基于GIS技术的典型省际交界区域土地开发适宜评价

Evaluate on the Land Development Suitability in Typical Provincial Boundary Regions Base on GIS

以承接产业转移,促进产业及其用地优化配置为研究背景,选取典型省际交界区域的皖东滁州市,从资源约束、发展引导两大视角,构建土地开发适宜度评价指标体系,运用GIS空间数据挖掘、分析及输出显示等功能,形成90×17面板数据,采用多因子综合评价法与逻辑象限模型,完成滁州市域土地开发适宜度评价,并提出差别化土地利用分区对策。结果表明:重点开发区域范围涉及市县辖区及周边紧邻镇域,集中于区域社会经济发展较好的地区;后备开发区域集中于天长市大部、明光市北部、全椒南部等地区,其他地区也有零星分布;限制开发区域主要分布于定远县及凤阳县的平原地区,以及明光市与来安县交界山地丘陵区域;协调开发区域仅是南谯区及周边乡镇,以及定城镇、炉桥镇与六镇镇等区域。

To undertake the transfer of industry to promote the industry and its optimization of land use configuration as the research background,a typical provincial boundary region in Chuzhou City of eastern Anhui region was selected as an example from two perspectives of resource constraint and development guidance.Land development suitability evaluation index system was constructed by using GIS spatial data mining,analysis,output display and other functions,panel data with 90×17 were formatted.multi-factor comprehensive evaluation method and logic quadrant model were used to complete the Chuzhou domain land development suitability evaluation,and the differentiated land use zoning countermeasures were proposed.The results show that priority development region covering the county area adjacent to town and surrounding area was the regional socio-economic development of better concentrated area;reserve development region focued on most of Tianchang,north Mingguang,south Quanjiao and other regions,other areas of sporadic distribution;restricted development area mainly distributed in Dingyuan and Fengyang plain area,as well as hilly area at the junction,and of Mingguang and Lai′an;coordinately development of region was the only district and the surrounding township,as well as towns including Dingcheng,Louqiang and Liuzhen.
