摘　　要：探讨了做好稻田蜘蛛越冬保护和增加稻田斑块异质性对稻田蜘蛛群落重建的作用及稻田蜘蛛多样性的影响。结果表明，做好稻田蜘蛛的越冬保护和增加早稻田斑块异质性有利于早、晚稻田蜘蛛群落的重建，使早、晚稻田蜘蛛群落重建的速度分别加快8天和7天。同时也能维持蜘蛛群落较高的物种多样性，为防止水稻害虫的早期爆发创造了条件。The effects of overwintering protection of spiders and rational distribution of early- mid late-ripe season rice on spider community restablishment in rice field wereresearched. The results showed that these measures could quicken community reestablishment＇s steps for 7-8 days. At the same time, they could maintain a larger species diversity office field spider community. The reestablishment of spider community in paddy fields was a dynamic process.
