Unit 1

Urban forestry involves(refers to / is concerned with) forestry activities introducing forestry from wild lands (fields) and countryside (rural regions) to populous cities where economy, culture, industry and business (commerce) are concentrated. Most metropolitan cities are currently prosperous but noisy (clamorous) with deteriorating ecological environment. People living in such a crowded and narrow city space suffer from a worsening (declining) physical quality. To develop urban forestry can beautify environment, purify air, reduce noise and adjust local climate (microclimate), so that the living quality of urban people can be improved. Generally, urban forestry has provided a new approach to the urban environmental problems.

社区的物质框架结构被称为它的基础设施。这些在城市里发挥作用的庞然大物可以被分为绿色和灰色两种。绿色结构是为乔木、灌木、草地所覆盖的区域，而灰色结构指建筑、道路、公用事业设备、停车场的所在。绿色结构是渗水的，土壤让水渗进去，自然地过滤掉污染物，然后水进入河流。灰色结构却不能穿透，它迫使水走向地面，入河之前一定要经过处理和清洁。

作为城市绿色结构的树木，它们的作用和灰色结构不同，但尚无充分文字记载。由于树木没有量化的价值指标，因此没有把它们考虑进预算程序之中。城市绿色结构的大小、形态、方位可以被度量，它们在公用事业中发挥的作用可以进行准确计算。

尽管灰绿结构对一个城市都很重要，但利用土地尽力营造绿色结构的社区就能避免更多污染物，使运营成本效力更高，因此更宜居住。不过对于地方政府管理者来说，平衡灰色和绿色结构就成为一个很严重的挑战。
