| 以贵阳市黔灵山公园为研究对象，选取24个植物景观单元。以生态适宜、景观适宜、社会适宜为准则层，建立山地公园植物景观景观适宜性评价体系。运用主成分分析确定评价指标权重，克服以往植物景观评价赋权重的主观性，建立山地公园植物景观景观适宜性评价模型，得到不同植物景观的景观适宜性指数。结果表明：黔灵山公园在适宜范围内的植物景观有10个，占评价单元总数的41.6%，适宜性较差的有14个，乔灌比(数量)在1:11.2~1.7:1之间的植物群落景观适宜性较好。根据评价结果，提出了3点山地公园植物景观营建策略，以期为山地公园植物景观评价及营建提供理论指导。 |

| Abstract: |
| A total of 24 plant landscape units were selected from Qianling Mountain Park of Guiyang City. Based on ecological suitability, landscape suitability and social suitability, the evaluation system of plant landscape suitability in mountain park was established. It used the principal component analysis (PCA) to determine the weight of evaluation index, to overcome the subjectivity of heavy weight of plant landscape evaluation in the past, to establish the evaluation model of plant landscape suitability in mountain park, and to obtain the landscape suitability index of different plant landscape. The results showed that there were 10 plant landscapes in Qianling Mountain Park, accounting for 41.6% of the total number of evaluation units, 14 of them had poor suitability, and the plant community landscape suitability of tree and shrub ratio (quantity) was 1:11.2-1.7:1. Based on the evaluation results, three strategies for plant landscape construction in mountain parks were put forward in order to provide theoretical guidance for plant landscape evaluation and construction in mountain park. |
