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。
Quantifying and mapping supplies and demands of ecosystem services is essential for the sustainable man- agement of forest ecosystem. Ecosystems' status and capacities need to be monitored to quantify the supplies using complex biophysical and biochemical models. And the demands-side requires the distributions and behaviors of beneficiaries in spatial patterns. Considering the forestry pulp paper integration of enterprises, the paper examined the carbon flows and water flows. We argue that the ecosystem services flows provides a new solution to the research of transformation process of form, function and value of forest ecosystem services. Meanwhile, new challeng- es in theories, methods and policies for the sustainable management of forest ecosystem have been brought forward.
