摘要
陆地生态系统物质交换模型是生态系统水、碳、养分循环研究的重要方向和极具发展前景的不可替代的手段。本文对近年来发展的众多陆地生态系统物质交换模型进行了归类:1)根据建模思路不同分为经验模型、过程模型和混合模型;2)根据物质传输机制的不同分为生物物理模型和生物地球化学模型;3)根据对植被结构处理方式的不同分为单层模型、双层模型和多层模型;4)根据模型应用性不同分为诊断性模型和预测性模型;5)根据构建模型的逻辑结构不同分为自下而上模型和由上而下模型;6)根据研究尺度的不同分为生态系统尺度模型、景观尺度模型和区域尺度模型;7)根据植物生理过程的不同分为光合作用模型和蒸腾作用模型。最后对不同类型模型的优缺点进行综合分析,探讨了新的发展方向。
