Biomass distribution patterns of ecotones between forest and swamp in Changbai Mountain

摘要

This paper studied the biomass distribution patterns of Larix olgensis/swamp ecotones and Betula platyphlla/swamp ecotones in Changbai Mountain so as to provide theory foundation for the manage- Ment of these nature resources, by setting up sample belts, investigating initial data along the environmental Gradients change, and establishing regression models. By means of regression models, the biomass of Communities, layers, tree species and organs was calculated. In this system, it was found that the community Biomass increased gradually along the environmental gradients change from swamp to forest in Changbai Mountain. Furthermore, the ecotoneal biomass distributed mainly over tree layer. The tree biomass distrib- Uted mainly in two or three dominate tree species.
