Niche characteristics of plant populations in evergreen broad-leaved forest in Shiyang forestry centre
Niche breadths and overlaps of 16 main tree populations and 23 main shrub populations in evergreen broad-leaved forest in Shiyang forestry centre of Zhejiang Province were measured using the formulas described by Shnnow-wiener, Levins and pianka.

| Summary: | Niche breadths and overlaps of 16 main tree populations and 23 main shrub populations in evergreen broad-leaved forest in Shiyang forestry centre of Zhejiang Province were measured using the formulas described by Shnnow-wiener, Levins and pianka. The niche similarities of 16 main tree populations were measured using the formulas described by Schoener. The relationships among niche breadth, niche similarity and niche overlap were discussed. The results showed that the niche breadths of main dominant species were greater. The Shnnow-wiener and Levins's niche breadths of Schima superba, Cyclobalanopsis glauca, Rhododendron ovatum and Rhododendron latoucheae, the main dominant species in tree layer, were 0.925, 0.908, 0.840, 0.814 and 0.799, 0.748, 0.578, 0.574 respectively, and those of Itea chinensis var. oblonga, Rhododendron ovatum, Camellia cuspidata and Eurya rubiginosa var. attenuata, the main dominant species in shrub layer, were 0.946,0.913,0.855, 0.868 and 0.794, 0.745,0.663,0.650 respectively. The niche similarities of the main dominant species in tree layer were smaller, so the community sustains stability for a long time. The niche overlaps among the species with the same or similar environment requirements and with high niche similarities were greater, while those between the species with broad niche breadth and other species were much greater. |
