生态系统产品与服务功能是人类生存与发展的基础。生态系统生产总值（GEP）可以定义为生态系统为人类福祉和经济社会可持续发展提供的产品与服务价值的总和，包括生产系统产品价值、生态调节服务价值和生态文化服务价值。生态系统生产总值核算的基本任务有3个，即核算生态系统产品与服务的功能量、确定生态系统产品与服务的价格、核算生态系统产品与服务的价值量。生态系统生产总值核算可以用于揭示生态系统为经济社会发展和人类福祉的贡献，分析区域之间的生态关联，评估生态保护成效和效益。以贵州省为例，探讨了生态系统生产总值核算的应用方法，评价了贵州省生态系统为贵州和其他地区人们福祉和支撑经济社会发展所提供的产品和服务及其经济价值总和。评价结果显示，贵州省2010年全省生态系统生产总价值为20013.46亿元，人均GEP 57526元，是当年该省国民生产总值和人均GDP的4.3倍。研究表明，生态系统生产总值的核算可以反映生态系统对经济社会发展的支撑作用，并为建立生态系统保护效益与成效的考核机制提供基础。;Ecosystem products and services are essentials for human survival and development. Gross ecosystem product (GEP) is defined as total values of ecosystem products and services for human welfare and sustainable development. GEP mainly refers to the total value of direct and indirect use values of ecosystem goods and services, including ecosystem provision value, ecological…

通过收集、整合国内相关数据,推算了符合中国目前情况的各种氮肥、磷肥和钾肥的制造过程中的温室气体排放系数(从原料到工厂大门)。结果显示,我国平均水平的氮肥制造碳排放系数为:合成氨(液氨)1.672 t CE/t N,尿素2.041 t CE/t N,碳铵1.928 t CE/t N,硝酸铵4.202 t CE/t N,氯化铵2.220 t CE/t N,氮肥综合系数为2.116 t CE/t N。我国一般水平的磷肥制造碳排放系数为:重钙0.467 t CE/t P<sub>2</sub>O<sub>5</sub>,磷酸二铵1.109 t CE/t P<sub>2</sub>O<sub>5</sub>,磷酸一铵0.740 t CE/t P<sub>2</sub>O<sub>5</sub>,普钙0.195 t CE/t P<sub>2</sub>O<sub>5</sub>,钙镁磷肥2.105 t CE/t P<sub>2</sub>O<sub>5</sub>,磷肥综合系数为0.636 t CE/t P<sub>2</sub>O<sub>5</sub>。我国先进水平的钾肥制造碳排放系数为:氯化钾0.168 t CE/t K<sub>2</sub>O,硫酸钾0.409 t CE/t K<sub>2</sub>O(其中罗钾法硫酸钾0.443 t CE/t K<sub>2</sub>O、曼海姆法硫酸钾0.375 t CE/t K<sub>2</sub>O),钾肥综合系数为0.180 t CE/t K<sub>2</sub>O。我国大部分氮磷钾肥的温室气体排放系数普遍为欧美平均水平的2倍左右,因此利用国外系数来估算我国的农业温室气体排放量将严重低估化肥施用的影响。
