生态系统服务流研究为量化和映射森林生态系统服务供应和需求的关系及其空间景观模式提供了新视角。森林生态系统服务供应考察的是森林生态系统的状态及供应能力,涉及复杂的生物物理和生物化学变化;森林生态系统服务需求的量化则需要从受益者的空间分布及其行为方式等方面开展监测。文章以林浆纸一体化为例,对森林生态系统所产生的碳流和水流及其供需状况进行了分析。结果表明,基于服务流视角为森林生态系统服务的形态、功能和价值上转化过程领域的进一步深入研究提供了新思路,同时也为森林生态系统可持续管理在理论、方法和政策制定上带来了新挑战。
Ecosystem service flow research provides a new perspective for quantifying and mapping the relationship and spatial landscape patterns of supply and demand of forest ecosystem services. Forest Ecosystem Services Supply covers the state and availability of forest ecosystems and involves complex biophysical and biochemical changes. The quantification of forest ecosystem services needs to be monitored from the perspective of the spatial distribution of beneficiaries and their behavior patterns . Taking the integration of forestry, pulp and paper as an example, the paper analyzes the carbon and water flow produced by forest ecosystems and their supply and demand. The results show that this paper provides new ideas for further research on the form, function and value conversion process of forest ecosystem services based on the view of service flow, and brings about the theoretical, methodological and policy-making of sustainable management of forest ecosystems New challenge
