| 摘 要： | 本文研究了北京市首钢工业区和樱桃沟游览区生态条件的变化及城市化对植物生长发育的影响。两个功能区的气温、相对湿度、降雨量以及雨水、飘尘、植物中的污染物质含量都有很大差异。工业区大多数植物的开花期、结果期比游览区早，而营养结束期延晚；有些植物甚至不能开花、结果；有些虽能正常开花，但花的数量少，结的果实也小等；游览区九种乔木、灌木的叶面积和四种常绿乔木的枝条年生长量都比工业区大0.5—1倍。

| Abstract: | The ecological conversion and effect of urbanization on growth of plants based on the data from two function areas, the Cherry Gully Sight-seeing area and the area of the Capital Steel industry are studied in this paper. The results showed that there are great differences in air temperature, relative humidity. precipitation and the contents of pollutants in rain, dust and plants between the two function areas. The blomingand fruit-bearing period of most plants in industrial area are earlier but the leaf changing-color period is later than those in Sight-seeing area. Some plants couldn’t even blossom and bear fruit. Although some plants could blossom but the flowers were less in number and their fruits were smaller. The leaf surface area of nine broad leaf’ trees and shrubs and the yearly twig growth rate of four evergreen needle leaf trees growing in Sight Seeing area were 0.5—l times as big as those in industrial area. |
