摘要
依据1978-2008年间的农业人口统计资料,结合1:100万中国土地利用分布图,在ArcGIS9.2软件支持下,运用空间统计分析方法,以中国31个省级行政区为分析单元,分析和探讨了近30年来中国农业人口空间分布格局变化和驱动因素。结果表明:中国农业人口空间分布不连续,地区之间差异显著。自然条件、国家政策和社会经济水平与中国农业人口空间格局时空变化紧密相关。良好的自然条件是农业人口分布的基础条件,地区经济水平发展是促进农业人口空间格局分布的主要因素,国家人口政策调控与农业人口变化直接相关。
Based on agricultural population statistics during the period from 1978 to 2008,combined 1:1000000 land utilization map in China,with ArcGIS9.2 software supported,space statistical analysis method with 31 provinces as the basic unit of spatial analysis can be used to analyze and discuss the agricultural population spatial distribution and driving factors in the last 30 years in China.The results show that spatial agricultural population distribution is discrete in China,and the difference is notable for various places,which is affected by many factors,such as natural conditions,social economic development,national policies and so on.The spatial pattern of natural environment is the elementary condition,while economic development is the main factor to affect the spatial distribution of agricultural population.The governmental policies have direct relationship with agricultural population distribution,too.
