新冠康复期视角下城市森林公园景观评价体系构建研究

Study on the Construction of Urban Forest Park Landscape Evaluation System from the Perspective of COVID-19 Recovery Period

随着我国逐渐步入新型冠状病毒(简称新冠)感染康复期,当前的城市森林公园既要能够满足居民森林游览的日常基础观赏需求,还需兼具防疫性和保健性。因而,在此背景下构建科学合理的森林公园评价体系有着重要的现实意义。文章基于灰色统计法和层次分析法对后疫情时期森林公园景观评价指标进行筛选和权重计算。结果表明:1)经过灰色筛选,共计17项指标通过,4项指标由于与景观评价关联度较弱或指标可测性低等原因未入选;2)准则层的权重排序为景观性B1(0.5584)>防疫性B2(0.3196)>保健性B3(0.1220);3)指标层中的各指标权重排序在首尾的分别是:B1的自然景观色彩多样性(0.3168)、景观构筑物美观性(0.0233);B2的场地通风性(0.4106)、园区出入口有序性(0.0605);B3的杀菌保健型植物种植密度(0.5538)、芳香疗愈型植物种植密度(0.0727)。该研究为构建新型的城市森林公园景观研究提供了参考依据。

As China is gradually entering the period of recovery from COVID-19,current urban forest park should not only meet the daily ornamental needs of residents on forest tour,but also be antiepidemic and health care.Therefore,it is of great practical significance to construct a scientific and reasonable forest park evaluation system under the current background.In this paper,GST method and AHP method were used to screen and calculate the weight of forest park landscape evaluation indexes in the post-epidemic period.The results showed that:1)After grey screening,a total of 17 indicators passed,4 indicators were not included because of weak correlation with landscape evaluation or low testability;2)The weight order of the criterion layer was landscapeB1(0.5584)>epidemic prevention B2(0.3196)>health care B3(0.122);3)In the index layer,the weight order of each index at the beginning and end is:B1 the color diversity of natural landscape(0.3168),the beauty of landscape structures(0.0233);B2 site ventilation(0.4106),park entrance and exit order(0.0605);B3 the planting density of bactericidal health care plants(0.5538)and aromatic healing plants(0.0727).This study provides a reference for constructing a new type of urban forest park landscape.
