摘　　要：通过调查科尔沁沙地南缘的流动沙地、半流动沙地、固定沙地、林地4种立地类型的植被种类、数量、盖度、丰富度、生物量等因素,分析了其不同立地类型的植被分布特征。结果表明:4种立地类型所分布的植被种类数量相仿,其中固定沙地较单一,林下种类相对丰富;就物种多样性而言,固定沙地多样性略低;植被生物量差距较大,最大的是固定沙地,最小的是流动沙地;有机质的积累则是林内较高。By investigating the types,quantity,coverage,richness,biomass and other data of four kinds of site types of mobile sandy land,semi-floating sandy land,fixed sandy land and under forest on the southern margin of Horqin sandy land.Among the four sites,the number of species is similar,of which the fixed sandy land is relatively single and the species under the forest is relatively abundant;in terms of species diversity,the diversity of fixed sandy land is slightly lower;the difference of vegetation biomass is larger,the largest is the fixed sandy land,the smallest is mobile sandy land;the accumulation of organic matter is higher in the forest.
