| 目的 探讨2001-2013年河北省长爪沙鼠疫源地长爪沙鼠密度在不同年份、月份和生境上的分布及其相互间关系。方法 对2001-2013年河北省国家级和省级两个长爪沙鼠疫源地相关长爪沙鼠监测数据进行分析；以年为观察单位，定义鼠密度≥1.00只/公顷时为高危年组、0.20～1.00只/公顷时为预警年组、≤0.20只/公顷时为标准年组，采用Kruskal-Wallis H秩和检验按年份组比较长爪沙鼠生境、月份分布的差异，并对这些变量进行多重对应分析。结果 2001-2005年河北省长爪沙鼠疫源地连续5年长爪沙鼠密度>1.00只/公顷，2005年之后长爪沙鼠密度呈下降趋势，但2008和2013两年长爪沙鼠密度在0.20～1.00只/公顷之间。生境分布分析显示，3个年份组的不同生境长爪沙鼠密度分布均不同，差异有统计学意义（P<0.05），3组鼠密度M均为耕地最高，而高危年的荒地极大值最高，为20.50只/公顷。月份分布显示，高危年和标准年的不同月份鼠密度分布不同，差异有统计学意义（P<0.05），而预警年鼠密度月份分布差异无统计学意义。多重对应分析可见动物鼠疫高危年与荒地、4月份和6月份有较强聚集；预警年与耕地、7月份有关联。结论 河北省长爪沙鼠疫源地长爪沙鼠鼠密度>1.00只/公顷时提示动物鼠疫流行的危险性增加。应根据长爪沙鼠的分布特点，对耕地和荒地以及4和6月份加强监测，防止动物鼠疫的流行。 |

| Objective To explore the yearly, monthly and habitat-related distribution and their relations with Meriones unguiculatus density in the Hebei Meriones unguiculatus plague foci, from 2001 to 2013. Methods Data related to Meriones unguiculatus was gathered through the monitoring programs set up at the national and provincial Meriones unguiculatus plague foci in Hebei province, from 2001 to 2013. According to the yearly density of Meriones unguiculatus, criteria set for the three groups under study, were as follows:‘high-risk group’ -when the rodent density was≥1.00 under rodents/hm2, ‘warning group’-when the rodents/hm2 > rodent density > 0.20, ‘standard group’-when rodents/hm2 rodent density≤0.20 rodents/hm2. Differences of habitats and monthly distribution among the three groups were compared, under the Kruskal-Wallis H rank sum test while their relations were under the multiple correspondence analysis. Results The Meriones unguiculatus densities were higher than 1.00 rodents/hm2, far above the set national standards, in the monitoring area, between 2001 and 2005. From 2005, though the rodent densities began to decrease, however, figures from 2008 to 2013 were still among 0.20 to 1.00 rodents/hm2. The distribution of habitats in the three groups showed that the Meriones unguiculatus densities were all different in habitats and the difference was statistically significant (P<0.05). The highest median densities were all in the arable land, with maximum value of high-risk group appeared the highest (20.50 rodents/hm2) in the wasteland. Monthly distribution showed that the Meriones unguiculatus densities were different and the difference was statistically significant (P<0.05) in the high-risk and standard groups but not statistically significant in the warning group. Data from the multiple correspondence analysis showed that there was a strong aggregation among wasteland, in April and June, while the warning group was associated with weather in July and the arable land. Conclusions When the density became higher than 1.00 rodents/hm2, the risk on animal plague increased in Hebei Meriones unguiculatus plague foci. Based on the distribution of Meriones unguiculatus, programs should be set to monitor the rodent in arable land and wasteland, in April and June, to reduce the prevalence of animals plague. |
