摘 要徐州市市区的野生地被植物种质资源丰富,然而缺乏合理的开发与利用。本文采用实地抽样调查与全面普查相结合的方式,点面结合、以点带面的原则调查了徐州市市区野生地被植物的种类、分布情况、生态习性以及园林应用现状,总结出徐州市市区常见的野生地被植物共119种,隶属45科,104属,其中多为草本类观花、观叶植物。本文采用多属性综合评价体系的线性加权综合法对119种野生地被植物进行定量计算评估,并提出蛇莓、婆婆纳、二月兰等25种野生地被植物具有一定的开发前景,建议在本地园林中加以利用。对野生地被植物在园林中的应用现状进行了初步探讨,提出增加野生地被植物的应用种类和数量、对野生地被植物进行合理配置、加强野生地被植物的筛选与培育、建立专门的生产基地的建议。72930

Investigation of Wild Ground Cover Plants in Urban Areas of Xuzhou City
Abstract Germplasm resources of the wild cover plants of urban areas in Xuzhou City are abundant。 However, the city failed to develop and utilize these resources rationally all the time。 By using the methods of sample survey and generalcensus, following the principles of integrate point and sphere and point to area, this article investigates the types, distributed situation, ecological habits and the landscape application’present situation of the wild cover plants in Xuzhou City。 In addition, this article sums to 119 common kinds of wild cover plants which attach to 45 families and 104 genus, most of them are herbal flower ornamentals or foliage plants。 This article also estimates these wild cover plants quantitatively by the linear weighting method of multi-attribute comprehensive evaluation system。 As a result, Duchesnea indica, Veronica didyma, Orychophragmus violaceus and other 25 kinds of wild cover plants which have promising prospect are selceted to be expoited in local landscape。 Finally, this article also makes a preliminary exploration on the application of wild cover plants for landscape and gives the advices to increase the species number of the wild cover plants, allocate the wild cover plants rationally, strengthen the selection and breed of the wild cover plants as well as found the special production bases。

1 绪论
野生地被植物指的是具有某种观赏价值,但至今仍处于自然或半自然生长状态,还没有被完全开发利用、人工栽培驯化的地被植物[1]。近年来,随着环境污染的加重,水土的流失,人们逐渐认识到地面绿色植被的重要性,开始加大地被植物的覆盖面积以保持水土、改善环境。随着城市生态园林的日益发展,作为本地自然生态系统重要组成部分的野生地被植物,具有极强的适应能力,较高的观赏价值与生态安全性,易于养护管理,种植维护成本较低,本土气息浓厚,有利于改善当地环境,体现地域性植被特色,因此被越来越多地应用于园林当中。
