摘要
在对传统人口压力指标体系评述的基础上,将无形资源纳入人口压力指标体系,用人口自然增长率、人口密度、人均GDP、初高中在校人数百分比、性别结构、人口年龄结构等指标构建衡量人口压力的指标体系;运用层次分析法计算确定各承压因子的权重,探讨定量研究人口压力的方法和步骤;并以2006年西安市统计资料为依据,在ArcGIS 9.0平台上对西安市13个县级行政区划单位的人口压力进行赋值、量化、分级。结果发现:首先,西安市人口压力最大的地区是碑林区,最小的是阎良区。其次,西安市人口压力等级值接近正态分布,中间等级居多,占64.54%,总体人口压力等级中。再次,西安市经济欠发达地区人口压力一般较大,经济相对发达地区的人口压力一般较小。
On the basis of a literature review of population pressure,the intangible resource was put into the evaluation index system of population pressure,including eleven indexes such as the natural increase rate of population,population density,the average gross domestic product per person,the percentage of population in high school,the sex structure,the population age structure and so on.This paper adopts AHP method to determine the weight of population pressure factors and seeks methods and models that can evaluate population pressure quantitatively.Finally,the gross index of population pressure of 13 counties in Xi＇an was calculated,classified and expressed with the platform of ArcGIS 9.0 with statistical data from the Xi＇an yearbook of 2006.The research has reached the following findings： First of all,the largest population pressure region is Beilin District in Xi＇an,the smallest is Yanliang District.Second,the population pressure levels are close to normal distribution.And mostly are middle levels,accounting for 64.54 percent.The overall grade of
