摘　　要：对昆明呼马山昭觉林蛙可利用食物资源研究表明:环境中可利用食物资源以节肢动物门昆虫纲和蛛形纲动物为主,其中昆虫纲主要由双翅目、直翅目、鞘翅目、同翅目、半翅目、膜翅目和鳞翅目等组成。可利用食物资源组成和数量都有着明显的季节变化。影响可利用食物资源季节变化的主要因素是气候。选择种类丰富和满足其生理需求适宜性较大的食物是昭觉林蛙利用资源的两种方式。According to the study of Rana chaochiaoensis in Humashan of Kunming, it showed that available food resources of the environment included Insecta and Arachnoidea of Arthropoda as the major elements, of which Insecta mainly contained Diptera, Orthoptera, Coleoptera, Homoptera, Hemiptera, Hymenoptera, Lepidoptera and etc. The composition and quantity of available food resource had obvious seasonal changes. The main factor affected the seasonal changes of available food resources was the climate. Selecting rich kinds of food and greater adaptation were the two ways of Rana chaochiaoensis to satisfy their physiological requirements by using food resources.
