【摘要】：广西北部湾经济区的开放开发,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土地利用效率的演变及区域差异,对于提高广西北部湾经济区土地利用效率水平,促进区域的可持续发展有着重要的意义。基于2004—2014年广西北部湾24个县(区)土地利用投入产出数据,运用超效率DEA模型对北部湾区域土地利用效率进行测度,运用探索性空间数据分析(ESDA)方法,对广西北部湾经济区整体和局部的土地利用效率的时空演变格局进行初步分析。结果表明,2004—2014年北部湾经济区土地利用效率总体呈现逐年上升趋势,土地利用效率较高的区域有青秀区、兴宁区、港口区等;广西北部湾经济区土地利用效率存在显著的空间自相关性,从整体上显示各县(区、市)土地利用效率差异有缩小的趋势;从局部看,随着时间的推移"高-高"和"低-低"区域增加,各县(区、市)的空间联系增强。
[Abstract]:The opening and development of Guangxi Beibu Gulf Economic Zone, inevitably associated with the use of land resources, quantitative analysis and identification of land use change and regional difference of efficiency scientifically, to improve the efficiency of land use in Guangxi Beibu Gulf Economic Zone, it has important significance to promote regional sustainable development. From 2004 to 2014 in the northern Gulf of Guangxi 24 a county (District) land use based on input-output data, using super efficiency DEA model to measure the efficiency of land use in Beibu Gulf region, using exploratory spatial data analysis (ESDA) method, a preliminary analysis of the Guangxi Beibu Gulf Economic Zone and the land use efficiency of the local spatio-temporal evolution pattern. The results show that: 2004 in 2014, the Beibu Gulf Economic Zone overall land use efficiency is rising year by year, the regional land use efficiency was higher in Xingning District, green District, north of Guangxi port area; There is a significant spatial autocorrelation between land use efficiency in the Gulf Economic Zone, which shows that the difference of land use efficiency in counties (cities and municipalities) has a narrowing trend. From a local perspective, with the passage of time, the "high high" and "low low" regions increase, and the spatial connections among counties (districts and cities) increase.
