基于GIS的香港泳滩适宜性评价模型.pdf

27地理信息世界GEOMATICS 【摘要】泳滩是滨海旅游业的一个重要部分,本文以香港泳滩为研究对象,对该区域的综合条件进行剖析,根据其影响因素的类型选取了自然条件,社会经济条件,以及泳滩自身条件作为泳滩适宜性评价的主要因素,并对评价指标进行归纳和分类,建立起较为完善的泳滩适宜性评价的指标体系。运用层次分析法,比较评价指标之间重要性关系得到各影响因素对泳滩适宜性的影响权重,通过地理信息系统(GIS)的建模方法对各种因素进行空间分析,最终得到香港泳滩的评价等级结果。该模型的构建理论和方法可以为海岸资源的管理和开发提供参考和技术支撑,有利于泳滩旅游业的可持续发展。【关键词】地理信息系统;泳滩;适宜性评价;空间建模Hong Kong Beaches Suitability Evaluation Model Based on GISAbstract:Beach is an ponent of coastal tourism. This research regards beaches in Hong Kong as objects and chooses natural condition, socioeconomic condition and beach own condition as three main factors of beach suitability evaluation according to the strength of influencing elements. Through the induction and classification of evaluation criteria, a rather systematic criteria structure can be built up. Each criterion weight can be got paring the influencing degree of two by Analytical Hierarchy Process (AHP).Then these factors should be processed through spatial analysis using GIS modeling. The result is a beach suitability grade map of Hong Kong. The theory and methodology established by this model can provide reference and technology skill for coastal resource management and development. In addition, it is also profitable for the sustainable development of beach words: Geographic Information System; Beaches; Suitability Evaluation; Spatial Modeling基于GIS的香港泳滩适宜性评价模型文章编号:1672-1
