赣东山地丘陵区土地利用多功能与乡村发展的时空耦合关系

Spatio-temporal coupling relationship between land use multi-functions and rural development level in hilly region of eastern Jiangxi Province

为准确把握土地利用多功能与乡村发展的耦合协调关系,明确二者之间耦合交互作用类型。以江西省万年县为例、村域为研究单元,测度2010—2018年土地利用多功能与乡村发展水平,借助耦合协调模型分析二者关系,并依据耦合作用关系划分乡村类型。结果表明:1)2010—2018年土地利用多功能与乡村发展水平均呈增长趋势,但乡村发展水平增速高于土地利用多功能水平,空间格局特征各异;2)万年县土地利用多功能与乡村发展耦合关系明显,耦合度和协调度随时间推移发生演变,二者在空间上具有一定关联性;3)2010—2018年土地利用多功能与乡村发展水平耦合协调发展主要类型由相互阻碍型转变为促进与阻碍并存型,这与土地利用多功能增速低于乡村发展水平有关。最后,根据土地利用多功能与乡村发展相互作用的3种耦合作用类型,针对性地提出解决措施。

The aims of this study are to accurately grasp the coupling and coordination relationship between land use multi-functions and rural development and clarify the types of coupling and interaction between them.Taking Wannian County,Jiangxi Province as an example and the village area as the research unit,this study measures the land use multi-functions and rural development level from 2010 to 2018,analyzes the relationship between them by using coupling coordination model,and classifies the villages according to the coupling relationship.The results show that:1)From 2010 to 2018,both the land use multi-functions and rural development level show an increasing trend.The growth rate of rural development level is higher than that of land use multi-functions,and their spatial pattern characteristics are different.2)The coupling relationship between land use multi-functions and rural development in Wannian county is obvious.The coupling degree and coordination degree evolve over time,and they are spatially related.3)From 2010 to 2018,the main type of coupling and coordination between land use multi-functions and rural development level changes from mutual obstruction type to promotion and obstruction type,which is related to the fact that the growth rate of land use multi-functions is lower than the level of rural development.Finally,according to the three coupling interaction types between land use multi-functions and rural development,the solutions are put forward.
