摘　　要：抬田造林杨-农(油)-渔复合经营模式对杨树蛀干天牛虫口密度和有虫株率都有明显下降作用。其生态控制的综合效益有以下几方面:(1)促进了杨树的快速生长,提高了杨树迅速生长的经济效益;(2)增加了抬田垛面林下套种农作物和沟内养殖水产品的收入;(3)增加了杨树林内有益生物的多样性;(4)对天牛类蛀干害虫起到了有效地控制作用;(5)天牛严重危害区可合理间种柳树(诱集天牛),并在天牛虫口密度达到饱和时,及时集中防治或消灭高虫口密度虫源诱集树(柳树)上的蛀干害虫天牛,可达到控点保面的作用。Poplar-agriculture （oil）-fishing compound management system has an obvious reducing function to trunk longicorn of poplar in afforestation by lifting the field. The density of longicorn and ratio of larva stricken trees have declined obviously. The ecological eontroling effects are as follows： ①promoting poplar＇s fast growth, improving economic efficiency; ②Increasing income of the interplanting crops under afforestation of lifting field and the aquatic product in ditch;③Increasing bio-diversity in the forest; ④Controlling effectively to trunk longicorn of poplar. The reasonable interplanting of tempting trees （eg. willow） in the seriously damaged area by longieorn facilitates to control and clean up promptly the pest species when its density achieves saturation, to eliminate the source of trunk longicorn in order to achieve the function of control spot and guarantee-the-surface.
