摘要:

针对土地利用碳排放核算方法的参数设置烦琐、计算过程复杂等缺点,限制了碳排放核算模型广泛应用于我国土地利用/覆被变化导致的碳收支研究。本文选择了簿记模型基本原型作为核心算法,构建一套包含土地开垦/退耕、森林收获/恢复4种情景在内的土地利用碳排放核算系统。系统以地理区域为核算基本单元,可逐年并行核算多个区域土地利用活动导致的土壤和植被直接碳排放,提高了碳排放估算的效率;系统界面简洁明了、输入参数少、操作简便。

Abstract:

Due to the tedious parameter setting, complex calculating process and complicated logic structure, the model and method to calculate the carbon emission induced by land use/cover change have been limited to widely apply in the domestic research field of carbon budget estimation. Selecting the fundamental principles of bookkeeping model as the core algorithm, this research has constructed a comprehensive system including four core functions which can effectively estimate the carbon emission induced by land reclamation, abandoned farmland, forest harvest and recover. The comprehensive system can parallelly calculate the directive carbon emission of soil and vegetation disturbing from the human land use in many regions which can be the administrative districts or geographical units. It is improved the effect of system due to the concise interface, few parameters and convenient operation.

Key words: carbon emission, bookkeeping model, land use, estimation system
