广西北部湾经济区土地资源利用与经济增长脱钩分析

目的]分析广西北部湾区域经济增长与土地资源利用的脱钩关系,揭示二者脱钩程度的空间演变规律,为实现区域经济增长与土地资源利用协调发展提供科学依据。方法]应用Tapio脱钩模型对广西北部湾经济区2007—2016年土地资源利用与经济发展脱钩程度、时序演变和空间发展规律进行定量评价和综合分析。结果]广西北部湾经济区土地利用与经济增长基本处于脱钩状态,且有由弱脱钩向强脱钩转化的趋势。从产业类型上看,第一产业GDP与耕地以强脱钩为主且伴有弱脱钩和扩张性耦合状态;第一产业GDP与林地以弱脱钩为主且有向强脱钩转化的趋势;第二、三产业GDP与建设用地始终处于弱脱钩状态。结论]广西北部湾经济区土地利用与经济增长永续脱钩的实现,不仅要继续优化产业结构,还应立足全局和区域协调发展,继续重视国土空间优化,并通过提高海洋资源综合开发能力,全面建设生态空间,实现经济增长和土地利用的协调发展。

Decoupling Between Land Resource Utilization and Economic Growth in Beibu Gulf Economic Zone of Guangxi Zhuang Autonomous Region

Objective] The decoupling relationship between regional economic growth and land resource utilization in Beibu Gulf economic zone of Guangxi Zhuang Autonomous Region was analyzed to reveal the spatial evolution law of the decoupling degree, in order to provide a scientific basis for the coordinated development of regional economic growth and land resource utilization.Methods] The Tapio decoupling model was used to quantitatively evaluate and comprehensively analyze the decoupling degree and the spatial-temporal evolution of land resource utilization and economic growth in the economic zone from 2007 to 2016.Results] The land use and economic growth in Beibu Gulf economic zone were basically in a state of decoupled, and there was a trend from weak decoupling to strong decoupling. From the perspective of industrial type, the primary industry GDP and cultivated land were mainly strong decoupling and accompanied by weak decoupling and expansion coupling. The primary industry GDP and forest land were mainly weak decoupling and showed a trend from weak to strong decoupling. The second and third Industry GDP were always in a weak decoupling state with the construction land.Conclusion] To realize the sustainable decoupling of land use and economic growth in Beibu Gulf economic zone, we should not only continue to optimize the industrial structure, but also focus on the optimization of land space from the perspective of global and regional coordination development, and comprehensively build ecological space, achieve the coordinated development of economic growth and land use by improving the comprehensive development capacity of marine resources.
