摘　　要：在采用网格法对华北平原及黄土高原啮齿动物调查的基础上，分析了啮齿动物物种丰富度空间格局。华北平原物种丰富度最低，其次为晋、翼山地和汾、渭谷地，而南蒙高原和黄土高原的丰富度较高；物种丰富度纬向变化不明显，而经向变化显著，由东向西，物种丰富度呈递增趋势；丰富度在海拔上的变化并不存在相关的地理模式；丰富度与山地面积呈正相关，与平原面积呈负相关，而与丘陵面积相关不显著，丰富度与各地地貌类型面积的总和呈明显的正相关；丰富度与温度相关不明显，而与降雨量呈负相关。在华北平原及黄土高原，生境结构类型愈复杂的地区，啮齿动物物种丰富度愈高。The relationships between the spatial pattern of rodent species richness and environment factors were analysed based on wild survey in North China plain and Loess plateau from 1992 to 1994, using quadrates method and living trap as the primary means of data collection . The results showed that: There are the more species richness of rodent in Nanmong Plateau (northernest Shaanxi and southernest Inner Mongolia) than that of Fen, Wei rivers basin of Shaanxi and Shanxi and also Hebei Mountainous area, but there are the most lowest species in Huabei Plain. The correlation analysis showed that: Species richness does not appear to the increase of latitude and altitude changes ,but obviously positive correlated with longitude increase; species richness, positively correlated with area of mountain, not obviously correlated with hills, the most obviously positive correlated with total area of landscape types ,by contrast, negatively correlated with area of plain; richness is not obviously correlated with temperature, but negatively correlated with fall rain. Based on our data ,the species richness of rodents is determined by the degree of complicates of habitat types.
