基于GIS的霍邱县土地适宜性评价与利用对策研究

Research on Land Suitability Evaluation and Utilization Countermeasures in Huoqiu County Based on GIS

科学的评价方法和技术是合理利用有限土地资源的基础,以霍邱县为例,基于GIS空间分析技术,结合层次分析法,建立霍邱县土地适宜性评价指标体系和综合评价模型,对霍邱县土地适宜性进行评价。结果显示:霍邱县最适宜、较适宜、基本适宜、不适宜和最不适宜建设区分别占霍邱县国土面积的14.02%、52.49%、19.64%、2.15%、11.69%;针对适宜性等级,提出科学合理的土地利用对策,为霍邱县土地利用规划等相关工作提供借鉴意义。

Scientific evaluation methods and techniques are the basis for the rational use of limited land resources.Taking Huoqiu County as an example,based on GIS spatial analysis technology and analytic hierarchy process,it establishes the land suitability evaluation index system and comprehensive evaluation model of Huoqiu County,and evaluates the land suitability of Huoqiu County.The results showed that the most suitable,suitable,basically suitable,unsuitable and least suitable construction areas accounted for 14.02%,52.49%,19.64%,2.15%and 11.69%of the land area in Huoqiu County,respectively.According to the level of suitability,scientific and rational land use countermeasures are proposed.It provides reference for relevant work such as land use planning in Huoqiu County.
