| 地下啮齿动物挖掘形成的土丘数量变化以及分布是其生态学研究的重要内容之一。传统的土丘数量和分布调查方法是计数法和填图法，存在工作量较大和误差较高等缺点。实时动态控制系统技术（RTK）是一种高精度的GPS测量方法，能够在野外实时得到厘米级的定位精度。本文以甘肃省天祝县抓喜秀龙乡高原鼢鼠（Eospalax baileyi）分布区为调查区域，利用RTK技术实现了高原鼢鼠土丘数量和分布情况调查，并结合ArcGIS软件实现了土丘数量及其相对种群密度变化的统计分析。RTK技术在研究其土丘空间分布特征、相对种群密度（以土丘数量代表）以及草地危害评估等方面具有很好的效果。此方法不仅可用于地下啮齿动物土丘数量和分布调查，还可用于地上啮齿动物洞口数量和分布的调查。 |

| Number changes and distribution ranges of mounds made by subterranean rodent is the key to monitor the population size change for this group rodent. Traditionally, people counted the number of mounds and plotted a map to figure out their distribution ranges. Both of the methods had some problem in term of heavy workload and the results were far from perfect. In this paper we used a method named the real-time kinematic (RTK) which based on GPS to estimate the number and range of mounds by subterranean rodent and got a high precision result that can locate a point of the mounds in a precision in the centimeter level. We selected the study area in an area located in the Plateau Zokor (Eospalax baileyi) located in Zhuaxixiulong Township in Tianzhu County, Gansu province in where the subterranean rodent was founded. We used RTK technology to investigate the number and distribution of the mounds by Zokors. We combined ArcGIS software to analyze the changes of the mounds number and its relative population density. According to the more precision results, we believed this method is a good way to study the distribution pattern of Zokor′s mounds and the relative population density of Zokor′s, as well as damage assessment of rangeland caused by the Zokor. We suggested this method can be both used for investigating mounds number and its distribution range of subterranean rodent, as well as used in the investigation of hole made by the aboveground rodents. |
