【摘要】 本文在全面调查、统计和分析南宁市花卉公园园林植物物种资源的基础上,根据植物景观的分类选取53个典型植物群落样地,运用SBE法和AHP法评价其景观质量,主要研究结果如下:1.南宁市花卉公园共有园林植物302种,隶属84科220属。其中有乔木和竹类137种,灌木74种,草本85种,藤本6种,分别占总种数的45.36%、24.50%、28.15%和1.99%;木本植物中有常绿树种167种(占79.15%),落叶树种44种(占20.85%),常绿树种与落叶树种比例约为4:1;含多种的科有豆科、禾本科、棕榈科、桑科、龙舌兰科、大戟科等6科,寡种科和单种科植物种类虽少,但种植应用的面积较大;乡土植物164种,外来植物138种,分别占总种数的54.30%和45.70%;观花植物140种,观叶植物151种,观果植物34种,观干植物35种,分别占46.35%、50.00%、11.23%及11.59%。总体而言,公园园林植物物种多样性丰富,但应用彩叶植物、观果植物、观干植物种类较少。调查分析结果还表明,该公园花文化具有闲适性、多功能性及科普性,具有一定文化内涵的植物达177种,隶属于68科146属。2.通过运用SBE法评价植物群落景观结果表明,YSBE均值最大为0.662,最小值为-0.937,其中YSBE为正值的有24个样地,其余样地呈负值,说明所调查植物群落中,优良率较低;通过运用AHP法评价植物群落景观样地结果显示,YAHP最大均值为9.396,最小均值是3.734,YAHP均值主要在5～8之间,植物群落景观得分水平偏上,表明花卉公园植物景观质量整体较好;所选取的53个植物群落样地以CEI作为分级依据,得出I、II、III、IV、V级植物群落景观分别有5个、14个、13个、15个和6个,分别占评价群落总数的9.43%、26.42%、24.53%、28.30%及11.32%。由此可知,花卉公园植物群落景观总体处于中等偏上的水平,但评价值较高的I级景观的植物群落数量相对较少,表明花卉公园景观的优质植物群落较少。3.SBE法和AHP法对所选取的植物群落景观评价排序差值在0～20之间的有42个,占植物群落总数的79.25%,虽然评价结果不完全一样,但两种评价方法的评价结果呈现较高的一致性。通过对两种评价方法评价结果进行回归分析,可得影响评判者评分的主要因子有植物群落的乔木层特征(C10)、植物观赏特性(C1)、植物景观空间(C7)、植物景观特色(C15)、植物景观的色相和季节变化(C3),说明评判者主要注重植物景观的美学功能。本文通过两种评价方法对南宁市花卉公园植物群落进行景观评价,结果表明其植物群落景观处于中等偏上水平,但景观优质的植物群落相对较少。4.调查和分析结果表明,南宁市花卉公园植物景观特色鲜明,但也存在如下问题:植物重复应用多,景观相似度高;藤本植物应用少,垂直绿化景观缺乏;植物文化底蕴不足,挖掘力度尚浅;绿地养护管理不到位,植物景观人为破现象时有发生。针对问题,文章提出了以下初步建议:丰富植物多样性,营造四季分明的景观效果;加强藤本植物运用,营造竖向空间美感;挖掘花卉文化内涵,加强科普教育功能;加大植物养护管理力度,制定护理措施。更多还原

【Abstract】 Based on the comprehensive investigation,statistics and analysis of the garden plant species resources of Nanning Flowers Park,53 typical plant community plots were selected according to the classification of plant landscapes,and the landscape quality was evaluated by SBE method and AHP method.The main research results are as follows:1.There are 302 kinds of garden plants in Nanning Flowers Park,belonging to 84 families and 220 genera.Among them,there are 137 species of trees and bamboos,74 species of shrubs,85 species of herbaceous plants and 6 species of vines,accounting for 45.36%,24.50%,28.15%and 1.99%of the total species,respectively.There are 167 species of evergreen trees(79.15%),and 44 species of deciduous trees(20.85%)in woody plants,the ratio of which is about 4:1.The families with multiple seeds include leguminous,gramineous,palm,mulberry,agave and euphorbiaceae.Although the number of species with few or single seed is limited,the planting area of these plants is large.There are 164 species of native plants and 138 species of exotic plants,accounting for 54.30%and 45.70%of the total species,respectively.There are 140 species of flowering plants,151 species of foliage plants,34 species of fruit plants,and 35 species of dried plants,accounting for 46.35%,50.00%,11.23%and 11.59%,respectively.In general,the garden plants in the park are rich in species diversity.However,there are few types of colored leaf plants,fruit-seeding plants,and dried plants.The results of the survey also showed that the park’s flower culture has leisure,versatility and science,and there are 178 species of plants with certain cultural connotations,belonging to 68 families and 146 genera.2.The results of plant community landscape evaluation by SBE method show that the maximum of average value of YSBE is 0.662 and the minimum value is-0.937.There are 24 plots with positive YSBE,and the other plots are negative,indicating that the excellent rate of the plant community investigated is low.The results by AHP method show that the maximum mean value of YAHP is 9.396,and the minimum value is 3.734,mainly between 5 and 8.The score of plant community landscape is higher,indicating the quality of the plant landscape in the park is generally good.The 53 plant community plots selected are classified by using CEI,and the number of class Ⅰ,Ⅱ,Ⅲ,Ⅳ,and V plant community landscapes account for 9.43%,26.42%,24.53%,28.30%and 11.32%of the total number of evaluation communities,respectively.It can be seen that the plant community landscape of the flower park is generally at the upper-middle level,but the number of plant communities in the I-level landscape with higher evaluation value is relatively small,indicating that there are fewer high-quality plant communities in the flower park3.The SBE method and the AHP method have 42 rankings between 0 and 20,which account for 79.25%of the total number of plant communities.Although the evaluation results are not identical,the evaluation results of the two evaluation methods show a high degree of consistency.Regression analysis was performed on the evaluation results of the two evaluation methods,the main factors that influence the score of the judges are the arbor layer characteristics(C10),plant ornamental characteristics(C1),plant landscape space(C7),plant landscape characteristics(C15),plant landscape hue and seasonal changes of plant communities(C3),explain that the judges mainly focus on the aesthetic function of the plant landscape.In this paper,the landscape evaluation of plant communities in Nanning Flowers Park is carried out by two evaluation methods.The results show that the plant community landscape is above the upper-middle level,but the number of plant communities with high quality is relatively small.4.The results of investigation and analysis show that the plant landscape of Nanning Flowers Park has distinctive features,but there are also some problems such as repeated plant application,high landscape similarity,less application of vines,lack of vertical greening landscape,and insufficient plant culture and excavation.The management of green space conservation is not in place,and the phenomenon of artificial destruction of plant landscapes has been going on as well.In response to these problems,the paper puts forward the following preliminary suggestions:enrich plant diversity,and create a landscape effect with four distinct seasons;strengthen the use of vines to create a vertical space aesthetic;excavate the cultural connotation of flowers,and strengthen the function of science education;strengthen the management of plant conservation,and develop practical care measures.更多还原
