摘要: 通过对河北省曲周县盐渍化改造区农田生态系统中蚯蚓物种多样性分析,发现蚯蚓种群的次生演替与农田肥料投入有很好的相关性,合理的投入特别是有机肥的投入可以加速农田生态系统中生态演替;该地区蚯蚓种群分布总的趋势是:第2代试区>第1代试区>第3代试区>原貌区;不同土地利用方式蚯蚓的分布和数量各不相同,菜地>农田>边缘地和果园.

Abstract: The analysis on earthworm diversity in the farmland ecosystem of salinity transforming region in Quzhou County,Hebei Province,showed that the secondary succession of earthworm population had a close relationship with the input of fertilizer and manure.An optimum input,especially manure input,could accelerate the secondary succession.The general trend of earthworm distribution was in the order of second experimental district>first experimental district>third experimental district>original area.The distribution,biomass and amount of earthworm varied in different types of land use,and the relationship was in the order of vegetable field>crop field>orchard and margin land.
