农村居民点用地混合利用对乡村活力的影响:基于山东省的实证研究

Impacts of mixed use of rural residential land on rural vitality:An empirical study of Shandong Province

土地混合利用是提高土地利用集约度、激发地区活力的重要途径。本研究构建了农村居民点用地混合利用与乡村活力关系的分析框架,并以山东省为例,运用辛普森多样化指数、多因素综合评价法、相关性检验等探究农村居民点用地混合利用对乡村活力的影响。结果表明:2010—2018年山东农村居民点用地混合利用指数增速高、中、低区(县)的乡村活力指数增速分别为84.70%、60.74%、50.33%,农村居民点用地混合利用增速越快,乡村活力发展越快;2010年山东农村居民点用地混合利用程度低、中、高区(县)的乡村活力指数分别为0.13、0.23、0.29,2018年分别为0.19、0.24、0.38,农村居民点用地混合利用程度越高,乡村活力水平越高;Spearman相关性分析和Kruskal-Wallis检验结果表明,农村居民点用地混合利用程度与乡村活力显著相关,且对乡村活力具有激发作用。研究认为,农村居民点用地混合利用是激发乡村活力的有效途径,这为编制村庄规划、助推乡村振兴提供新思路。

Mixed land use is an important step to realize intensive land use and to stimulate regional vitality.This study examined the theory of mixed land use,constructed an analytical framework for the relationship between mixed use of rural residential land and rural vitality,and explored the characteristics of the impact of mixed use of rural residential land on rural vitality using Simpson′s diversity index,a multi-factor comprehensive evaluation method,and a correlation test of Shandong Province as an example.The results showed that the growth rates of rural vitality indexes in the high,medium,and low zones of mixed use of rural residential land in Shandong Province from 2010 to 2018 were 84.70%,60.74%,and 50.33%,respectively.Thus,the faster the mixed use of rural residential land improved,the faster the development of rural vitality.The regional averages of the rural vitality index in the low,medium,and high zones of rural mixed use of residential land in Shandong Province were 0.13,0.23,and 0.29 in 2010,respectively,and 0.19,0.24,and 0.38 in 2018,respectively.The higher the degree of mixed use of rural settlement land,the higher the level of rural vitality.The Spearman correlation analysis and Kruskal-Wallis test results showed that the mixed use of rural residential land was related to rural vitality and stimulated rural vitality.This study concludes that mixed use of rural residential land promotes rural vitality and provides new ideas for innovative village planning and rural revitalization.
