济南市木本园林植物资源调查与分析   总被引:3,自引:1,他引:2  
张鹤  周君 《中国农学通报》2015,31(22):148-151
为全面系统地掌握济南市木本园林植物的种类组成、生活型、季相特点以及应用现状,对济南市的木本园林植物进行全面、具体、系统、深入的调查。调查结果显示,济南市木本园林植物共计535种(包括变型、亚种和栽培变种),隶属于77科199属。其中裸子植物5科16属49种,被子植物72科183属486种(含双子叶植物69科174属467种,单子叶植物3科9属19种),济南市木本园林植物树种较为丰富。乔木植物286种,占所有种的53.4%;灌木植物216种,占所有种的40.4%;藤本植物33种,占所有种的6.2%,乔、灌类植物都比较丰富,藤本比较缺乏。所有树种中常绿树种103个,占所有种的19.25%;落叶树种432个,占所有种的80.75%;落叶树种占据优势。济南市的木本植物应用形式较为多样,但创新性应用不多。济南市木本园林植物应用方面存在的问题有:(1)济南园林树种数量较多,但优质利用的却不多;(2)济南市常绿树种应用较少;(3)乡土树种应用不够。建议:(1)科学搭配城市园林绿化树种;(2)推广栽植乡土树种;(3)积极引种驯化。调查结果为济南的木本植物资源可持续利用提供了可靠的科学理论依据。  相似文献

To study the basic situation of application of local landscape plants in Tibet, local landscape plants in Tibet was investigated firstly by using "biological five-point method". The results show that 213species(including breed) of local landscape plants were applied in Tibet, belonging to 148 genera and 66 families. In the arbor layer, shrub layer and herbaceous layer, the importance of Picea likiangensis Pritz.var. likiangensis Cheng et L. K. Fu, Platycladus orientalis Franco cv. Sieboldii, and Poa pratensis L. were the highest, namely 43.050, 19.696 and 45.950. Rosaceae, Salicaceae, Fabaceae, Poaceae, Pinaceae, Asteraceae,and Cupressaceae were applied mostly, including 25, 16, 12, 11, 10, 9 and 8 species of plants, accounting for11.73%, 7.51%, 5.63%, 5.16%, 4.69%, 4.23% and 3.76% of the investigated plants respectively. Based on this, 11 species of good local landscape plants in Tibet were selected to analyze their application potential in gardens. Rational suggestions about the development and utilization of local landscape plants in Tibet were proposed finally.  相似文献

To analyze the basic conditions of constant colored-leaved tree species in Tibet, this study applied the "biological five-point method" to investigate the plant communities layer by layer, investigated landscape plant species and their landscaping application in Tibet. The results showed that(a) there are 40 constant color-leaved species(including varieties) in Tibet, belonging to 35 genera, 22 families, including 26 tree species and 16 shrub species. In terms of color, 22 species are yellow, 9 purple, 7 red and 2 others, occupying 55.00%, 22.50%, 17.50% and 5.00% of the total constant color-leaved species, respectively.(b) In the tree layer, the species ranking the top 2 of the importance value list are Prunus cerasifera Ehrhar f. atropurpurea Rehd. and Photiniax serrulata ‘Rubens' with an importance value of 26.063 and 9.035; in the shrub layer, the species ranking the top 3 of the importance value list are Ligustrum × vicaryi Hort, Berberis thunbergi var. atropurpurea Chenault, Platycladus orientalis cv. Aurea Nana with an importance value of 22.577, 18.987 and 10.529.(c) The most-applied species belong to the Rosaceae(9), Leguminosae(5), and Oleaceae(3), accounting for 22.50%, 12.50% and 7.50% of the total investigated constant color-leaved species, respectively.(d) Most of the investigated species grow well, but some of them including Berberis thunbergii var. atropurpurea Chenault grow moderately, Loropetalum chinense var. rubrum, Aucuba chinensis var. iegata grow poorly, and the causes of poor growth should be explored further or application of these species should be controlled. In addition, pertinent suggestions were put forward in view of major problems in the application of constant color-leaved species in Tibet.  相似文献

低碳城市南昌主干道路植物景观评价研究   总被引:1,自引:1,他引:0  
为了明确低碳城市南昌道路植物景观的现状和影响道路植物景观的重要因子,为南昌及中国其他低碳城市道路植物景观规划与设计提供依据。采用描述因子法,选择若干对道路植物景观效果贡献较大的指标,建立了整体指标评价体系。采用景观综合评价指数法模型,通过评价因子的权值确定和指标的量化,对南昌城市主干道路植物景观进行了分析评价。结果表明,南昌市道路植物景观整体建设水平较好,57.14%的道路植物景观评价结果在Ⅱ级以上,III级占35.71%,但也有7.14%的道路在Ⅳ级以下。在所评价的8个因子中,得分最高的是植物景观与硬质景观的和谐性,其次是植物景观与整体环境的协调性,植物生活型结构得分排第3位,这说明南昌城市在整体建设过程中,比较重视植物与道路和周边硬质景观环境的协调与统一,多数路段“乔-灌-草”搭配较为合理;物种多样性和植物观赏特性得分低。南昌城市道路植物景观仍然存在单位空间绿量较低、植物种类应用欠丰富,以及地域特色不太突出等问题。针对评价结果,提出了南昌城市道路低碳植物景观和地域特色植物景观营建的建议与措施。  相似文献

By using biological five points,expert consultation and fuzzy comprehensive evaluation,the species,phenological ornamental characteristics,and landscape application of colored-leaf trees in Lhasa City were surveyed systematically. The results show that there are 42 species of colored-leaf trees in Lhasa City,belonging to 31 genera and 18 families,of which there are 5,19,and 18 species of spring,autumn,and common colored-leaf trees,accounting for 11.90%,45.24% and 42.86% of total number of the investigated tree species respectively. It is clearly seen that there are too few species of spring colored-leaf trees in the city. There are 19 and 17 species of trees possessing red and yellow leaves,while the leaves of other 6 species of colored-leaf trees are shown in other colors,and the number of their species accounts for 45.24%,40.48% and 14.28% of total number of the investigated tree species respectively. The best ornamental periods of spring,autumn and common colored-leaf trees in Lhasa City average 38.4,41.8 and 251.8 d respectively. Prunus cerasifera Ehrhar f. atropurpurea Rehd.,Ulmus pumila L.,Populus × beijingensis W. Y. Hsu,and Salix alba are applied most frequently in Lhasa City,and their relative frequency is 18.67%,10.29%,9.91% and 8.95% respectively. According to the comprehensive assessment value of their ornamental characteristics,the ornamental characteristics of 15 species of colored-leaf trees in Lhasa City are good or very good,and there is a positive correlation between the comprehensive assessment value and relative frequency. Based on the investigation,the current application situation and problems of colored-leaf trees in Lhasa City were analyzed,and solutions to the problems were proposed.  相似文献

Landscape change and its driving forces are always one of the major issues in landscape ecology. In this paper,we investigated the landscape pattern of Nanling National Nature Reserve using TM data and forest stand map. The paper aims at exploring how and why the landscape changed form 1988 to 2009. The results indicated that: the major landscape types are evergreen broad-leaved forest and coniferous forests,the area ratio of both total more than 80%; area ratio of other landscape types is less than 10%,including mainly mixed coniferous and broad-leaved forest,deciduous forest,shrub,other woodland,cultivated land,other land,construction land and water. During the 20 years,evergreen broad-leaved forest landscape has become a large-scale substrate,coniferous forests are interspersed,a small area of mixed coniferous and broad-leaved mixed forest patches expands; forest area in the study area changes slightly,the number of blocks increases,the degree of landscape fragmentation increases; forest landscapes change,and are less affected by human activities,which is closely related to the establishment,management and protection of protected areas.  相似文献
