【摘要】：国家层面社会经济与城镇化的转型发展及长江经济带的战略推进为三峡库区城镇的健康可持续发展确定了方向。以湖北省秭归县为例,运用生态足迹和生态安全格局方法,从资源消耗和土地安全视角分别对县域和中心城区的适度人口和用地规模进行测算。结果表明:2015年秭归县域适度人口规模为31.03万人,用地规模244.64km~2,预留用地132.26 km~2,而秭归中心城区适度人口规模为21.01万人,用地规模18.91 km~2,预留空间约9.01万人、11.82 km~2,表明秭归县域人口已超出生态限制,且多处于农村,应控制生态资源消耗,加强构建县城—重点镇—基础镇的城镇体系,逐步引导农村人口向秭归城镇体系各节点合理转移。
[Abstract]:The transformation and development of social economy and urbanization at the national level and the strategic advancement of the Yangtze River economic belt set the direction for the healthy and sustainable development of the towns in the three Gorges Reservoir area. Taking Zigui County in Hubei Province as an example, the appropriate population and land use scale of county and central urban area were measured from the perspective of resource consumption and land security by using ecological footprint and ecological security pattern method. The results show that in 2015, the appropriate population scale of Zigui County is 310300 people, the land scale is 244.64kmm2, the reserved land is 132.26 kmm2, and the moderate population scale of Zigui central urban area is 210100 people. The scale of land use is 18.91 km2, and the reserved space is about 90100 people, indicating that the population of Zigui County has exceeded the ecological limit, and most of them are located in rural areas. It is necessary to control the consumption of ecological resources and strengthen the construction of the town system from county to key town to basic town. Gradually guide the rural population to Zigui urban system node rational transfer.
