基于FVS构建北京地区油松生长仿真框架的研究

在森林经营管理中,往往需要精确预测到未来林分的生长和收获状态,所以对植被仿真系统的研究成为热点。FVS是一套国外较先进的植被仿真系统,但由于FVS系统庞大,设计体系也十分复杂,经过对FVS仔细分析、研究和系统跟踪,发现对模型修改替换极其复杂,不适于本地化的应用。本文基于FVS设计理念和其主流程重构了一套完整的本地化的仿真框架,提供模型接口实现了模型的修改替换。最后选择了北京地区油松作为典型树种,替换了部分模型,利用试验调查数据验证了该框架的完整性和有效性。

Study on FVS-based framework of Pinus tabulaeformis growth simulation

In forest management,accurate prediction of the future state of forest growth and yields is necessary.We choose FVS software as our support tools and study the system of vegetation simulator.Sine FVS is a large system and very complex framework for design,we re-design and choose some modules from a number of modules those adapt to the Beijing area.And then we have also revised and replaced trees model to design and develop a complete set of simulation framework of localization after careful analysis of the FVS,meticulous research of the FVS,and patient tracking the system.Finally,we use the pilot survey data to verify the completeness and effectiveness of the framework.
