浙江省农业系统碳源、碳汇现状评估分析

摘要

Based on the evaluation framework of carbon ( C ) source and sink of the agricultural system, the annual C source and sink from the agricultural system in Zhejiang Province during the period from 2000 - 2009 has been estimated. The results showed that agricultural system in Zhejiang Province totally showed an obvious C increase trend due to the C sink from forestry and arable land. The increase in the fertilizer production and fossil consumption were the primary carbon emission sources.%通过搭建农业系统碳源、碳汇评估的框架,该文定量分析了2000 ～ 2009年来浙江农业系统碳汇、碳源的主要构成及其变动趋势,研究表明:浙江农业系统总体呈碳增汇趋势,林地、农地是碳吸收的主要构成,而化肥及农用柴油用量的大幅上升是碳排量增加的主要原因.
