摘要
根据田间系统调查把稻田节肢动物群落按营养和取食关系划分为三个营养层(基位物种、中位物种、顶位物种)和不同的功能集团,在物种、功能集团和营养层三个组织层次水平上分析了稻田节肢动物群落的结构和多样性。结果表明:三类稻田中,施生物药剂稻田的生态稳定性最好,自然稻田的生态稳定性好于施化学药剂稻田的生态稳定性。
The essay analyses the structure and diversity of the arthropod community in rice field, on the three organize administrative levels of the species, function group and nutrient class, according to systematic investigation and dividing the arthropod community in rice field into three nutrient classes （basal species, intermediate species, top species） and different guilds. Analysis result indicates： the ecological steady of biochemical rice field is the best, and the ecological steady of the natural rice field is better than the chemical rice field＇s.
