【摘要】：【目的】对广西喀斯特地区甘蔗园土壤动物群落多样性进行调查,了解其多样性特征及季节动态规律,为指导喀斯特地区开展甘蔗科学种植和充分发挥喀斯特土地潜力提供基础资料。【方法】2012年3月~2013年2月采用手捡法、干漏斗法和湿漏斗法逐月12次对广西喀斯特地貌下甘蔗园土壤动物群落多样性进行调查。【结果】全年捕获土壤动物5090只,隶属于3门10纲20目23类,其中,优势类群为弹尾目(53.08%)、蜱螨目(18.84%)和泄管纲(15.99%),常见类群为双尾目(2.24%)、膜翅目(1.93%)、双翅目幼虫(1.69%)、颤蚓目(1.59%)和蜘蛛目(1.12%)。甘蔗园土壤动物类群数季节动态为:秋季冬季春季夏季,个体数季节动态为:秋季夏季春季冬季,多样性季节动态为:秋季春季夏季冬季。【结论】广西喀斯特地区甘蔗园土壤动物群落优势类群为弹尾目、蜱螨目和泄管纲3类,常见类群和稀有类群多度较低,群落多样性的季节变化受自然环境变化和人类耕作活动的双重影响,具有自身的特点和规律。
[Abstract]:[objective] to investigate the diversity of soil animal communities in sugarcane orchard in Karst region of Guangxi, and to understand the characteristics of diversity and seasonal dynamics. To provide basic information for guiding scientific cultivation of sugarcane in karst area and realizing the full potential of karst land. [methods] hand picking method was adopted from March 2012 to February 2013, Dry funnel method and wet funnel method were used to investigate the diversity of soil fauna community under karst landform in Guangxi 12 times a month. [results] 5090 soil animals were captured in the whole year, belonging to 3 phyla, 10 classes, 20 orders and 23 classes. The dominant groups were phyloptera (53.08%), acariidae (18.84%) and ejaculata (15.99%). The most common groups were Diptera (2.24%), Hymenoptera (1.93%), Diptera (1.69%), Chrylostoma (1.59%) and Araneae (1.12%). The most common groups were Diptera (2.24%), Hymenoptera (1.93%), Diptera (1.69%) and Araneae (1.12%). The seasonal dynamics of soil animal groups in sugarcane orchard were autumn, winter, spring and summer, and individual number seasonal dynamics were autumn, summer, spring and winter. The seasonal dynamics of diversity are as follows: autumn, spring, summer and winter. [conclusion] the dominant groups of soil fauna community in sugarcane orchard in Karst region of Guangxi are Elastomidae, acariidae and ejaculation, and the abundance of common and rare groups is low. The seasonal variation of community diversity is influenced by both natural environment change and human farming activity and has its own characteristics and laws.
