摘要
园林和森林存在很大差异,它有很大的人为因素,因此生态比较脆弱。防治害虫所使用的化学农药多且不合理,治理上没有长远打算,致使危害不断发生,这是目前普遍存在的现状。今后应在尊重生态规律的前提下,抓好园林几种主要害虫生命表的研究,建立预测预报模型,防治前确定虫害的经济阈值,找出适宜的决策依据,建立害虫综合动态模型和生态综合管理体系,最终达到自然控制的目的。
Landscape architecture differs from forest in its artificial elements to a greot extent, and the ecology there is frogiie. Greot omaunt of the pesticides ore used irrotianoiiy ond no long-term pion is mode in treotment, which couse the pest domoge hoppen ceoseiessiy, o common stotus in iondscope orchitecture ot present. It is proposed thot the ecologicol lows should be volued, ond the study of the life-tobies of moin pests should be conducted ond the forecosting models should be estoblished. The economic threshold volue of pests should be defined before treotment and provide oppropriote basis for decision-rooking. The comprehensive dynomic pest domoge models and comprehensive ecological monogement system should be established, finolly reoching the notural control torget.
