县域农村居民点空心化程度评价及其空间布局优化

Degree of Hollowing of Rural Residential Sites at County Scale:Evaluation and Its Spatial Layout Optimization

对农村居民点空心化程度进行评价并优化其空间布局,可以有效整合土地资源,推进城镇化进程有序发展。选取黑龙江省明水县为研究对象,采用空心化程度评价指数对研究区空心化现状进行评价,并揭示农村居民点整理时序,最后提出整理方案。结果表明,明水县空心村状况显著,在不同的规划期限,各乡镇表现出的空心化趋势不尽相同,整理比重较大的乡镇有通泉乡、永兴镇等。最后,根据研究结果提出空间布局优化方案,依据规划期限,给出迁移农村居民点及迁移方向。基于以上研究结果,未来将结合各农村居民点的地理因素、社会经济发展因素、土地开发利用等实际情况给出合理的发展建议。

The paper aims to evaluate the degree of hollowing of rural residential sites,and optimize its spatial layout,which is of great importance to effectively integrate land resources so as to promote the orderly development of urbanization process.Taking Mingshui,Heilongjiang as the study object,the author evaluates the hollowing status of study area by adopting the evaluation index of hollowing degree,and reveals the timing of rural residential arrangement,and finally put forward the arrangement plan.The results show that:the hollowing of rural residential sites was obvious in Mingshui,the trend of hollowing in townships is different in different planning periods,the rural settlements have a large proportion of townships are Tongquan,Yongxing and so on;at last,according to the research results,the author puts forward the optimization scheme of spatial layout,and suggests the migration of rural settlements and the migration direction according to the planning period.Based on the above research results,in the future,reasonable development proposals will be given in light of the geographical factors,social and economic development factors,land development and utilization of rural residential sites.
