Evaluation of Landscape Resources of Urban Forest Park Based on GIS – Take Beijing Tongzhou Grand Canal Forest Park as an Example

摘要

Urban forest parks are different from urban parks and forest parks. They are located in the central area or suburbs of the city. They are supported by forest ecological landscapes, supplemented by man-made natural landscapes, and provide the citizens with a place for forest ecotourism, which has certain special characteristics. Therefore, the evaluation of landscape resources of urban forest parks can objectively analyze the landscape effects of urban forest parks. This paper takes Beijing Tongzhou Grand Canal Forest Park as an example. Based on the basic geographic data combined with DEM as the data foundation, the ENVI software and Arc GIS software are used as the specific implementation platform to select the representative forest park 18 scenes. Quantitative analysis of slope, aspect, elevation, and landscape visual sensitivity. Finally, it was found that the scenic spots of scenic spot 2, scenic spot 4 and scenic spot 15 were lower; the scenic spots 1, scenic spots 6, and scenic spots 14 and 18 scored higher. This verifies the feasibility of applying GIS technology in landscape resource evaluation of urban forest parks, and provides reference and basis for landscape resource evaluation techniques in similar areas.
