【摘要】：广西北部湾经济区的经济发展不可避免地伴生着土地资源的利用,科学地分析并定量识别其经济增长与土地利用效率之间的耦合关系,对于高效利用有限的土地资源发展区域经济具有重要的意义。基于耦合理论,选取研究区生产总值、财政收入、第二产业总产值、第三产业总产值、固定资产投资总额5个经济增长指标,选取地均固定资产投资、地均二、三产业从业人数、地均液化石油气供气量、地均供水量、地均供电量、城市人口密度、人均住房建筑面积、人均道路面积、地均GDP、地均二、三产业总产值、建成区绿化覆盖率11个土地利用效率指标,测算广西北部湾经济区2003-2013年间经济增长和土地利用效率的综合发展水平,分析各地级市的经济增长和土地利用效率的耦合关系及协调发展程度,在GIS技术支持下,分析二者协调发展度在空间上的差异。研究结果表明:广西北部湾经济区土地利用效率与经济发展耦合关系处于良好或高水平耦合阶段,但协调发展度整体偏低,即二者处于高耦合低协调的发展水平。6个地级城市中,南宁的经济增长与土地利用效率协调发展度最高,但仍处于勉强协调状态,最差是崇左,处于中度失调状态,其余各市基本处于轻度失调状态。
[Abstract]:The economic development of Guangxi Beibu Gulf Economic Zone is inevitably accompanied by the utilization of land resources. The coupling relationship between economic growth and land use efficiency is scientifically analyzed and quantitatively identified. For the efficient use of limited land resources to develop regional economy has an important significance. Based on the coupling theory, we select five economic growth indexes of GDP, fiscal revenue, gross output value of secondary industry, gross output value of tertiary industry and total investment of fixed assets. The number of employees in the three industries, the average gas supply of liquefied petroleum gas, the average water supply, the average electricity supply, the density of urban population, the per capita housing construction area, the per capita road area, the per capita GDP, the gross output value of the second and third industries, The integrated development level of economic growth and land use efficiency in Guangxi Beibu Gulf Economic Zone from 2003 to 2013 is estimated by 11 land use efficiency indicators of green coverage in the established areas. This paper analyzes the coupling relationship between economic growth and land use efficiency and the degree of coordinated development of each prefectural city. With the support of GIS technology, the spatial difference of the degree of coordinated development between them is analyzed. The results show that the coupling relationship between land use efficiency and economic development in Guangxi Beibu Gulf Economic Zone is at a good or high level, but the degree of coordinated development is on the low side. Among the six prefecture-level cities, Nanning has the highest degree of coordinated development of economic growth and land use efficiency, but it is still in a state of barely coordinated, the worst of which is Chongzuo, which is in a moderate state of maladjustment. The other cities are basically in a state of slight imbalance.
