为期171天的2016唐山世界园艺博览会正在举行。借助绿色办世园的契机,唐山作为传统的“钢铁重镇”壮士断腕、压减产能、重拳治霾,多措并举促产业升级,积极探索实践绿色转型的蜕变之路。不占耕地“都市和自然”是历届世园会关注的话题。唐山赢得国际园艺生产者协会信任的一个重要原因,就是世园会会址不占用耕地,完全利用采煤沉降区。从 The 171-day 2016 Tangshan World Horticultural Exposition is underway. Taking advantage of the opportunity of running a green park, Tangshan, as a traditional “steel-heavy town”, has cut down on its production capacity and cut heavy haze. It has also taken measures to accelerate industrial upgrading and actively explored the transformation path of practicing green transformation. Not occupying arable land “City and nature ” is the theme of all previous World Parks. An important reason why Tangshan won the trust of the International Society of Horticultural Producers is that the site of the Horticultural Exposition will not occupy cultivated land and make full use of the coal mining subsidence area.
