Abstract:

On the base of building different levels of forest ecological niche measurement indicators of Yichun forest, we calculate the different grades of forest ecological niches coefficient, in accordance with the cold temperate coniferous forests, temperate deciduous broad-leaved forest, coniferous and broad-leaved mixed forest, we assess the yearly value of water conservation, fix CO2 and release O2, the soil conservation, recycling nutrients and nutrient store, atmosphere environmental purification, bio-diversity protection, landscape resources, and so on, and make the assessment results more reasonable, in order to provide a reference for the formulation of sustainable development policies of Yichun forest aim at providing a reference for sustainable development policy formulation of Yichun forest, which would be of great significance to the protection and utilization of forest resources in this region.

Key words: ecological niche, Yichun forest region, ecological service function of forest, capitals assessment
