极端天气对绿地植物的影响及应对措施

Effects of Extreme Weather on Green Plants and Countermeasures

观测表明,全球气候变暖对全球许多地区的自然生态系统已经产生了影响,如海平面升高、冰川退缩、冻土融化、河(湖)封冻期缩短、中高纬生长季节延长、植物分布范围向南北极区和高海拔区延伸、某些植物数量减少、一些植物开花期提前等。本文总结了极端天气如高温天气、低温胁迫、强降雨对绿地植物的影响及处理措施,以期为绿地植物的栽培管理提供参考。

Observations show that global warming on natural ecological system in many areas of the world has impacts, such as sea level rising, glacier retreating, permafrost melting, river （lake） freezing period shortening, middle-high latitude growing season extending, distribution of plants extending to the north and south polar regions and high elevations, the decrease in the number of certain plants, some plants flowering period in advance and so on. Effects of extreme weather on green plants and countermeasures were summarized, such as high temperature ,low temperature stress and heavy rainfall, so as to provide references for the cultivation and management of green plants.
