乡村三生空间功能耦合协调关系及驱动因素分析

选择原中央苏区核心区域的福建省龙岩市作为研究对象,在定量识别乡村三生空间功能的基础上,利用耦合协调、趋势分析和地理探测器模型,对2012年、2014年、2016年、2018年龙岩市乡村三生空间功能耦合协调关系进行具体分析,探讨乡村三生空间功能耦合协调时空演化发展特征及耦合协调差异的驱动因素.研究结果表明:龙岩市乡村三生空间功能呈“高耦合,低协调”状态,耦合度和耦合协调度发展不均衡,空间分布较为分散;影响耦合协调关系的主要驱动因素是森林覆盖率和农作物播种比例;随着时间的演变,区域的生态因素对乡村三生空间功能耦合协调度的影响逐渐增强.

Coupling Coordination Relationship and Driving Factor Analysis of Rural Production-Living-Ecological Space Function

Selected Longyan City, Fujian Province, which was the core area of the former Central Soviet Area, as the research area, based on the quantitative identification of the spatial function of rural production-living-ecological space, the coupling coordination relationship of rural production-living-ecological space function in Longyan City in 2012, 2014, 2016 and 2018 were analyzed by using coupling coordination, trend analysis and geodetector model. The spatial and temporal evolution characteristics of rural production-living-ecological space’s spatial coupling coordination and the driving factors of coupling coordination differences were discussed. The research results showed that the rural production-living-ecological space function in Longyan City was in a state of “high coupling, low coordination”, the development of coupling degree and coupling coordination degree were unbalanced, and the spatial distribution was relatively scattered. The main driving factorsaffecting the coupling and coordination relationship were forest coverage and crop sowing proportion. With the evolution of time, the influence of regional ecological factors on the coupling coordination degree of rural production-living-ecological space function was gradually strengthened.
