| 摘 要： | 1997年对内蒙古鄂尔多斯沙地中的 3种优势啮齿动物 (小毛足鼠 Phodopusroborovskii、三趾跳鼠 Dipus sagitta和子午沙鼠 Meriones meridianus)及常见种 (黑线仓鼠Cricetulus barabensis)的种群生产量进行了研究 .这 4种鼠种群生产量均表现出明显的季节变化 ,其季节动态特点是由其季节性繁殖特性及各季节的种群数量所决定 .小毛足鼠、子午沙鼠和黑线仓鼠的繁殖生产量约占其种群生产量的一半 ( 44～ 4 7% ) ;而三趾跳鼠的繁殖生产量占其种群生产量的 1 4 % ,这与该鼠的低繁殖率有关

| Abstract: | Population productions were studied for three dominant rodents ( Phodopus roborovskii, Dipus sagitta and Meriones meridianus) and one common species ( Cricetulus barabensis) inhabiting in Ordos sandland, NeiMongol in 1997. The main results and conclusions obtained are as: 1) There are obvious seasonal fluctuations for population productions of the four species, which are determined by their reproduction and population size of each season. 2) For productions due to reproduction,they are almost half (44%~47%) of the population productions in Phodopus roborovskii,Meriones meridianus and Cricetulus barabensis, but it is only 14% of the population production in Dipus sagitta which may be caused by low reproductivities. |
