| 摘 要： | 本文依据实地观测资料，探讨了古尔班通古特沙漠南缘区脊椎动物群落各摄食集团的动种构成及其随物候期食物资料变化所产生的相应分化和转换，揭示出该区域脊椎动物食集团具有不稳定的特征，分析得出，少数生态适应性强的物种摄食量集团的分化是维系沙质荒漠生态系统完整性的重要生态过程，它介研究脊椎动物群落营养结构动态的关键摄食集团。

| Abstract: | Based on field observation data, this paPer discusses sPecies comPoSition, feeding guild and its shift of sandy desert vertebrate community, reveals some unstable characters of these guilds due to bo resource change. The results show that altemation an4 shift of few species feed strategies among feed ing guilds, which ones have higher population density,are of important ecological role in maitaining desert ecosystem completeness, these species should be critical ones to study trophic structure, energy and talter flow through the vertebrate community. |
