摘要
从１９４９年开始，我国森林害虫治理策略发展的第一个时期已经过去，第一个时期包括了三个阶段，即害虫防治（１９４９～１９６３）、协调防治（１９６３～１９８０）、综合治理ＩＰＭ（１９８０～１９９６），ＩＰＭ由于融合了生态学理论，是该时期的治虫策略发展的最高阶段，但它是以杀虫剂治虫为基础的。第二个时期即虫害的可持续控制ＳＰＭ时代的到来（１９９６），它的产生是国家的林业可持续发展及害虫治理中迫切需要解决的难题共同作用的结果。ＳＰＭ是建立在生态体系这个基础上的治虫策略，这是治虫理论上的变革，但急需研究和解决的问题包括：昆虫群落多样性测度ＩＣＤＭ，虫害频度ＰＦＩ，多样性测度阈值ＤＴＶ。
Started from 1949, the strategy for forestry pest management has passed the first period in China. The first period includes 3 phases :pest control(1949-1963), integrated control (1963～1980), integrated pest management (IPM) (1980～1996).IPM was the highest phase characterized with the combination of ecological theory and insecticides. The second period started from 1996, sustainable pest management in forestry (SPM),was promoted by countrys policies of sustainable development forestry and the difficulties to be overcomed in pest management. SPMs substructure was ecosystem . This is an innovation about theory of pest management. Above all, problems to be studied and solved are as follows:insect community diversity measurement (ICDM),pest damage frequency intensity (PFI, which could be used to compare the differences among main pest species, drgrees of damage and periods for damage in various stands),insect community diversity measurement threshold value(a critical value at which pest damage occurs or does not occur in special habitat).
