摘    要:延安林区共有地栖鼠类8种,分属2科6属。密度和生物量在反映不同生境鼠类作用大小方面并不一致,本文利用密度和生物量综合决定的重要值来表示鼠类优势度,分析了该区地栖鼠类组成及作用大小,并对不同生境中鼠类的优势度水平进行了比较。指出中华鼢鼠是该林区的优势种类,并提出了针对该鼠的造林建议。

关 键 词:延安林区  鼠类  优势度  生境  重要值

Abstract:Eight species under 2 families and 6 genera of the geocole rodents were discovered in Yan'an forest region.The density and biomass are different in reflecting role of rodent in different habitats.The importance value determined by density and biomass was used to analyse the role and composition of rodents and comparative analysis had been carried through on the dominance of the rodents in different habitats. Myospalax fontanieri cansus is dominant in this region.Some proposals about harmful rodents prevention in forest regions are put forward.
Keywords:Yan'an forest region  rodent  dominance  habitat  important value
