【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。更多还原

【Abstract】 Landscape architecture differs from forest in its artificial elements to a great extent, and the ecology there is fragile. Great amount of the pesticides are used irrationally and no long-term plan is made in treatment, which cause the pest damage happen ceaselessly, a common status in landscape architecture at present. It is proposed that the ecological laws should be valued, and the study of the life-tables of main pests should be conducted and the forecasting models should be established. The economic threshold value of pests should be defined before treatment and provide appropriate basis for decision-making. The comprehensive dynamic pest damage models and comprehensive ecological management system should be established, finally reaching the natural control target.更多还原
