摘　　要：利用南充市2014年分区县土地利用数据和社会经济数据,从土地、人口、经济3个方面构建农村空心化水平的测度框架及指标体系,采用熵值法、多指标综合评价法对南充市农村空心化水平进行测度,并利用SPSS 23.0进行相关性和多元线性回归分析,揭示其形成机理.结果表明:1)南充市土地、人口、经济以及综合空心化水平在空间分布上呈现不均衡的态势,主要表现为由顺庆区向外围逐渐减小的特征,并且以中、低等级为主.2)农村空心化水平受多种因素的影响.地均财政收入、农村居民人均纯收入、固定资产投资额、农村常住人口数量、二三产业非农化率以及人均耕地面积的变化是农村空心化的主要影响因素.Based on the land use data and socioeconomic data of Nanchong district county in 2014,the measurement framework and index system of the level of rural hollowing are constructed from 3 aspects of land,population and economy.The entropy method and multiple index comprehensive evaluation method are used to measure the level of the rural hollowing level in Nanchong,and the formation mechanism is revealed by SPSS 23.0 correlation and multiple linear regression analysis.The results show that:1)The spatial distribution of land,population,economy and comprehensive hollowing level in Nanchong is uneven,which is mainly characterized by the gradual decrease of Shunqing District,and mainly in the middle and low grades.2)The level of rural hollowing is influenced by many factors.The main influencing factors are the average financial income,the per capita net income of the rural residents,the investment of the fixed assets,the number of the rural resident population,the non agrochemical rate of the two and three industry,and the change of per capital cultivated land area.
