农村发展系统特征及其空间格局分异,是确立区域农村可持续发展模式的重要依据.该研究着眼于县域尺度,利用均方差权值评价法、系统耦合理论、探索性空间数据分析、空间变差函数等方法,从系统总体状态、子系统间的耦合关系、系统的空间格局分异与规律等角度探讨三峡库区农村发展系统特征及规律.结果表明,三峡库区19个区县属于中度协调、基本协调、轻度失调、中度失调4类之中,区县之间系统协调度差异不大;农村发展总系统以及社会系统、经济系统、资源环境系统3个子系统在空间整体上都呈现空间正相关特性,发展水平相似的区域分别集聚分布;农村发展总系统以及社会系统、经济系统、资源环境系统3个子系统由空间自相关引起的结构化分异十分显著,空间自组织性较强.该研究结果可为政府部门制定跨区域统筹发展战略,完善农村发展政策提供参考依据.

The systemic characteristic and spatial pattern of rural development are important basis for establishing mode of regional sustainable development. The evaluation system composed of 16 indicators which belong to social system, economic system and resource-environmental system is established to evaluate rural development status. At present, the study on regional rural development mainly focuses on spatial pattern, but the study on spatial correlation is seldom. The systemic characteristic and spatial pattern of rural development on regional scale (counties) in Three Gorges Reservoir Area were investigated using mean-squared deviation weight method, system coupling theory, exploratory spatial data analysis method (ESDA), variogram model and so on, and discipline of rural development via the master systemic status, the relationships of subsystems and spatial correlation of system were explored. Conclusions are drawn as follows:1) The rural development level in Three Gorges Reservoir Area is quite unbalanced, and the high-level counties in regional scale mainly locate in the area around Chongqing’s main urban area, the correspondingly low-level counties mainly locate in eastern Chongqing. The disparity of economic system among subsystems is the highest, followed by social system and resource-environmental system. 2) The overall level of coordination degree between subsystems is still low in Three Gorges Reservoir Area. Coordination degrees of 19 counties mainly are divided into four kinds, the moderate coordination, the mild coordination, the mild incoordination and the moderate incoordination, and there are no obvious differences among these counties. On regional scale, the counties with high-level coordination degree mainly locate in the north of Three Gorges Reservoir Area, and the correspondingly low-level counties mainly locate in the south. 3) The overall of rural development system and its subsystems (e.g. social system, economic system and resource-environmental system) of 19 counties exhibit the high spatial positive correlation, and the similar level of counties are clustered. Intriguingly, social system and economic system have the similar clustered pattern on regional scale. This may be due to the fact that social development always coexists with economic development. 4) The structural differences of rural development system and its subsystems caused by spatial positive auto-correlation are significant, and it demonstrates a strong spatial auto-organized ability. It shows that although the self-development is the key factor for rural development, the rural development status of a county not only depends on itself, but also the other surrounding counties. Among subsystems, resource-environmental system has the strongest auto-organized ability, while economic system has the weakest ability. The range of the spatial correlation influence of resource-environmental system is most wide. In general, the research results provide a helpful reference for government to make regional strategic decisions and improve rural development policies. More attention should be directed at those counties that locate in the low-low level cluster regions. In regional scale, rural development in Three Gorges Reservoir Area should aim at promoting harmonious development among regions in the future. And internally, disordered development should be controlled and rationalized through planning measures to achieve harmonious development among social system, economic system and resource-environmental system.
