摘　　要：通过对浑善达克沙地实验地4种立地类型柠条播种苗的实际跟踪调查,初步摸清了柠条在该区域的生长表现情况。调查结果表明:4种立地类型下按生长状况由好到次的顺序排列是,流动沙丘>半固定沙丘>风蚀沟>丘间低地,物种间的竞争是影响当年生柠条播种苗生长好坏的最主要原因。Based on investigating the sown seedling of Caragana korshinskii in four kinds of site type in Hunshandake Sandy Land, the growth situations of Caragana korshinskii in this area have been felt out preliminarily. The resuhs show that the order of growth in four kinds of site type is moving sand dune 〉 semi - fixed dune 〉 wind gully 〉 low land between hills. The main factor influencing the growth of one - year sown seedlings of Caragana korshinskii is the interspecific competition.
