摘要
为营建生态与美学协同高效的公园植物群落,提升城市公园绿地质量,以保定市竞秀公园为研究对象,采用i-Tree模型及美景度评价法分别评价植物群落的生态及美学效益。基于耦合协调模型衡量二者间的协调程度,并结合群落特征指标进行相关性分析。结果表明:(1)植物群落生态效益与平均高度和群落密度之间呈极显著正相关,与平均冠幅、平均胸径及郁闭度具有显著正相关关系。(2)植物群落美景度与平均胸径、乔木占比、色彩丰富度呈显著正相关,与群落密度、郁闭度呈显著负相关。(3)耦合协调度与平均高度、平均冠幅、平均胸径呈极显著正相关,与乔木占比之间呈显著正相关。(4)平均胸径、平均高度、平均冠幅、乔木占比和色彩丰富度为促进因子,群落密度与郁闭度为权衡因子;当郁闭度为80%,群落密度为0.108株/m^(2)时,生态与美学效益达到相对平衡。根据影响因素并结合现状,提出植物群落优化策略,提升城市公园植物群落质量,营造出生态与美观兼具的公园环境。
In order to build an ecological and aesthetic synergistic as well as efficient plant communities in parks,improve the quality of urban park green space,with Jingxiu Park in Baoding as the research object,i-Tree model and scenic beauty evaluation method were used to evaluate the ecological and aesthetic benefits of plant communities.The degree of coordination between the two groups was measured based on the coupling coordination model,and the correlation analysis was carried out based on the community characteristic index.The results showed that:(1)The ecological benefit of plant community was extremely significant positively correlated with average height and community density,and was positively correlated with average crown width,average DBH and canopy density.(2)The beauty degree of plant community was positively correlated with mean DBH,tree proportion and color richness,and negatively correlated with community density and canopy density.(3)The coupling coordination degree was extremely significant positively correlated with average height,average crown width and average DBH,and was positively correlated with tree proportion.(4)Mean DBH,mean height,mean crown width,tree proportion and color richness were the promoting factors,while community density and canopy density were the tradeoff factors.When the canopy density was 80%and the community density was 0.108 plants/m^(2),the ecological and aesthetic benefits reached a relative balance.According to the influencing factors and the current situation,the optimization strategy of plant community was put forward to improve the quality of plant community in urban parks and create a park environment with both ecology and aesthetics.
