通过聚类分析和主成分排序,陕北林地啮齿动物群落被划分为3个类型。吴旗林区的啮齿动物群落是典型的黄土高原风沙区林地群落类型,种类较多,密度变化较大,优势种为中华鼢鼠和跳鼠类。对林木造成巨大危害的种类主要为中华鼢鼠和草兔。退耕林地啮齿动物群落保持了原农田群落的特点,其桥山林区的群落优势种是甘肃鼢鼠,而吴旗林区退耕林地为中华鼢鼠。桥山林地啮齿动物群落种类和生物量因植被状况较大差异,天然次生林种类较少,密度较低,优势种是达乌尔黄鼠和松鼠类。灌木疏林林地群落兼有天然次生林的啮齿动物群落和农田啮齿动物群落的特性,优势种为达乌尔黄鼠和松鼠类。次生林全面清坡造林幼林地,其群落优势种为甘肃鼢鼠。
By clustering analysis and principal component ranking, the rodent communities in northern Shaanxi were divided into three types. The rodent community in Wuqi forest area is a typical type of forest community in windy and sandy area of the Loess Plateau, with more species and more density variations. The dominant species are Chinese zokor and jerk. The species that cause great damage to trees are mainly Chinese zokor and grass rabbit. The rodent communities in the returned farmland maintained the characteristics of the original farmland community. The community dominant species in Qiaoshan forest area were Zokor both in Gansu Province and the returning farmland in Wuqi Forest Region was Chinese zokor. The species and biomass of rodent communities in Qiaoshan mountainous forest are quite different because of their vegetation status. There are few natural secondary forest species and low density. The dominant species are Daurian ground squirrel and squirrel. The characteristics of rodent and farmland rodent communities in both shrub-woodland and natural secondary forests are Daullina and Squirrels. Secondary forest full slope slope afforestation young forest land, its dominant species of gansu zokor.
