几年来,在各级领导的重视和园林工作者的辛勤工下,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。
Over the past few years, the attention of leaders at all levels and the hard work of garden workers have greatly improved the air quality, environmental quality and public activities of the city. However, due to climate factors and biological invasion, the traditional geographical distribution patterns of plant diseases and pests have undergone tremendous changes. The traditional concept of prevention and control of plant diseases and pests has 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.
