摘要
东营市是黄河三角洲的新兴城市,该地区多为滨海盐碱地,因其特殊的立地条件,绿化多以客土为主,随着胜利油田的开发,加快了东营市的建设步伐,树木引种的数量及种类显著提高,但某些树种表现出对盐碱地的不适应,种植搭配不够合理等。经过实地调查,东营市现有园林树种99种,其中常绿树种18种,占18．2%;落叶树种81种,占81．8%;藤本9种,占9%;竹2种,占2%;乔灌比1:1．26;常绿落叶比1:4．5,在此基础上,对东营市树种规划提出建议。
Dongying is a burgeoning city at the Yellow River Delta. The soil in most area here is saline. Hence, people have to transport soil from other places for planting. Following the exploitation of Shengli Oil Field, the development of Dongying is accelerated. The quantity and varieties of introduced trees were increased obviously. But there are some problems, such as some kinds of trees cannot acclimatize the saline - soil; the planting arrangements of different trees are not rational and etc. By surveying on the spot, there are 99 species of trees in Dongying. 81 of them are hardwood trees; 18 of them are evergreen trees; 9 are liana trees; and the last two are bamboo. The ratio of tree to brush is 1/1.26; and of evergreen tree to hardwood tree is 1/4.5. Based on the investigation, some suggestions are put forward.
