森林多目标经营单元的时空尺度扩展

Analysis of spatial and temporal scales expansion of forest multi-objective management

森林多目标经营是我国林业发展的重要趋势,而森林本身的特性以及国内外的众多研究证明,森林多目标经营需要考虑多个时空尺度,以满足其生态、经济和社会效益的综合发挥。在界定多功能林业和森林多目标经营的概念及基础上,系统地分析了传统森林经营时空尺度和现代森林多目标经营时空尺度的联系与区别,提出现代森林多目标经营单元空间尺度上应该满足区域、景观和林分多尺度的需要,而在时间尺度上则要综合考虑短期、中期和长期,并以露水河林业局为例给出具体的研究思路,以期为我国开展森林多目标经营提供借鉴。

Multi-objective management is an important trend in China＇s forestry development. This management policy is based on the characteristics of the forest itself and on management objectives. Numerous studies have shown that forest multi-objective management needs to include a multiplicity of spatial dimensions and temporal scales in order to meet the overall ecological, economic, and social benefits. Various factors need to be considered, e.g., the definition of multi-purpose forestry, the concept of forest multi-objective management, and the links and differences between traditional and modern forest multi-objective management in spatial dimensions and time scales. The spatial dimensions of modern multi-objective forest management need to take into account a range of regional, landscape, and stand factors, while the time scale needs to contain short, medium, and long-term objectives. Presently, Lushuihe Forestry is examining specific research ideas to achieve robust multi-objective forest management in China.
