基于生态区位测度的伊春林区森林生态服务功能价值评估

Ecological Service Function Value Assessment of Yichun Forest Based on Ecological Niches Measurement

在构建伊春林区森林生态区位测度指标体系的基础上,测度不同等级森林的生态区位系数,按照寒温带针叶林、温带落叶阔叶林、温带红松阔叶混交林等不同林分,对伊春林区森林的涵养水源、固定CO2和释放O2、保育土壤、营养物质循环和储藏、净化大气环境、生物多样性保护等6种生态服务功能形式的价值进行评估,使得评估结果更加合理。本文可为伊春林区森林可持续发展政策的制定提供参考依据,同时对该区域森林资源保护和开发利用具有重要的意义。

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.
