【摘要】：人口是区域经济活动的主体,是区域发展最活跃的因素,研究区域人口分布及其变化对于区域分析与规划具有重要意义。人口集聚度是评价区域人口集聚程度的复合指标,由人口密度和人口流动强度两个要素构成,能够综合反映区域人口集聚的过程及趋势,与传统测度指标相比,具有更丰富的理论内涵与实践意义。资源富集区大多资源丰富而经济欠发达,生态环境脆弱,对人类活动十分敏感。彬长旬地区煤炭资源储量丰富,是陕西省重要的能源化工基地,近年来由于资源开发带动经济高速增长,人口集聚度变化显著。选择彬长旬资源富集区作为研究对象,分析其资源开发前后的人口集聚度变化情况,探讨资源开发与人口集聚度变化的关系,对于促进资源富集区人口的合理再分布,实现区域人口、经济与资源环境的协调和持续发展具有重要意义。本文从人口集聚度的内涵与地理意义入手,分析了资源开发与人口集聚度变化的关系,改进了人口集聚度的测度方法,以彬长旬资源富集区作为实证对象,基于最新的人口普查数据,对2000年和2010年该地区各乡镇的人口集聚度及其变化情况进行综合评价,分析了资源开发等因素对其变化产生的影响,根据评价结果预测其人口集聚趋势,并提出相关对策建议。本文得到的主要结论如下： (1)从总体上看,2000-2010年彬长旬地区人口集聚度变化较大,人口流动强度显著提高,但人口密度变化不大,人口集中程度增大；从局部来看,人口流动强度和人口集聚度格局变化与资源开发活动具有很强的时空一致性,人口集聚度与人口流动强度变化大的乡镇基本上都是煤炭资源重点开发的区域,而在由于资源枯竭导致煤炭产量下降的乡镇,人口集聚度和人口流动强度大幅度下降。 (2)资源开发是影响彬长旬地区人口集聚度变化的主导因素,直接影响区域人口流动强度变化；农村劳动力转移是导致大部分乡镇人口密度下降的主要原因,这与资源开发对区域经济的影响有直接关系；城镇化是导致县域中心镇人口集聚度大幅度上升的主要原因,但其他乡镇人口集聚能力较弱。 (3)未来彬长旬地区人口将以集聚为主要趋势,不断向县域中心镇和资源开发活动加强的城镇集聚,要以空间功能区的思想和原则为指导,通过在城镇化地区、农业地区和生态地区实行不同的产业政策和人口政策,对资源开发和人口集聚进行优化调控,以促进资源富集区的可持续发展。
[Abstract]:Population is the main body of regional economic activity, it is the most active factor in regional development, and it is of great significance to study regional population distribution and its change to regional analysis and planning. Population concentration is a composite index to evaluate the degree of population concentration in the region. It is composed of two elements of population density and population flow intensity. It can reflect the process and trend of regional population aggregation comprehensively. Compared with traditional measure index, it has more theoretical connotation and practical significance. Most of the resource-rich areas are rich in resources, underdeveloped in economy, fragile in ecological environment and very important for human activities. Sensitive. The reserves of coal resources in Shiten area are abundant, and it is an important energy chemical base in Shaanxi Province. In recent years, due to the development of resources, economic growth and population concentration change have been driven by the development of resources. In order to promote the rational redistribution of the population of the resource-rich region, we can realize the rational redistribution of the population of the resource-rich region. The coordination and sustainable development of population, economy and resource environment are of great importance This paper starts with the connotation and the geographical meaning of the population concentration degree, analyzes the relation between resource development and population concentration change, improves the measure method of the population concentration degree, Based on the survey data, the population concentration and the change of population in each township in 2000 and 2010 are comprehensively evaluated. The influence of factors such as resource development on the change of population is analyzed, and the trend of population aggregation is predicted according to the evaluation results, and the phases are put forward. Recommendation for closing countermeasures. This article has to The main conclusions are as follows: (1) In general, the population concentration change is large in the period 2000-2010, the population flow intensity is remarkably improved, but the population density change is not large, and the population set In terms of local view, the change of population flow intensity and population concentration pattern and resource development activities have very strong space-time consistency, and the towns with large population concentration and population flow intensity change are basically the areas of key development of coal resources, and are exhausted due to resource depletion Township, population gathering, and (2) Resource development is the leading factor that affects the change of population concentration in Shiten area, which directly affects the change of population flow intensity in the region, and the transfer of rural labor force is the result of large proportion. The main reason for the decline of population density in sub-towns is the direct relationship between the development of resources and the influence of resource exploitation on regional economy; urbanization is the main reason leading to a large increase in the concentration of population in the central town of county. However, the population gathering capacity of other towns is weak. (3) In the future, the population of the ten-year-old area will be concentrated as the main trend, and the urban agglomeration strengthened by the county central town and the resource development activities will be continuously increased, so as to take the space function area Guided by the thought and principles, through the introduction of different industrial policies and population policies in the areas of urbanization, agricultural regions and ecological regions, resource development and population agglomeration are optimized.
