摘要:
以喀斯特石漠化综合治理区典型的灌丛区、混农林区及其之间的自然恢复区作为研究对象,按等距离梯度设置样点并采样,用干漏斗法进行土壤螨类分离,通过群落多样性和边缘效应强度探讨混农林石漠化治理对土壤螨类多样性的影响,并探讨土壤螨类群落与环境因子间的相互关系,以期为石漠化治理的生态修复及生物多样性保护提供依据. 共获土壤螨类939头,隶属于3目37科65属,其中灌丛区捕获507头46属;混农林区292头30属;边缘区140头36属;派伦螨科(Parholaspididae)、缝甲螨科(Hypochthoniidae)和奥甲螨科(Oppiidae)分别占比25.56%、18.42%和18.10%,是该区土壤螨类的优势类群;卷甲螨科(Phthiracaridae)、尾足螨科(Uropodidae)和广缝甲螨科(Cosmochthoniidae)3科占比最少,均为0.11%,为该区土壤螨类的极稀有类群. 边缘效应强度从大到小依次排序为灌丛一侧边缘(1.0877)>边缘区(1.0685)>刺梨一侧边缘(1.0501);螨类多样性与土壤环境因子存在密切联系,该区对土壤螨类群落特征影响较大的环境因子是土壤有机质、土壤含水量、土壤容重和全钾. 本研究表明石漠化综合治理区土壤螨类较丰富,不同生境间螨类个体数、类群数均存在显着性差异;该边缘类型呈现正的边缘效应,总体边缘效应强度较弱;边缘区土壤螨类栖息重要的几个土壤环境因子含量最佳,灌丛一侧表现出最强的边缘效应.

Abstract:
This study is aimed to study the typical shrub areas, agroforestry areas and their marginal areas in the karst rocky desertification comprehensive management area, and to explore the effects of edge effects on soil mites diversity in order to control and repair rocky desertification a nd provide a basis for biodiversity conservation. The plots were set according to the equidistant gradient and sampled. The soil fungus was separated by the dry funnel method. The diversity, uniformity and edge effect intensity of the community were analyzed. A total of 939 soil mites were obtained in this study, belonging to 35 genera of 37 families of 3 orders, 4 suborders, 507 heads and 46 genera in shrub area, 292 heads and 30 genera in mixed forest area, and 140 head and 36 genera in marginal area. The results showed that Parholaspididae, Hypochthoniidae and Oppiidae accounted for 25.56%, 18.42% and 18.10%, respectively, which are the dominant groups of soil mites in this area; Phthiracaridae, Uropodidae, and Eohypochthonius accounted for the least proportion of the three families, all of which were 0.11%, which were extremely rare groups of soil mites in the area. The soil abundance index of each habitat showed shrub area > marginal area > agricultural forest area, and the diversity index and evenness index were all in the marginal area > shrub area > aggregated agroforestry area, and the dominance index was mixed agriculture and forestry area> Marginal area > shrub area. The edge effect intensity EH’ value is 1.0685, which shows a positive edge effect. The research indicates that the trend of the marginal zone of the soil in the shrub area and the agroforestry area is increasing, that is, the formation of the marginal zone is conducive to the increase of the diversity of the mites, but the EC value is less than 1, indicating that the edge positive effect intensity is not high. Changes in the intensity of edge effects in this area are subject to further monitoring.
