrain niche index and distribution index to study the terrain how to affect cultivated land. The results show that cultivated land in Shizhu of Chongqing generally presents aggregated distribution pattern. Residential areas, roads, rural roads and waters impact the spatial distribution of cultivated land at different degrees. The influence degree and mechanism of these factors are different. The influence of residential areas, rural roads and waters on cultivated land belongs to type of high effect on a small scale, but the effect of the road is low on a large scale. Terrain factor restricts the spatial distribution of cultivated land so that cultivated land mainly distributes in the slope areas with 0~25° and areas with elevation of 100~1 200 m. Besides, most cultivated land distributes in the area with low elevation and slope. This paper aims to provide reference to choose the area of land development, consolidation and reclamation in southwest China. This study also can provide research idea and method to study the location of land development and consolidation.
