摘要/Abstract

摘要： 随着中央政府将长江经济带发展提到国家区域战略的新高度，其对建设用地的需求将进一步增加。作为客观反映地区剩余或潜在建设用地对未来人口集聚、工业化和城镇化发展承载能力的指标，后备适宜建设用地潜力成为决定研究区域能否持续稳定发展的关键因素。基于此，本文根据后备适宜建设用地的计算方法和评价技术流程，测算了长江经济带后备适宜建设用地潜力，并对其空间分布特征进行了分析。结果表明：长江经济带后备适宜建设用地面积为85 672.35 km²，约占研究区总面积的4.18%，总体潜力不大，空间上呈现出长江北部高于南部，中游、下游、上游地区依次递减的分布趋势；人均后备适宜建设用地0.22亩/人，下、中、上游地区呈现出依次递减的趋势；四川盆地、两湖平原、皖北等区域的后备适宜建设用地潜力较大，长三角、大城市市辖区以及川西地区不仅后备适宜建设用地较缺乏，人均后备适宜建设用地面积也较低。

Abstract: The central government has identified the construction of the Yangtze River Economic Belt as one of the three national development strategies of China in the new period. On this background, its demand for construction land will increase further. Potential of available construction land can reflect the carrying capacity of surplus construction land for the future population aggregation, industrialization and urbanization in a region. It becomes a key factor that decides whether the study area could keep sustainable and stable development. According to the multifactor algorithm and extracting process of available construction land, this article assessed the amount and spatial distribution characteristics of the potential of available construction land on the Yangtze River Economic Belt. The result found that the construction land had a tendency of increasing first, decreasing then and increasing again in the study area. In 2008, its construction land area reached 10.96×10⁴km² and the land development intensity was 5.35%. For the latter, Districts characterized by the levels of high and very high were distributed in the Yangtze River Delta, Lianghu Plain and Sichuan Basin, etc. Areas featured by the levels of low and very low were distributed in the western Sichuan, Yunnan, Guizhou and so on. Its available construction land potential was 85672.35km², which accounted for 4.18% of the total land area. In general, The total potential was small. It was higher in the north than of the south and decreased gradually in the middle reaches, the lower reaches and the upper reaches of the Yangtze River. The potential of available construction land per capita was 0.015 ha and decreased gradually in the lower reaches, the middle reaches and the upper reaches. The amount of available construction land was relatively abundant in Sichuan Basin, Lianghu Plain and the north of Anhui Province. Potential of available construction land and its per capita area were both small in the Yangtze River Delta, municipal districts of big cities and western Sichuan.

Key words: Yangtze River Economic Belt, construction land, available construction land, available construction land per capita
