【摘要】 由于地质灾害对人类的生命和财产造成了严重的危害,决定了城市土地开发与利用的复杂性。因此,从防灾角度评价城市建设用地适宜度,对于一个城市用地开展防灾减灾工作十分必要的,也是对一个城市可持续发展至关重要。在GIS技术平台上构建评价模型,将多准则评价方法应用于建设用地适宜度评价的防灾决策中,有助于提高决策分析的科学有效性,提高城市的防灾减灾能力。提出了应用于防灾决策的多准则评价方法,介绍了层次分析法(AHP)、研究了有序权重平均法(OWA)多准则评价方法和多目标决策分析。以唐山市建筑用地防灾适宜度评价为例,通过对相关资料进行综合全面的分析,筛选出对研究对象起主导(或限制)作用的影响因子。采用BI和OWA多准则评价方法,从防灾的角度建立了唐山市不同目标建设用地适宜度评价模型。依据模型计算结果,介绍了居民用地和工业用地开发选址的几种方法,分析了多目标冲突区域。通过选取各个目标的适宜度阈值,利用目标之间的权重调节优先度实现多目标区域合并。分析了唐山市防灾建设用地的合理性并得出今后应加大西北部住宅区用地和周边地区工业建设用地的结论,为更好地利用有限的土地资源提拱了科学依据。更多还原

【Abstract】 Geological disasters seriously harm people`s lives and property, the city`s land development and utilization is complex. Therefore, the evaluation of construction land based on disaster prevention is necessary both for the city`s disaster prevention work and sustainable development.Evaluation model is established on GIS. Multi-criteria evaluation method is applied to decision-making of suitability evaluation of construction land for disaster prevention in city, which is good at scientifically managing and improving the ability of disaster prevention and reduction engineering in city. Multi-criteria evaluation based on GIS is produced, such as AHP, the implementing method of OWA multi-criteria evaluation methods and Multi-Objective Decision Making in GIS.Construction land suitablity evaluation of Tangshan for disaster prevention is taken as an example. The factors dominating or constraining are screened out according to the analysis of the related data all over. BI and OWA are used for the different targets of construction land suitability evaluation of Tangshan for disaster prevention. Following the result of the modle, several ways of selecting the appropriate address for residential land and industrial land are introduced and the conflicting areas of multi-objectives are analyzed. According to selected suitability threshold of each objective, the fixed weight of each objectives regulate priority for merge multi-objective. The rationality of construction land for disaster prevention in Tangshan is analyzed and it is concluded that the north-west area for residential land and the surrounding area for industrial land should be increase in the future, so the scientific basis can be supplied for better utilization of limited land resources.更多还原
