基于生态适宜性分析框架的丽水植物园生态景观林空间规划研究

Spatial Planning of Ecological Landscape Forest of Lishui Botanical Garden based on a Ecological Suitability Analysis Framework

摘要:

传统景观林规划方法已不能满足大众对生态景观林功能多元化的要求。基于丽水植物园山地环境的多项参数，采用 GIS 空间分析、聚类分析等方法对场地生态适宜性，即生态敏感性和生境质量进行分类评价，根据分析结果进行生态景观林空间初步规划。结果显示：丽水植物园按照生态风险等级可分为 5 类敏感性区域，按生境差异则划分为 7 种生境类型。结合生态适宜性分析结果，对基于突出植物保护、公众教育及森林康养 3 个不同的功能指向性规划目标，按照不同的要求进行空间叠加、重分类和整理，分别进行生态景观林空间规划，并针对性推荐部分造林树种。

Abstract:

The traditional planning method of landscape forest cannot atisfy the public’s requirement for diverse ecological functions. Based on the quantitive environmental parameters of Lishui Botanical Garden, GIS spatial analysis, cluster analysis and other methods were used to classify and evaluate the ecological suitability analysis, involving ecological sensitivity and habitat quality of the site, which were applied to guide the spatial planning of ecological landscape forest. The results showed that according to the ecological risk level, Lishui Botanical Garden was divided into five types of sensitive areas, and according to the habitat differences, it was divided into seven types. Combined with the results of ecological suitability analysis and spatial superposition according to different requirements, the spatial planning and afforestation tree species selection of ecological landscape forest can be carried out respectively based on three different functional scenarios of highlighting plant protection, public education and forest health rehabilitation and recreation.
