Land use regionalization of rural settlements in China.

This paper compartmentalizes regional land use of rural settlements in China by employing a hierarchical clustering method. The statistic data are sourced from the National Bureau of Statistics of China (NBSC) and the data of land use change from the Ministry of Land and Resources of China (MLRC). The population of rural settlement decreases from the southeast to the northwest of China and the density of rural settlement decreases from the east to the west of China. Land-use scale of rural settlement, the proportion of one-storey houses and the average household area decrease from the north to the south of China. The ratio of area of cultivated land to rural settlement is high in the northeast and southwest of China but low in the southeast of China. The land use regionalization of rural settlement can be divided into four regions, namely: the northern region of China, Qinghai-Tibet, Yunnan-Guizhou, and the middle and eastern region of China. The northern region of China and the middle and eastern region of China can be further divided into nine sub-regions: Xinjiang, Northeast China, Ningxia and Inner Mongolia, North China, the south of the Changjiang (Yantze) River and Sichuan Basin, Jiangsu-Shanghai, South China, the Loess Plateau, and Guangxi. In consideration of the significant regional differences, it is proposed that different policies should be implemented regarding the utilization and management of rural settlements.
