镜泊湖风景名胜区旅游用地开发适宜性分区研究

Regionalization of Feasible Development of Tourism Land Use in Historic and Scenic Spot of Jingpo Lake

针对镜泊湖风景名胜区旅游用地开发与保护的矛盾,利用调查资料和现有研究成果,从限制约束与优势引导两个方面建立旅游用地开发适宜性分区评价因子体系,在GIS技术支持下,将研究区划分为1 896个1km×1km网格评价单元,利用GIS缓冲区处理、网格分析、叠加、链接、数据统计等功能,将不同的评价因子切分到的各个网格单元中,采用层次分析法确定评价因子权重,然后分别计算出每个网格单元的开发适宜性指数,最后采用GIS聚类分析功能得到镜泊湖风景名胜区旅游用地开发适宜性分区图及各区面积。结果表明:镜泊湖风景名胜区旅游用地可以划分为优先开发区、适度开发区、限制开发区、适度保护区、优先保护区,分别占总面积的3.55%,25.59%,23.57%,37.83%,9.46%。不同分区的发展方向和管制要求为镜泊湖风景名胜区旅游用地合理有序开发和保护提供科学的依据。

According to contradictions on development and protection of scenic spot for tourism of Jingpo lake,suitability partition evaluation factors system of development for tourism was established by using survey data and the existing research results from two aspects of restriction and advantage.The researched area is divided into 1 896 grid units under technical support of GIS.The different evaluation factors are segmented to each grid unit by using function of its dump buffer processing,grid analysis,stack,links and data statistics etc.different evaluation factors segmentation to each grid unit.Evaluation factor weights are confirmed by adopting hierarchical analysis.We can calculate each grid unit development suitability index separately by using the GIS spatial analysis function,and then to use GIS cluster analysis function to get development suitability partition map and district area for tourism of Jingpo Lake scenic spot.The research result show that historic and scenic spot can be divided into priority development area,moderate development zone,restrict development,moderate reserve and priority reserve,the proportion were 3.55%,25.59%,23.57%,37.83%,9.46%,respectively.The development direction of different partitions and request of management system provide scientific basis for reasonable and orderly development and protection of Jingpo Lake.
