| 摘 要： | 目的 分析浙江省杭州市临安区钱王陵公园植物群落结构，并对其生态效益进行定量评估。 方法 以临安钱王陵公园为研究对象，对公园内32个植物群落资源结构进行实地调查，运用i-Tree模型评估群落节能、吸收二氧化碳(CO2)、改善空气质量、截留雨水等生态效益。 结果 ①所调查群落树木共计1 613株，分属39科62属74种；群落结构以复层型为主，呈现出以针阔混交林为主的景观风貌。②群落年生态效益为208 588.16元·a?1，单株树木平均效益为129.25元·株?1·a?1，其中节约能源、吸收CO2、改善空气质量和截留雨水生态效益分别为48 188.80、98 447.36、4 019.84和57 932.16元·a?1，分别占为23.10%、47.20%、1.93%和27.77%；生态效益总价值最高的是樟树Cinnamomum camphora+广玉兰Magnolia grandiflora-山茶Camellia japonica群落(样地L21)，为12 777.60元·a?1，占6.13%，且该群落在节约能源、吸收CO2、截留雨水3个方面生态效益均为最高；针阔混交型群落生态效益占35.47%，对生态效益价值贡献最大。③落叶阔叶及针叶树种单株平均生态效益较高，落叶阔叶树在节能、吸收CO2、改善空气质量及截留雨水效益方面更具优势。 结论 钱王陵公园植物群落生态效益的高低主要取决于群落内树种的株数、生长类型和平均胸径，针阔混交型群落在生态效益价值方面具有明显优势。图2表4参23

| Abstract: | Objective This research aims to analyze the plant community structure of Qianwangling Park in Lin’an District of Hangzhou City, Zhejiang Province, and evaluate its ecological benefits. Method Taking Qianwangling Park as the research object, the structure of 32 plant communities in the park was investigated, and the i-Tree model was used to evaluate the ecological benefits of community including energy conservation, carbon dioxide absorption, air quality improvement and rainwater interception. Result (1) There were 1 613 trees in the community, belonging to 39 families 62 genera and 74 species. The community structure was mainly of the multi-layer type, dominated by the landscape style of the mixed forest of needles and broads. (2) The annual ecological benefit of the community was 208 588.16 yuan·a?1, and the average benefit per tree was 129.25 yuan·plant?1·a?1, among which the benefits of energy conservation, carbon dioxide absorption, air quality improvement and rainwater interception were 48 188.80, 98 447.36, 4 019.84 and 57 932.16 yuan·a?1, accounting for 23.10%, 47.20%, 1.93% and 27.77% respectively. The highest total value of ecological benefits reached 12 777.60 yuan·a?1, found in sample L21 (Cinnamomum camphora+Magnolia grandiflora-Camellia japonica community), accounting for 6.13%. This community had the highest benefits in saving energy, absorbing carbon dioxide and intercepting rainwater. The mixed community contributed the most to ecological benefit values, accounting for 35.47%. (3) The deciduous broad-leaved and coniferous trees had higher average benefits per plant, and deciduous broad-leaved trees had more advantages in energy conservation, CO2 absorption, air quality improvement and rainwater interception. Conclusion The ecological benefit of plant community in Qianwangling Park is mainly determined by the number of tree species, growth type and average diameter at breast height. The coniferous and broad-leaved mixed community has obvious advantages in ecological benefit value. Ch, 2 fig. 4 tab. 23 ref.] |
