摘要/Abstract

摘要： 以TEM和DNDC模型为例,在分析国外生物地球化学模型发展基础上,按照模拟方法、应用目的、元素类型、生态系统类型和空间尺度等对现有的生物地球化学模型进行了分类.对生物地球化学模型的基本框架(植物、大气和土壤3个组分及植物大气、植物土壤和土壤大气界面等3个界面),以及内部基本过程(物理的、化学的和生物的过程)进行了总结分析.对目前生物地球化学模型建立中的几个问题(如跨尺度问题、与地理信息系统(GIS)和遥感技术结合、考虑人类活动的影响和生物地球化学模型的比较研究)的研究动态进行了评价.

Abstract: Biogeochemical modeling plays a role as important as experimental measurement in ecosystem research. This paper analyzed the development of biogeochemical model using TEM and DNDC model as cases. Current biogeochemical models were classified according to modeling method, application purpose,element concerned, ecosystem type,and spatial scale. The basic framework (three component:plant,air and soil,and three interface:plant-air,plant-soil,and soil-air) and interior fundamental processes (physical,chemical and biological processes) of biogeochemical models were reviewed,and some important problems concerning biogeochemical modeling,such as scale upping,integrating GISand remote sensing,involved human activity,and comparison study were focused.

Key words: Biogeochemistry, Model, Terrestrial ecosystem, long-term enclosure, phospholipid fatty acid, soil microorganisms, free grazing, carbon metabolism
