摘要本文采用了抽样调查和全面普查相结合的研究方法,对徐州城区内不同类型的园林绿地内的园林树木的生长状况及种类进行调查,结果表明:徐州城区现有园林树木种类共计73科165属233种(部分变种、变型,不含草本、竹类)。乔木、灌木和藤木的种数比例为12:7:1。常绿与落叶的比例为1:2。1。乡土与外来树种的比例为1:1。24,乡土树种较少。其中乔木139种,占全部树种的59。7%,常绿乔木与落叶乔木种数比为1:2。8。灌木82种,占全部树种的35。2%,常绿灌木与落叶灌木种数比为1:1。4。藤本植物12种,占全部树种的5。2%,常绿藤木与落叶藤木之比为1:1。4。针对徐州市园林树木的现状提出以下建议:加大对乡土树种的开发利用,实现节约型的园林绿化;增加徐州城区藤本植物的应用,提高垂直绿化面积;注重树木的养护管理,提高园林景观效果。72079

Investigation and analysis of landscape tree species in Xuzhou City
Abstract This study is research of the garden plant spiece and their groth condition in the xuzhou city of different types of gardens,which has been adopted a comprenhensive survey with sampling survey。The results showed that the Xuzhou City existing landscape tree species in a total of 73 families 165 genera 233 (some variants, variant, does not contain herbs, bamboo)。 Trees, shrubs and vine species ratio is 12:7:1。 The proportion of evergreen tree and deciduous tree species was 1:2。1。 The proportion of native tree species and exotic tree species was 1:1。24, which was less than that of native tree species。 Of which 139 kinds of trees, the total 59。7% species, evergreen trees and deciduous tree species ratio is 1:2。8。 82 species of shrubs, 35。2% species in total, evergreen shrubs and deciduous shrub species ratio is 1:1。4。 Fujimoto of 12 kinds of plants, accounting for 5。2% of all species, evergreen and deciduous vine rattan is 1:1。4。 For the status quo of garden trees in Xuzhou City and put forward the following suggestions: increase of native tree species exploitation, and realizing the economical landscape; increased use of city of lianas and improve three-dimensional green area; pay attention to the maintenance and management of trees, improve the landscape effect。

1绪论
随着经济的发展以及城市化的不断推进,经济发展与环境之间的的矛盾日益凸显,同时人对环境的要求越来越高。在协调经济发展与环境污染的矛盾中,城市绿化起着关键的作用。而园林树木作为城市绿化的不可或缺的组成部分,其种类、数量以及生长发育状况直接影响城市绿化水平。树木作为一种活的有机体,能够改善局部小气候,其花、叶、果姿等能在一年四季中展现出别样的风景,同时其生长也受到地域的限制,因此以地方环境为背景研究当地树木的种类及生长状况以追求更大的生态效益十分重要。
