摘要: 【目的】研究干旱区土壤环境因子对土壤螨类群落多样性的影响,对鄯善县7种不同生境进行土壤螨类群落调查与环境因子测定。【方法】采用改良的Tullgren法分离收集土壤螨类,并用Pearson相关分析和典范对应分析方法对土壤螨类群落多样性特征及其与环境因子之间进行相关分析。【结果】共捕获土壤螨类成体标本26 637只,隶属于4目69科98属。7种不同生境之间土壤螨类群落多样性指标均有极显著差异(P<0.001),其中Shannon-Wiener多样性指数(H)依次为防护林>葡萄园>杏园>苜蓿地>草地>耕地>菜地。CCA分析结果表明,第一主轴和第二主轴分别解释了土壤螨类主要群落总变量的29.7%和17.1%,与环境因子的相关性系数分别为0.926和0.929,前两轴共解释了土壤螨类物种类与环境因素关系的92.9%。蒙特卡罗置换检验显示,10个土壤主要理化性质与第一排序轴(F=4.31,P=0.002)和全部排序轴(F=2.68,P=0.002)均存在极显著的相关性。【结论】鄯善县7种不同生境土壤螨类群落多样性与土壤含水量、有机质、容重及全氮含量呈显著相关(P<0.05),其中土壤含水量、全氮和有机质含量对螨类群落结构和多样性的影响显著。

Abstract: 【Objective】 In order to understand the effects of soil environmental factors on the diversity of soil mite communities in arid areas,the soil mite community survey and environmental factor determination were conducted at seven different habitats in Shanshan County in 2015.【Method】 The relationship between diversity of soil mite communities and seven environmental variables were analyzed by using multivariate regression analysis and canonical correspondence analysis method.【Result】 A total of 26,637 soil mite adult specimens were collected, and they belonged to 4 orders, 69 families and 98 genera. The diversity indexes of soil mites communities in 7 different habitats were significantly different (P<0.001). The order of Shannon - Wiener diversity index (H) was shelter forest > vineyard > apricot garden > alfalfa land > grassland > farmland > vegetable fields. The results of CCA analysis showed that the first axis and the second axis explained 29.7% and 17.1% of the total variables of the main community of soil mites, respectively, and the correlation coefficients of environmental variables were 0.939 and 0.918, respectively. The first two axes explained 92.9% of the relationship between the species of soil mites and environmental factors. The Monte Carlo replacement test showed that the ten main physic - chemical properties of the seven different habitats were significantly correlated with the first CCA axis (F=4.31, P=0.002) and all the axes (F=2.68, P=0.002).【Conclusion】 The diversity of soil mite communities was significantly correlated with soil moisture content, organic matter content, total nitrogen content (P<0.05), among which, the soil moisture content, total nitrogen and organic matter content were the main factors affecting the community structure and diversity of soil mites in that area.

Key words: soil mites; community diversity; environmental factors; CCA analysis
