摘要/Abstract

摘要： 土壤螨类群落监测是生态恢复监测的重要内容之一,土壤螨类群落结构的变化可以反映退化环境生态恢复的效果.2014年按季节对贵州省毕节市朝营小流域中度石漠化生态修复区的土壤螨类进行调查,并与原生栓皮栎林和中度石漠化区的土壤螨类群落结构进行对比.结果表明: 中度石漠化生态修复区土壤螨类计有3目35科58属,以单翼甲螨属和威单翼甲螨属为优势属;土壤上层具有较高的属数、个体数量和个体密度;捕食性革螨群落以r对策者为主,甲螨群落结构以有翅孔背甲螨型(P型)为主.中度石漠化生态恢复区土壤螨类个体数量与个体密度分别高于中度石漠化区和栓皮栎林,属数、多样性指数和丰富度指数分别高于中度石漠化区,但低于栓皮栎林;该区在对照区基础上恢复和新增螨类共32属,占该区螨类总属数的55.2%.在研究区,螨类属数与土壤速效钾含量、丰富度指数与有机碳含量具有显著相关性,个体数量、个体密度、多样性指数、丰富度指数分别与速效钾含量以及丰富度指数与有机质含量具有显著相关性.表明石漠化的植被修复有利于土壤螨类群落结构的恢复和土壤环境的改善,且螨类优势类群、新增类群和恢复类群能对环境变化进行较好地指示,但土壤螨类群落结构与修复区植被和土壤理化因子变化的关系还有待进一步研究.

Abstract: The monitoring of soil mite community is an important part of ecological restoration monitoring. Changes of community structure in soil mites could reflect effects of ecological restoration in degraded environment. In different seasons of 2014, we investigated soil mites in the moderate rocky desertification ecological restoration area of Chaoying small watershed in Bijie City, Guizhou Pro-vince. We compared the community structure of soil mites in native Quercus variabilis forest and moderate rocky desertification area. The results showed that soil mites in ecological restoration area of moderate rocky desertification belonged to three orders, 35 families, and 58 genera, with Haploze-tes and Vilhenabates being the dominant genera. Higher number of genera, abundance, and indivi-dual densities were found in upper soil layer. The community structure of predatory Gamasina mites was mainly r-selected, and that of Oribatida mites was mainly Poronota (P-type). In the moderate rocky desertification ecological restoration area, both the abundance and individual density of soil mites were higher than that in moderate rocky desertification area and Q. variabilis forest, while the number of genera, diversity index and richness index were higher than that in moderate rocky desertification area, but lower than that in Q. variabilis forest. On the basis of the control area, 32 genera of mites were recovered and added, accounting for 55.2% of the total number of mite genera in the restoration area. In the whole study area, the number of mite genera were significantly correlated with soil available potassium, richness index, and organic carbon content. The number of indivi-duals, individual density, diversity index, richness index separately had significant correlations with the content of available potassium. The richness index had significant correlation with the content of organic matter. Our results suggested that the vegetation restoration of rocky desertification was beneficial to the restoration of mite community and improvement of soil environment, and that the dominant groups, new groups, and restoration groups of soil mites could indicate environment changes. However, the relationships between soil mite community structure and vegetation, soil physical and chemical factors in the restoration area remained to be further studied.
