Abstract

The Dahurian larch, Larix gmelinii (Rupr.) Rupr., forests with different origins (natural forests,man-made forests and burned forests) in A’ershan area were divided into six resource gradients using Resource Gradient Index (RGI). The index is composed by stand age (AG), stand altitude (AL), and species individual (SI). After community investigation, the niche breadth (B(sw)i and B(L)i), niche overlap (Lih and Lhi) and niche similarity of dominant understory populations (Cih) were derived by quantitative analysis. The sum of importance values of Carex chinganensis Litw. and Lolium perenne L. were the highest, 114.924 8% and 70.911 1%, respectively. Geranium dahuricum DC.,Galium boreale L.,C. chinganensis Litw. and L. perenne L. had the largest niche breadth. These species had high adaptability, broad habitats, and inclined to be generalist species. The studies showed that the populations with larger niche breadth had relatively larger niche overlap and similarity in resource utilization. However,some species such as Artemisia sacrorum Ledeb., Potentilla chrysantha Trev. and Rumex patientia L. had smaller importance value and niche breadth, but relatively higher niche overlap and similarity. Therefore, niche breadth is not the only determinant of niche overlap and similarity. In addition, both the competition in sharing resources and the mutual promotion in utilizing resources of two populations could be reflected by the niche overlap. The species with large niche breadth can function as the pioneer species in artificial vegetation recovery, while the species with high niche overlap can function as accompanying species to fully utilize environmental resources, so that the forest vegetation that had been damaged could be gradually recovered.
