摘要

在城市社区和土地利用的背景下,对代顿的植被配置特征进行了初步测量。结果表明,58%的城市土地未被人工表面覆盖,37%(近2500公顷)的非表面土地被树冠覆盖。这座城市有近2平方公里的裸露土壤。只有单户和两户住宅用地的树木覆盖面积大于草地覆盖面积,但这类用地也具有最大的树木覆盖增加空间。在整个城市和不同的土地利用方式中,土地覆盖特征存在很大差异。结果表明,通过扩大城市林业管理,有可能增加与树木有关的效益。

Urban forest of Dayton, Ohio: A preliminary assessment

Preliminary measurement of the characteristics of Dayton's vegetation configuration is provided in a context of the city's neighborhoods and land uses. Results show that 58% of the city's land is not covered with artificial surfaces, and that 37% (almost 2500 ha) of the non-surfaced land is covered with tree crowns. The city has nearly 2 km2 of exposed soil. Only single and two-family residential land use has more area with tree cover than grass cover, but this land use category also has the greatest available space for increasing tree cover. Wide variations in land cover characteristics exist throughout the city and across its land uses. Results indicate a great potential for increasing tree-related benefits through broadened urban forestry management.
