摘要: 通过对科尔沁沙地几种主要生境类型,固定沙丘、半固定沙丘、农田和沙质草甸蛴螬群落的组成和动态研究。结果表明:几种生境蛴螬群落优势种均为东方绢金龟和黄褐异丽金龟,常见种相互间有明显差别。几种生境蛴螬群落的密度、频度和种类数的大小排序为农田>固定沙地>半固定沙地,沙质草甸蛴螬群落有较高的密度和频度,但种类数相对较少。由于特殊的地理环境和气候条件,科尔沁沙地蛴螬群落季节动态呈夏季密度较高、春秋季密度较低,但年度间明显不同。而且,对于缺少人为管理的固定沙地和半固定沙地,降水成为制约蛴螬群落发生的主要因素。

关键词: 科尔沁沙地, 蛴螬群落, 季节动态

Abstract: In Horqin sandy land, the dominant species are Anomala exoleta Faldermann and Serica orientalis Motschulsky. But the communities of Scaraeoridea Larvea are different in fixed sand land, semi-fixed sand land, farm land and sandy meadow. This means they have different common species. As for density, frequency and the number of Scaraeoridea Larvea, the order is farmland > fixed sand land > semi-fixed sand land. In sandy meadow, the density and frequency of Scaraeoridea Larvea are higher than that of in other inhabits. But the number of species is lower. Because the condition of weather and environment, the densities of Scaraeoridea Larvea are higher in summer than that of in spring and autumn. But the dynamic feature is different between years. In semi-fixed sand land and fixed sand land, because of the poverty of the soil and plant, the rainfall is the key factor for Scaraeoridea Larvea growth.

Key words: Horqin sandy land, community of Scaraeoridea Larvea, seasonal dynamic
