本文提出随着现代城市发展的客观要求,促使园林发展的必然趋势是建设城市大园林,城市大园林的主要特点是规模大、生态平衡和可持续性发展。园林植物病虫害防治工作作为城市园林绿化养护管理的重要组成部分,理所应当顺应城市大园林发展建设,维系大自然的整体秩序,恢复生态平衡。以往采用大量化学农药防治病虫害,造成杀伤天敌、污染环境、损害人们身心健康、导致恶性循环和次要害虫上升为危险性害虫的严重后果。只有采用无农药污染,以生物防治为主的病虫害综合治理,才能顺应城市大园林发展的必然趋势,以维护城市生态平衡,缔造出优美、自然、和谐的城市环境,使城市得以可持续发展。
This paper proposes that with the objective requirements of the development of modern cities, the inevitable trend of promoting the development of gardens is to build large urban gardens. The major characteristics of large urban gardens are large-scale, ecological balance and sustainable development. Garden plant pests and diseases prevention and control work as an important part of urban landscaping conservation and management should go along with the development and construction of large urban gardens, maintain the overall order of nature and restore ecological balance. In the past, a large number of chemical pesticides were used to control pests and diseases, causing natural enemies, polluting the environment, damaging people’s physical and mental health, leading to vicious cycles and the rise of secondary pests to dangerous pests. Only by adopting pesticide-free pollution-based comprehensive management of pests and diseases with biological control can we adapt to the inevitable trend of the development of large urban gardens in order to maintain the urban ecological balance and create a beautiful, natural and harmonious urban environment so that the city can be built sustainably.
