近年来,我国城市绿化取得了前所未有的成就,城市环境质量明显改善。各城市都将园林绿化作为经营城市的重要手段,市民是直接受益者。在领导的重视和园林工作者的辛勤工作下,各城市的空气质量、环境质量和市民的活动场所均大为改观。但由于气候因素及生物入侵,使园林植物病虫害传统的地理分布格局发生了巨大变化,园林病虫害防治的传统理念受到挑战,造成了经济上的巨大损失。而这种损失在时间上是不可弥补的,该损失目前还没有得到足够的重视。园林植保工作者对此要保持清醒认识,积极应对。
In recent years, China’s urban afforestation has made unprecedented achievements, and the quality of urban environment has been significantly improved. All cities regard landscaping as an important means of operating a city, and citizens are the direct beneficiaries. With the leadership’s attention and the hard work of garden workers, the air quality, environmental quality and public activities of all cities have greatly changed. However, due to climate factors and biological invasion, the traditional geographical distribution patterns of plant diseases and pests have undergone tremendous changes. The traditional concepts of pest control in gardens have been challenged, resulting in enormous economic losses. However, this loss is irreparable in time and the loss has not been given enough attention at present. Garden plant protection workers should keep a clear understanding of this, and actively respond.
