基于综合景观指数的城乡结合部边界划分

Urban-rural Fringe Division Based on the Landscape Pattern Index

总结单一景观指数模型提取城乡结合部边界存在的问题，提出综合景观指数模型。同时指出，唯有将城市扩展方向信息与指数模型相结合，才能提高城乡结合部的提取精度。以成都市为例，应用遥感和GIS技术，根据建立的模型，计算出各判别单元的综合景观指数，并将综合景观指数在0～22之间的判别单元划分为城乡结合部。

In this paper,we firstly summed up the single landscape index model to extract urban-rural fringe and proposed a comprehensive landscape index model.At the same time,it pointed out that only if we combine the direction information of urban expansion and the index model can we improve the extraction accuracy of the urban fringe and a case study of Chengdu.Combination with the methods of RS and GIS,calculating the comprehensive landscape index of each cell based on the established model,the cell that comprehensive landscape index values between 0to 22 is divided into urban-rural fringe.
