摘　　要：2006年6月～2009年10月,采用直接观察法和样带样方法在四川省雅江县帕姆岭对四川雉鹑夏秋季的植物性食物及其资源分布状况进行了调查。四川雉鹑采食的植物种类有34种,其中草本植物32种,木本植物2种。在夏季取食的种类有28种,秋季18种,两个季节同时取食的植物种类有12种。四川雉鹑取食强度高的物种有15种,中度的有11种,低度的有8种。夏季四川雉鹑主要取食草本植物的叶与根茎,秋季主要采食的是成熟的种子和果实。在不同生境类型中四川雉鹑的食物组成与丰富度存在差异,光亮杜鹃灌丛和高山杂草类草甸生境的食物种类和食物总量都相对较高,是四川雉鹑的食物基地,而鳞皮冷杉-川滇杜鹃林和高山松林的食物种类和数量相对较低。By direct sighting and quadrat sampling, the diets of buff-throated partridges Tetraophasis szechenyii and the distribution of plant-food resources were studied at Pamuling in Yajiang county of Sichuan province from June 2006 to October 2009. The results showed that partridges fed on 32 herb species and 2 shrub species （28 in summer and 18 in autumn, with 12 in both the two seasons）, of which 15 were the highest eaten and 8 were the least eaten. In summer, partridges mainly fed on leaves, roots and stems of herbs, and in winter they switched to fruits and seeds. The distribution of food resources varied in different habitat types. The diet plants were relatively abundant in azalea shrubs and alpine meadows which were the main foraging habitats of the partridges, in comparison with those in flaky fir and alpine pine forests.
