Unit 1 Urban Agriculture 的

城市林业是把林业由野外、农村引进人口稠密的经济文化与工商业集中的城市的林业活动。目前大多数城市繁华、喧闹、生态环境恶化,生活在拥挤狭小的城市空间里的人们身体素质下降。发展城市林业可以美化环境、净化空气、减少噪音和调节小气候,改善城市人的生活质量。城市林业为解决城市的环境问题提供了一种新的途径。
Urban forestry involves (refers to / is concerned with) forestry activities introduced from wildness and countryside to populous cities where economy, culture, industry and business (commerce) are aggregated (clustered). Most metropolitan cities are currently prosperous but noisy (clamorous) with deteriorating ecological environment. People living in such a crowded and narrow space suffer from a worsening physical quality. To develop urban forestry can beautify living places, 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.

B. 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。
Unit 2 Forestry Management 的

随着人类社会的经济发展与文明进步,人们对森林的认识有了重大转变,社会对林业的需求也发生了很大的变化,森林维护与改善生态环境的功能在世界范围内得到了广泛的重视和关注。1992年联合国召开的环境与发展大会上以赋予林业以首要地位为最高级别的政治承诺,并特别强调在世界最高级会议要解决的问题中,没有任何问题比林业更重要了,将林业问题提到前所未有的高度,这是世界文明发展史上的一个重要的里程碑。
With the development of both economy and civilization in human society, people have greatly improved their knowledge and understanding about forests. They therefore have also dramatically changed their social demands for forestry. As a result, more world attention has been widely paid to the function that forests play to maintain and improve environment. In 1992, UN Conference on Environment and Development bestowed priority on forestry and it became a political promise of th
