摘要:

市树是城市形象的重要标志和文化名片,科学选用市树对于优化城市人文生态环境、促进地方文化的传承和发展能起到积极的推动作用。本文利用国家林业局2017年全国市树调查统计数据,对我国34个省级行政区域的348个地级以上城市的市树选用情况进行统计分析和归纳汇总,探讨市树的选择程序与确定原则,分析我国市树选择应用整体状况、区域分布特征和市树应用中的有关问题,以期为我国城市市树选择应用与绿化工作提供参考。分析结果表明:我国目前共有245个城市已确定市树,占全部城市总数的70.4%,并有27个城市同时选用两个树种作为市树,其中,北京、天津和重庆三个直辖市及河北、江苏、浙江和江西4个省份的全部地级城市已完成市树的选定工作;从树种组成来看,市树种类涵盖29科56属的81个树种,主要集中在松科、豆科、蔷薇科、木犀科、柏科、樟科等,其中国槐、香樟和银杏是选用率最高的三大市树树种,分别被49、49和19个城市选做市树,占已选定市树城市总数的20.0%、20.0%和7.8%,同时,榕树、黄葛树和小叶榕等也是南方城市常用的市树种类;从地理区位的比较来看,我国北方地区城市选用国槐、雪松、油松、榆、垂柳和白蜡等树种作为市树较多,长江流域沿线城市市树选用香樟、油樟、栾树、玉兰等树种较多,东南沿海地区城市选择香樟、凤凰木、扁桃树、桂花等树种作为市树的城市较多;我国不同区域城市的市树选择各具特色,华北、西北地区国槐选用率最高,分别占该区域内已选定市树城市总数的53.3%和50.0%,华中、华东地区香樟选用率最高,分别占该区域内已选定市树城市总数的46.2%和20.3%,而港澳台地区则与华南地区城市在市树选择上有一定的相似性,其重合度达50%。同时,市树选用过程中还存在应用不广泛、运用不合理、名称不规范等诸多问题,科学规范地选用市树仍是我国城市绿化建设过程需要进一步加强的发展方向。

Abstract:

Objective: The scientific selection of city trees is still an important work in the future.Based on the statistical data of the Municipal Tree Survey of the State Forestry Administration in 2017 and related data, the selection of city-trees in 348 cities above prefecture level in China was summarized, and the characteristics of overall application, species selection and regional distribution, application problems of city-trees were analyzed.In order to provide a basis for tree species selection and greening work in cities in China.The analysis results are as follows, there are 245 selected city-trees in China, accounting for 70.4% of the total number of cities, and 27 cities choose two type of city-trees at the same time; all prefecture-level cities in Hebei, Jiangsu, Zhejiang, Jiangxi, and other provinces, as well as Beijing, Tianjin, and Chongqing, have selected city-trees; from the tree species composition, the city-trees cover 81 species of 29 families and 56 genera, mainly concentrated in Pinaceae. Leguminosae, Rosaceae, Oleaceae, Cypress, and Lauraceae plants, among which Sophora japonica, Cinnamomum camphora, and Ginkgo biloba were selected by 49, 49, and 19 cities, respectively. Ficus is the most commonly used urban tree species in southern cities. From the geographical location, the choice of urban trees in different regions has its own characteristics, while in northern cities, S. japonica, cedrus and ginkgo are selected as the most popular ones. Pinus tabulaeformis, elm and weeping willow are more used as city-trees, C. camphora, C.longepaniculatum, Koelreuteria paniculata and magnolia are more used in the Yangtze River valley, camphor, phoenix wood, almond and osmanthus are more used in the southeastern coastal areas, among which the frequency of using S. japonica as city-tree in North China and Northwest China was 53.3% and 50.0% respectively, and the frequency of using camphor tree in central and Eastern China were 46.2% and 20.3% respectively. In the process of choosing city trees, there are still some problems in many cities, such as the application of city trees is not extensive, the use is unreasonable, and the name is not standardized. It is urgent to improve the greening in cities.
