郑州市区和郊县（市）究竟有多少株大树、古树、珍稀树木？不得而知。以郑州市区为例，据郑州市绿化工程管理处负责人介绍，郑州市区现有古树存量极少。市人民公园内有一侏所谓的“古槐”，也只是本世纪20年代所值。棉纺路上有一侏大杨树，已干死。管城区内可能还有几株大槐树? Zhengzhou city and suburban counties (cities) how many strains of trees, old trees, rare trees? unknown. Take Zhengzhou City as an example. According to the person in charge of Zhengzhou Greening Project Management Office, there is very little existing ancient tree stock in Zhengzhou. City People’s Park there is a small so-called “ancient Huai”, it is only the value of the 20s of this century. Cotton road there is a jumbo poplar, has died. Tube City may have several strains of large locust tree?
