【摘要】：文章引入"生态位"概念,通过构造地区人口生态位指标体系,对我国地区人口生态位进行综合评价,并分析了地区人口生态位与地区人口流入、流出和净流入的关系。人口生态位综合评价结果表明,我国省际人口生态位差异大,北京、上海和天津等沿海发达省市人口生态位较内陆省市高很多,人口由生态位低的地区向生态位高的地区流动;分地区偏最小二乘回归模型则表明人口跨地区流动的影响因素存在差异,经济和知识技能子生态位仍是引起人口流动的最主要原因,但并不能很好解释所有地区,说明人口与经济、社会、资源和环境等人口生态之间是复杂动态系统关系,且影响人口流动的因素也因地区和时间而不同。
[Abstract]:This paper introduces the concept of "niche", through the construction of regional population niche index system, comprehensive evaluation of population ecological regions in China, and analyzes the population niche and areas of inflow, outflow and net inflow of population niche relationship. The comprehensive evaluation results show that China's regional population niche differences, Beijing, Shanghai and Tianjin and other coastal provinces population niche is much higher in inland provinces, population from areas of low niche to niche areas of high flow region; partial least squares regression model shows that factors influencing the population flow across regions are different, economic and intellectual skills sub niche is still the main cause the flow of population, but cannot explain all that area, population and economy, society, resources and environment between the population ecology is a complex dynamic system, and the impact of population flow The factors of movement are also different by region and time.
