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.
