摘要
采用植物生长指数和空间排序法,研究扬州市6个具有代表性的城市绿地树种的生长状况及其空间构成特点。结果表明:绿地群落中生长指数大于60的树种有57个,其中生长指数大于70的基调树种有34个(包括骨干树种10个),生长指数小于70的一般树种有23个;在空间构成上,生态关联不明显,树种多样性配置不充分,绿地类型欠丰富。
The relative disposition of treespecies from the six urban afforestations in Yangzhou city by using plant growth index and airspace array. The results were as follows: there were 57 treaaspecies with plant growth index >60 in the urbon afforests. The fundamental treaspecies with plant growth index >70 were 34 (including 10 dominant trees), the ordinary trees with plant growth index <70 were 23. In the space construction the biological relation was not obvious, the tree variety was not abundant, the airspace type was not affluent.
