| 摘 要： | 研究合肥市区不同功能区景观林组成与结构,共记录102个样方。结果表明:景观林主要组成种有111种,分属45科、81属;主要优势种是香樟、枫杨、水杉、杨树、桂花、石楠等;不同功能区景观林树种相似性系数分别为0.4(公园与居住区)、0.24(高校与居住区)、0.22(公园与高校);林分平均密度560株/hm2,平均基盖度18.83 m2/hm2,平均胸径16.99 cm,平均树高10.13 m,均为正态分布。群落类型可归纳为5个植被型、16个群系及69个群丛,以落叶阔叶型与常绿落叶阔叶混交型为主。建群树种主要有香樟、广玉兰、女贞、雪松、水杉;群落外貌较整齐,树木整体较为健康,景观效果较佳;但层次结构、树种多样性不高,应丰富树种,增加群落的垂直层次,采用近自然经营。

| Abstract: | Based on field survey of 102 samples, the paper studied the species composition and stand structure of ur- ban landscape woodland in different function areas of Hefei City, and community characteristic value were analyzed in this paper. The results revealed that total 111 tree species, 45 famihes and 81 genus were identified in the landscape woods, with the major dominant species were Cinnamomum camphora, Pterocarya stenoptera, Metasequoia glyp- tostroboides, Populus spp, Osmanthus fragrans, Photinia serrulata etc. The similarity index of species identified in landscape woods at different function areas were 0. 4 （parks and resident areas）, 0. 24 （ university campus and resi- dent areas）, and 0. 22 （parks and university campus） . The stand average density was 560 plants/ha, stoking densi- ty 18.83 m2/ha, DBH 16. 99cm, and tree height 10. 13m, and all of these showed a nearly normal distribution. The communities were classified as 5 vegetation types, 16 formations and 69 associations, among which the main types were both deciduous broad - leaved woods and evergreen and deciduous broad - leaved mixed forest, and the major canopy species were Cinnamomum camphor, Magnolia grandiflora, Ligustrum lucidum, Cedrus deodara, Metasequoia glyptostroboides, etc. The whole landscape woods community had a better appearance, healthy trees and higher aes- thetic effect, but with lower species diversity and poor vertical structure. Authors suggested that more tree species should be used to improve the layer structure and close -to -nature management should be taken in the future. |
