农村宅基地是农村土地系统中极其重要的组成部分,是农村衰落、农村空心化等各种问题表征的重要载体.农村地区发生巨大变化的同时,农村宅基地也发生着深刻的转型.本研究在总结国内外对于农村宅基地多功能分类的基础上,根据实地调查问卷,从宅基地功能提升的角度划分并界定了宅基地的人口承载功能、资产以及居住功能.通过协调转型度模型对农村宅基地的功能及协调转型度进行了分析.结果表明:(1)2000–2017年鄱阳县农村宅基地功能转型度在整体上有了明显提升.(2)北部山地丘陵区及环鄱阳湖区主要分布着协调转型度的高值区,近县城的平原区主要分布着协调转型度的低值区.(3)区位条件与资源禀赋较好的区域,人口、资本等要素非农化的支撑条件也比较好,相应的非农化趋势也更为明显.应根据不同区域农村宅基地转型的差异化情况提出针对性的发展建议.“,”The rural homestead is a major part of the rural land system, which is an important carrier of various rural issues such as rural decline, rural hollowing and others. Great changes have occurred in China's rural areas, while the rural homestead has also undergone transformation. Based on summarizing the multi-functional classification of homesteads from previous research, this study divided and defined the population bearing function, assets, and residential function of homesteads from the perspective of functional improvement according to the results of a survey questionnaire. Using Poyang County as the case study, this paper analyzed the functional transformation of rural homesteads through the model of coordinated transformation degree. The results demonstrated the following trends. (1) From 2000 to 2017, the transformation degrees of rural homestead functions in Poyang County have obviously improved overall. (2) The high value areas of the transformation degrees were mainly distributed in the northern hilly region and around Poyang Lake, while most of the low value areas were distributed in the plain areas near the county town. (3) In the regions with better location conditions and resource endowments, the basic condi-tions and trend of non-agriculturalization of the population, capital and other factors are more significant. According to the differentiation of rural homestead transformations which occurred in different regions, the government could put forward targeted development suggestions for the future.
