徐州城市森林发展研究

分析了植物分布理论、生态演替理论、生物多样性理论、景观结构理论等城市森林建设的基础理论;基于野外调查资料建立了徐州低山丘陵森林植被分类系统,包括2个植被型组、3个植被型、3个植被亚型、6个群系组、12个群系(赤松林、黑松林、侧柏林、刺槐林、黄连木 黄檀林、青檀林、小叶朴林、鹅耳枥林、麻栎林、栓皮栎林、白栎林、栓皮栎 红楠林);根据建群种与光照强度的关系研究了各群系的演替次序,构建了徐州低山丘陵森林植被次生演替模式.在上述研究的基础上论述了徐州城市低山丘陵森林、城市行道树林以及城市园林的发展.

Research on Urban Forest Development in Xuzhou

Such theories as plant distribution theory,ecological succession theory,biodiversity theory and landscape structure theory on which urban forest building is based are discussed.Based upon the field survey material,the classification system of the forest vegetation on hills in Xuzhou is established,including 2 vegetation type groups,3 vegetation types,3 vegetation subtypes,6 formation groups and 12 formations(i.e.,Pinus densiflora forest,Pinus thunbergii forest,Platycladus orientalis forest,Robinia pseudoacacia forest,Pistacia chinensis Dalbergia hupeana forest,Pteroceltis tatarinowii forest,Celtis bungeana forest,Carpinus turczaninowii forest,Quercus acutissima forest,Quercus variabilis forest,Quercus fabri forest and Quercus variabilis Machilus thunbergii forest).According to the effects of light intensity on forest edificators,the successional relationships among the 12 formations are analyzed,and the secondary succession model of the forest vegetation on hills in Xuzhou is built.Guided by the above results,the development strategies about urban hill forest,urban street forest and urban garden/park in Xuzhou are put forward.
