在景观尺度,德国的GISCAME把权属、经营措施等森林经理学方法对森林功能与服务的影响加入到森林多目标规划中,对多权属区域森林多目标权衡分析具有重要意义。以生物量规划为例,该平台引入一种提高生物量和生态服务价值在时间和空间上动态权衡的土地利用策略模型,通过生长与收获模型结合的评估方法,解决了小班经营决策和区域规划目标不统一的问题,用情景分析来检验不同措施选择在应对气候变化和生物量增加要求上的差异。从森林经营管理的角度来看,该系统在生长与收获模型、森林调查数据、权属转换率、可及性、保护等级、皆伐或者间伐经营措施改变等方面还存在不确定性假设问题。为将GISCAME平台引进到我国森林经营管理中还需要加强嵌套精准模拟和景观资源可及性等问题研究,系统探索森林权属功能潜力及森林保护等级功能潜力数量差异,为森林景观精准规划与经营管理提供科学参考。
At the landscape scale, GISCAME in Germany adds the influence of forest managers and management methods on forest function and service into forest multi-objective planning, which is of great significance to the multi-objective trade-off analysis of forest in multi-tenure area. Taking biomass planning as an example, the platform introduces a land use strategy model that improves the dynamic balance between biomass and ecological service value in time and space. Through the combination of growth and harvest model, this platform solves the problem of small-scale management decision and regional planning The goal is not uniform, and scenario analysis is used to test the differences in the response of different measures to climate change and biomass increase. From the perspective of forest management and management, the system still has uncertain assumptions about growth and harvest models, forest survey data, rate of ownership conversion, accessibility, level of protection, changes in clear-cut or thinning management practices. In order to introduce the GISCAME platform into forest management in our country, we also need to strengthen the research on such issues as precision nested simulation and accessibility of landscape resources. We systematically explore the functional potential of forest ownership and the differences in functional potential of forest protection levels, Management provide scientific reference.
