Abstract:

【Objective】 Tto find out the effects of different land use type habitats on soil mite community diversity in agroecosystem at the southwest margin of Flaming Mountain in the hope of providing scientific basis for the protection of soil biodiversity, sustainable development and biological evaluation of environmental quality. 【Methods】 The diversity characteristics of soil mite communities in ten land use types of agroecosystem in the southwest margin of Flaming Mountain in Turpan were analyzed by field sampling and improved Tullgren method. The improved Tullgren method and morphological classification method were used to classify the soil mites and analyze the characteristics of community structure. 【Results】 A total of 21,195 soil mites were collected, belonging to 100 genera, 68 families and 4 suborders, among which, Protoribates was the dominant group, and Berniniella Balogh, 1983 and Monogalumnella Mahunka,1986 were newly recorded genera in China. There were significant differences in the number of individuals, groups and diversity indices of soil mites in different habitats of land use types (P< 0.05), in which the diversity of vineyards was the highest, while that of desert was the lowest. There were seasonal differences in community diversity, with the highest in autumn and the lowest in summer. The main predatory mites were K-selection type, and oribatid mites were O-type and P-type. 【Conclusion】 The results show that there are significant differences in the diversity indexes of mite communities among different land use types, and the main factors affecting the diversity of soil mite communities are surface litter and human disturbance.

Key words: agroecosystem; land use type; soil mites; community diversity

摘要:

【目的】研究火焰山南麓农业生态系统不同土地利用类型生境对土壤螨类群落多样性的影响,为农业生态系统土壤生物多样性保护提供科学依据。【方法】采用野外采样和改良的Tullgren法对吐鲁番火焰山南麓农业生态系统10种土地利用类型生境土壤螨类群落多样性特征进行比较分析。【结果】共采集土壤螨类 21 195头标本,隶属于4亚目68科100属,其中长单翼甲螨属Protoribates为优势类群,Berniniella Balogh,1983和Monogalumnella Mahunka,1986为中国新纪录属。不同土地利用类型生境土壤螨类个体数、类群数及多样性指标之间均有显著差异( P<0.05),其中葡萄园多样性最高,而荒漠最低;群落多样性存在季节差异,秋季最高,而夏季最低少。捕食性螨类以K选择型为主,甲螨主要为O型和P型。【结论】不同土地利用类型螨类群落多样性指标之间存在显著差异,地表凋落物和人为干扰是影响该区土壤螨类群落多样性的主要因素。
