Abstract:

The spatial distribution of reserve available construction land overlaps with that of reserve available cultivated land in the resources and environmental carrying capacity and territorial development suitability evaluations of current territorial spatial planning. On the basis of elaborating the connotation of relevant concept, this study developed an integrated evaluation method of reserve available land resources, discussed the regional tendency of use of these two types of land, and took Jiexiu City in Shanxi Province as an example. The results are as follows: 1) Reserve available construction land in Jiexiu City had an area of 45.3 km 2, which was 6.1% of the total land area of the city. Its distribution was scattered. The reserve available construction land could be generally divided into three levels: highly suitable, suitable, and less suitable. The corresponding areas were 3.6 km 2, 16.1 km 2, and 25.6 km 2 respectively. The area of reserve available construction land per capita was 0.16 mu. 2) The area of the reserve available cultivated land was 74.1 km 2, which was 10% of the total. The reserve available cultivated land also could be divided into three levels: highly suitable, suitable, and less suitable. The corresponding areas were 21.7 km 2, 26.1 km 2, and 26.3 km 2respectively. The area of reserve available cultivated land per capita was 0.26 mu. There were similar spatial distributions between these two types of land in the study area. The potential of reserve available land resources in Mianshan and Lianfu towns was large, while the potential of the urban area and its surroundings was small. In view of the overlap and difference of spatial distribution between these two types of land, reserve available land resources in the urban area, town centers, and the northern part of the city could be used as construction land preferentially in the future. They should be classified as urban space. Reserve available land resources in the southern areas of Lianfu, Mianshan, Yitang, and Zhanglan towns could be transformed into new cultivated land. They should be classified as agricultural space.

Key words: reserve available land resources, reserve available construction land, reserve available cultivated land, territorial spatial planning, three types of territorial spaces, Jiexiu City
