基于共生理论的兵团与地方城市“三生”功能跨界整合发展研究

基于共生理论,选取乌鲁木齐市、五家渠市、昌吉市为研究案例区,构建"三生"空间评价指标体系及"三生"功能评价指标体系,探讨乌五昌地区"三生"空间时空分异格局,借助共生度模型,识别兵团城市与地方城市"三生"功能共生发展模式,并对兵地城市跨界融合发展提供理论建议。结果表明：（1）研究区生产和生活空间面积呈上升趋势,生态空间面积呈下降趋势。（2）在生产功能方面,五家渠市与乌鲁木齐市、昌吉市共生模式分别为正向非对称共生、反向非对称共生,生活功能与生态功能方面,均为正向非对称共生,各功能城市间影响程度不同。（3）基于"三生"空间格局及"三生"功能共生模式,提出兵地融合发展建议,生产方面建立四区,三轴,一基地,生活方面加强交通路网建设,生态方面兵地协同建立生态保护区。

Cross-border integration of Production-Living-Ecological function in XPCC and local city based on Symbiosis Theory

Xinjiang Uygur Autonomous Region is one of the most special regions of China''s administrative divisions. It is composed of two provincial units, autonomous region and Xinjiang Production and Construction Corps (XPCC), which carry out production and operation activities within their respective jurisdiction, resulting in unreasonable industrial distribution and waste of resources between the XPCC and local areas, thus affecting the economic and social development of Xinjiang to a certain extent. Based on the Symbiosis Theory and take the integration of XPCC and local as the ultimate goal. The study area include Urumqi (local city), Wujiaqu (XPCC city) and Changji (local city). With the help of land use data, we constructed indicator system to explore the spatio-temporal differentiation pattern of Production-Living-Ecological. And Symbiotic Degree Model was used to identify Production-Living-Ecological function symbiotic development pattern, aim to provide theoretical suggestions for the cross-border integrated development of XPCC city and local city. The results show that: (1) from the characteristics of spatio-temporal differentiation of Production-Living-Ecological in 2013-2018, the production land in the study area is mainly concentrated in the oasis area, which is in the middle of the study area. Different levels of land area show different trends of increase or decrease. The areas of living land showing high density in middle and low density on surrounding spatial pattern and expanded continuously. The ecological land is mainly distributed in the south of the study area, and the overall trend is decreasing. (2) In terms of production function, the symbiotic model of Wujiaqu city, Urumqi city and Changji city are positively asymmetric symbiotic and negatively asymmetric symbiotic, respectively. Among which, Wujiaqu city has a greater influence on Urumqi city, Changji city has a greater influence on Wujiaqu city. In the aspect of living function, the symbiotic model between Wujiaqu city and the two local cities are positively asymmetric symbiotic, and the two local cities are in a strong influence on each other by virtue of their better urban construction. In terms of ecological function, the symbiotic model between Wujiaqu city and the two local cities are positively asymmetric symbiotic. In the degree of mutual influence, Wujiaqu has a great influence on Urumqi, and Wujiaqu has a great influence on Changji. (3) Based on the spatio-temporal pattern of Production-Living-Ecological and the symbiotic model of Production-Living-Ecological function, we put forward suggestions for the integration and development of XPCC and local city in the production, living, and ecological aspects.
