柠条的更新生态位及其与荒漠植被恢复的关系

Regeneration Niche of Caragana spp.and Its Relationship with the Restoration of Desert Vegetation

更新生态位是一个新的成熟植物个体成功地代替另一个成熟个体所要求的可能生态位,其生活史早期阶段的一系列特点可以作为其更新生态位。对蝶形花科(Papilionaceae),锦鸡儿属(Caragana)落叶灌木柠条(Caraganaspp.)的种子萌发、幼苗生长、土壤种子库和营养繁殖等更新生态位特征及其与荒漠植被恢复的关系进行了综述,旨在为柠条的繁殖生物学和恢复生态学研究提供更新生态位方面的理论依据。

The regeneration niche was a possible niche that required by a new mature plant individual to replace another mature individual successfully,and its serious of characteristics of early stage of life history could be used as its regeneration niche.The characters of regeneration niche for seed germination,seedling growth,soil seed bank and vegetative reproduction of Papilionaceae and Caragana spp.and its relationship with restoration of desert vegetation were summarized,for the purpose of providing theoretical basis for regeneration niche in the study on reproductive biology and restoration ecology of C.spp..
