摘　　要：【目的】揭示大型土壤动物群落特征与不同类型景观驳岸生态因子间的联系,以期为未来城市景观驳岸的建造以及生态环境修复与保护提供一定理论参考。【方法】采用实地调查法和数据分析法,对成都市温江区江安河、杨柳河及金马河3条河流不同景观驳岸类型大型土壤动物群落特征进行了研究。【结果】共捕获大型土壤动物1252只,隶属于27目117科。不同类型景观驳岸大型土壤动物密度存在显著差异(P<0.05),类群数与个体密度均呈现混合型驳岸>自然型驳岸>硬质型驳岸;大型土壤动物季节动态存在显著差异(P<0.05);大型土壤动物类群数和个体密度总体呈现秋季显著高于其他季节的趋势(P<0.05),而其余季节之间无显著差异(P>0.05)。【结论】不同景观驳岸大型土壤动物群落多样性有显著差异。建议在建造园林景观驳岸时,应注重驳岸材料的选择,适当保留原有植被,充分发挥景观驳岸的生态、观赏等功能。【Objective】This study was designed to reveal the connection between the characteristics of soil macrofauna communities and the ecological factors of different landscape revetment types,and provide theoretical references for the construction of urban landscape revetment and the restoration and protection of ecological environment in the future.【Method】The characteristics of soil macrofauna communities of different landscape revetment types in three rivers,Jiang′an,Yangliu and Jinma Rivers,Wenjiang District,Chengdu were studied by employing the method of field investigation and data analysis.【Result】A total of 1252 soil macrofauna were captured in this experiment,belonging to 27 orders and 117 families.The analysis results showed that there was a significant difference(P<0.05)among three different revetment types,both the group number and the individual density showed mixed-type revetment>natural revetment>hard-type revetment.There was a significant difference(P<0.05)among different seasons of soil macrofauna;the group density and the individual number of soil macrofauna in autumn were significantly higher than in other seasons(P<0.05),while there was no significant difference between other seasons(P>0.05).【Conclusion】The diversity of soil macrofauna communities on different landscape revetment is significantly different.Therefore,when constructing the landscape revetment,it is better to pay attention to the selection of revetment materials,properly retain the original vegetation,give full play to the ecological and ornamental functions of the landscape revetment.
