Brown field
问题描述：
Brown field
答
首先,Brownfield本身是一个地名.
其次,这个单词的英文意思是：A piece of industrial or commercial property that is abandoned or underused and often environmentally contaminated,especially one considered as a potential site for redevelopment.中文意思是：棕色地带,就是有污染的土地,指工厂关闭之后所闲置的土地,往往是被污染的土地.再加个site跟这也没啥区别!
