基于多重目标适宜性评价的绿道网络选线规划研究--以溧阳市为例

Research on Greenway Network Route Planning Based on Multi-objective Suitability Evaluation--Taking Liyang as an example

绿道已经由初期的游憩路径发展为多功能网络,因此从多目标出发开展适宜性评价对绿道网络选线以及谋划绿道场景营造路径有着重要意义。以溧阳市为例,探索了多重目标下绿道选线的规划方法,在生态保护和景观游憩适应性评价的基础上,加权叠加得到多目标下的综合适宜性评估结果,并结合全域优势资源点位空间分布,构建形成市级、区级两级绿道网络体系。其中,市级绿道主要依托森林廊道、溧阳琴廊及1号公路形成,串联市级以上资源,区级绿道主要依托主干道路及河流,串联区级以上优势资源,从五大方面提出了以绿道为载体进行场景营造的规划路径。研究方法和结果对其他城市绿道网络规划有一定借鉴意义,对提升人民生活质量和城市空间品质有一定价值。

Greenway has developed from the initial recreational path to a multi-functional network. Therefore, it is of great significance to evaluate the suitability of greenway network from the perspective of multiple objectives for route selection of greenway network and planning of greenway scene construction path. Taking Liyang City as an example, the planning method of Greenway route selection under multiple objectives is explored. Based on ecological protection and landscape recreation adaptability evaluation, the comprehensive suitability evaluation results under multiple objectives are obtained by weighted superposition. Combined with the spatial distribution of advantageous resource points in the whole region, the greenway network system at the municipal and district levels is constructed. Among them, the municipal greenway is mainly formed by relying on the forest corridor, Liyang qinlang and No. 1 highway, connecting the resources above the municipal level. The district greenway mainly relies on the main roads and rivers, connecting the advantageous resources above the district level. The planning path of scene construction with greenway as the carrier is put forward from five aspects. The research methods and results have certain reference significance for other urban greenway network planning, and have certain value for improving people’s living quality and urban space quality.
