大连城市行道绿化树种的选择及配置原则研究

The Selection and Disposition Rule of Dalian City Shade Trees

在充分调查及分析大连城市中心区的自然地理环境及其各功能区内行道具体小环境的基础上，认为选择与配置行道绿化树种的基本原则：一是因地制宜地在不同功能区内栽培不同树种；二是合理引进驯化外地树种以丰富城市行道景色；三是套种速生树种与慢生树种以满足长远规划的需要；四是生态功能与经济效益相结合，在一定程度上实现以绿化养绿化的可持续性发展．

On the basis of fully investigated and analysed the nature environment of Dalian urban district and the microenvironment of the city functional zones, we suggested that the basic rule to select and dispose shade trees is that we should plant different species in different functional zone in the light of local conditions. Second, we should introduce fine varieties of other places to enrich the city's road scene. Third, we should interplant short life and long life species to meet the needs of the city's long-term plan. Forth, we should integrate ecological function needs with economic benefits needs together, and to a certain extent we will realize continuable development of city road virescence.
