摘要
通过对海北生态系统定位站附近3种植物播娘蒿Descurainia sophia、荠菜Capsella bursa-pastoris、灰绿藜Chenopodium glaucum的分布情况的调查,初步分析了3种植物的扩散策略,并预测了其对高寒草甸生态系统潜在的影响。
The distribution of Descurainia Sophia, Capsella bursa-pastoris and Chenopodium glaucum around Haibei alpine meadow ecosystem station were investigated. The diffusion strategy of the three plants was analyzed and their potential effects on alpine meadow ecosystem were predicted.
