摘    要:充分发挥森林生态效益是当前森林经营管理工作的重点,森林生长模拟系统是森林经营管理的常用工具。介绍了美国的森林生长混合模拟系统FVS-BGC(FVS-Bio-Geochemical Cycles),该系统是由经验生长收获模型(FVS:Forest vegetation simulator)与林分生物地球化学循环过程模型(STAND-BGC:Stand Bio-Geochemi-cal Cycles)组成的混合模拟系统,可以基于生理过程、气候变化等环境条件来模拟单木和林分两个水平在日和年时间尺度上的生长过程;还介绍了该系统的功能、结构、运行流程以及输入输出结果3个方面,并以一块美国火炬松(Loblolly pine)林分为例进行了模拟预测。

关 键 词:FVS  FVS—BGC  生长模型  过程模型  混合模型  森林经营管理  森林生态系统经营

Abstract:Maximize amplifying the ecological benefit becoming the main point in processing of forest management. Forest growth model was generally used for forest management. In this paper the hybrid forest growth simulation system FVS - BGC developed in America was introduced. FVS - BGC is a hybrid model of process - based model STAND - BGC ( STAND Bio - Geochemical Cycles) and experiential forest growth and yield model FVS (Forest vegetation simulator). FVS - BGC mod- el can projected the daily and yearly growth increments in tree or stand level. Tnis paper introduced this model in four parts: model function and structure, running process, input and output files. An example modeling the growth of Loblolly pine stand was also given in this paper.
Keywords:FVS  FVS-BGC
