摘要：为了解不同植被恢复模式对土壤纤毛虫群落特征的影响,于2011年10月至2012年9月用"活体观察法"和"三级十倍环式稀释法"对定西市巉口林业试验场3种不同植被恢复模式(云杉林、杨树林、混交林)和不同恢复阶段的土壤纤毛虫群落进行了研究。共鉴定到141种纤毛虫,隶属于3纲10目37科50属。结果表明,不同植被恢复模式样点的土壤纤毛虫群落特征存在明显差异,混交林群落最优,而杨树林最差,纤毛虫物种数、丰度、物种多样性及群落组成的复杂性都表现为混交林>云杉林>杨树林。随着植被恢复时间的延长,云杉林和混交林纤毛虫群落结构趋于复杂化,物种数、丰度和物种多样性均呈现出明显的上升趋势,而杨树林相反。结果显示,混交林恢复模式大大改善了该区土壤环境质量,使得纤毛虫群落结构不断优化,更有利于该区生态环境的恢复重建。
In order to understand the effect of different soil ciliates, a study of soil ciliate communities across vegetation restoration patterns on communities characteristics of three kinds of different vegetation restoration patterns （spruce, poplar forest, mixed forest） and different recovery stages was undertaken using live observation ciliates and ＂the three level ten-fold dilution method＂ in Dingxi Chankou forestry experimental farm from October 2011 to September 2012. A total of 141 species were identified, belonging to 3 classes, 10 orders, 37 families and 50 genera. The results showed that the community characteristics of soil ciliates had obvious differences among the various sampling sites of different vegeta- tion restoration patterns, the community structure of soil ciliates was the most complex in mixed forest and it of poplar forest was the most simple, and species richness, abundance and species diversity index showed the succession of mixed forest〉spruce 〉poplar forest. With prolonging of restoration years, the community structure of soil ciliates tended to be complicated, and species richness, abundance and species diversity index showed an obvious upward trend in the spruce and mixed forest, but them of poplar forest showed a contrary trend. The results shows that the restoration patterns of mixed forest greatly improved the soil environment quality and optimized the community structure of soil ciliates, and had advantages to restoration and reconstruction of ecological environment in this region.
