基于适宜性评价的深圳梅林云步道选线研究

Route Selection of Meilin Trans-urban Connector in Shenzhen Based on Suitability Evaluation

以深圳梅林山云步道为例,探索高密度城市中心区的浅山山地风景游步道的选线研究及建设策略。采用层次分析和开发适宜性评价方法,从空间、生态、行为3个层面,选取了地形地貌、植被、用地阻隔、交通、建设5个因子,建立综合评价体系,生成了梅林山云步道开发适宜性的分级图,结合梅林片区的用地规划、相关保护规划、城市空间格局与以及景观人文资源等现状,将云步道线路与区域、市域绿道系统和周边绿地等对接,在高密度的城市结构中创造展示自然生态法则的山地风景道系统与城市眺望系统。

This paper takes Meilin trans-urban connector in Shenzhen as an example,explores the route selection and construction strategy of shallow mountain scenic hiking trails in high-density city center.Using analytic hierarchy process and development suitability evaluation methods,the paper selects five factors including terrain,vegetation,land barrier,transportation,and construction from three levels of spatial,ecological,and behavioral,to establish a comprehensive evaluation system and obtain a grading map for development suitability of Meilin trans-urban connector.Combining the land use planning,related protection planning,urban spatial pattern,and landscape cultural resources of the Meilin area,the connector is connected with the urban greenway system and surrounding green spaces,to create a mountain scenic path system and a urban observation system that showcases natural ecological principles in a high-density urban structure.
