在中国1km×1km栅格尺度人居环境自然适宜性分类评价和分县尺度人口空间集聚程度分级评价的基础上,结合中国分县资源环境承载力和区域经济发展水平和发展潜力,确立了中国可持续的人居功能分区评价模型,提出了中国可持续发展的人居功能分区方案。研究表明:中国可持续的人居功能分区空间分布呈现东南半壁优于西北半壁的格局;人居功能强可持续地区面积约139.75×104km2,占国土面积的14.66%,相应人口4.3亿,接近总人口的1/3,主要分布在东南沿海、长江中下游地区、四川盆地、黄淮海平原以及东北平原的部分地区;人居功能较强可持续地区面积约193.61×104km2,占国土面积的1/5,相应人口3.2亿,接近总人口的1/4,主要分布在三江平原、辽河平原、山东半岛等地;可持续地区面积210.19×104km2,约占国土面积的22%,相应人口3.7亿,占总人口的28.24%,主要分布在呼伦贝尔高原、黄土高原和云贵高原等地,零星见于藏东南谷地和柴达木盆地等地区;较弱可持续地区,面积约145.85×104km2,占国土面积的15.30%,人口1.4亿,约占总人口的11%,零散分布于黄土高原、川滇高原和云贵高原的部分地区;弱可持续地区面积约263.86×104km2,约占国土面积的27.68%,相应人口0.4亿,接近总人口的3%,主要分布在青藏高原、西北荒漠以及川滇高原北部地区。
Based on the classification and evaluation of natural suitability of human settlements in 1km × 1km grid scale in China and the hierarchical appraisal of spatial agglomeration of population in different scales in county, combined with the bearing capacity of resources and environment, the level of economic development and the potential of regional economy in China, Sustainable Habitat Functional Zoning Evaluation Model, put forward China’s sustainable development of Habitat Functional Zoning Program. The results show that the spatial distribution of sustainable human settlements in China shows the pattern that the southeast half of the wall is better than the northwest half of the wall. The area with strong and sustainable human settlements is about 139.75 × 104km2, accounting for 14.66% of the total area of the country, with a population of 430 million, One-third of the population is mainly distributed in the southeast coast, the middle and lower reaches of the Yangtze River, the Sichuan Basin, the Huang-Huai-Hai Plain and parts of the Northeast Plains. The area with strong and sustainable human settlements is about 193.61 × 104km2, accounting for 1 / 5, the corresponding population of 320 million, close to 1/4 of the total population, mainly in the Sanjiang Plain, Liaohe Plain, Shandong Peninsula and other places; sustainable area 210.19 × 104km2, accounting for about 22% of land area, the corresponding population of 370 million, Accounting for 28.24% of the total population, mainly distributed in the Hulunbeier Plateau, the Loess Plateau and the Yunnan-Guizhou Plateau, sporadically found in the southeastern Tibet and Qaidam basins; weaker and sustainable areas, an area of about 145.85 × 104km2, accounting for land area 15.30%, population 140 million, accounting for about 11% of the total population, sporadically distributed in parts of the Loess Plateau, Sichuan-Yunnan Plateau and the Yunnan-Guizhou Plateau; weak sustainable area of about 263.86 × 104km2, accounting for about 27% of the land area .68%, corresponding population of 400000000, close to 3% of the total population, mainly in the Qinghai-Tibet Plateau, the desert in the northwest and northern Sichuan-Yunnan Plateau.
