Abstract:
Objective To study the impact of farmland climate factors on the rodent community. Methods From 1978 to 1993, canonical correlation analysis of the farmland rodent density and climate factors in Kaijiang county, Sichuan province was conducted. Results In the period, the overall farmland rodent density was 5.58%-26.57% ; Apodemus agrarius density 1.91%-18.41% , Rattus norvegicus density 0.68%-10.86% , and Anourosorex squamipes density 0.47%-9.50% . Among the canonical correlation coefficients between 12 climate factors including temperature, humidity, rainfall and sunshine, and four variables (overall rodent density, Ap. agrarius density, R. norvegicu density, An. squamipes density), the first couple (correlation coefficient r=1.0000) was statistically significant (χ2=248.7032,P<0.01). The largest coefficient of the rodent density was noted in the overall rodent density (4.7748), and the largest coefficient of the climate factors was the average sunshine from July to August (-3.1532), followed by average humidity from July to August (-1.6177) and then average rainfall from July to August (-1.4652). All were negatively correlated. Conclusion Farmland rodent quantity was mainly affected by average sunshine, humidity and rainfall from July to August.

摘要:
目的 探讨气象因素对农田鼠类数量的影响。方法 采用典型相关分析对开江县1978-1993年农田鼠密度与气象因素进行统计分析。结果 1978-1993年开江县农田总鼠密度为5.58%~26.57%,黑线姬鼠、褐家鼠、四川短尾鼩密度分别为1.91%~18.41%、0.68%~10.86%、0.47%~9.50%。气温、湿度、降雨量、日照数等12种气象因素与总鼠密度,黑线姬鼠、褐家鼠、四川短尾鼩密度4个因变量的典型相关系数中,第1对(r=1.0000)有统计学意义(χ2=248.7032,P<0.01),鼠类数量以总鼠密度标准系数最大(4.7748),气象因素标准系数最大的依次为7-8月平均日照数(-3.1532)、7-8月平均湿度(-1.6177)和7-8月平均降雨量(-1.4652),且全部为负相关。结论 农田鼠类数量主要受7-8月平均日照数、平均湿度和平均降雨量的影响。
