中文摘要	【目的】揭示以潜在-轻度石漠化为主体和以中-强度石漠化为主体的喀斯特地区及其不同等级石漠化环境之间土壤螨类群落结构的差异。【方法】分别在以潜在-轻度石漠化为主体的高原山地区和以中-强度石漠化为主体的峡谷区采集潜在、轻度、中度和强度石漠化环境下的土壤螨类,通过标本鉴定和数据分析,判别不同环境下土壤螨类科、属、个体、捕食性螨类和甲螨生态类群以及群落多样性的差异。【结果】共捕获土壤螨类72科132属,甲螨是研究区土壤螨类组成的主体。中-强度石漠化喀斯特地区拥有丰富的螨类科和属;不同石漠化类型喀斯特地区螨类科、属的组成存在季节变化,随着石漠化程度的加剧,螨类科、属总体上逐渐减少;不同喀斯特区拥有不同的优势属群,且优势属的分布存在生境和季节差异;捕食性螨类和甲螨生态类群也随环境与季节的变化而变化;群落多样性指数以中-强度石漠化喀斯特区的稍高,但整体差异并不明显。【结论】不同石漠化主体类型喀斯特地区的土壤螨类群落结构存在差异,石漠化对土壤螨类群落结构造成影响,利用螨类优势属群可以对石漠化土壤环境进行初步指示,捕食性螨类和甲螨生态类群的分布与石漠化等级存在一定的不协调性,这种不协调性的机制有待进一步研究。
英文摘要	[Objectives] To quantify differences in soil mite community structure between karst areas with different degrees of rocky desertification. [Methods] We collected soil mites from sites with potential, light, moderate and intense rocky desertification from a mountain plateau with mainly potential-light rocky desertification, and in a canyon with mainly medium-intense rocky desertification. Differences in family, genus, species, ecological groups, and the community diversity of soil mites between these different environments were quantified and compared. [Results] Overall 132 genera of 72 families of soil mites were collected. Oribatid mites comprised the majority of soil mites in the research area. Families and genera of soil mites were more diverse in the medium-intense rocky desertification karst area. Community composition changed seasonally in different habitat types but the number of families and genera gradually reduced with increasing rocky desertification. Different dominant genera were discovered in two karst areas, moreover, their distribution changed with habitat and season. The relative abundance of predatory and oribatid mites groups varied with environment and season. The community diversity index was slightly higher at sites with medium-intense rocky desertification, but the overall difference was not obvious. [Conclusion] Soil mite community structure varies with different degrees of rocky desertification. This association means that the dominant genera can, to some extent, predict the degree of rocky desertification. However, the distributions of predatory and oribatid mites were uncorrelated with the degree of rocky desertification. The reason for this requires further investigation.
