《京都议定书》的目标是减少6%的二氧化碳排放量，要求采用清洁的生物质能技术来替代化石燃料。在日本发现的大稻田作为CO2固定和生物质能源。这些稻田也是甲烷的来源，甲烷的温室效应是二氧化碳的21倍。作者开发了一种基于光合作用型粮食生产模型的监测方法，利用气象数据和归一化植被指数NDVI。本研究估算了日本10个稻田的固定量。根据累积的季节性光合固定CO2计算出的平均值为3，950 gCO 2/m2/yr。根据平均收获指数HI=0.45估计，日本全国稻田的CO2固定量为31.32 Mt CO2/年。利用1993 - 2000年水稻平均产量中的碳权重，对水稻、秸秆和植物根生物量中固定CO2的划分进行了评估和验证
The Kyoto Protocol aims for a 6% of reduction in CO2 emission, requiring clean and biomass energy technology instead of fossil fuels. The large paddy fields found in Japan act as a CO2 fixation and a biomass energy source. These paddy fields are also sources of CH4, which has 21 times the greenhouse effect of CO2. The author has developed a monitoring method based on a photosynthesis type of grain production model using meteorological data and the Normalized Difference Vegetation Index NDVI. The present research estimated the amount of fixation by ten paddy fields in Japan. An average value of 3, 950 gCO2/m2/yr was calculated, based on the accumulated seasonal photosynthetic fixation of CO2. The amount of CO2 fixation of 31.32 Mt CO2/yr by paddy fields in whole Japan was estimated from the average harvest index HI=0.45. The division of fixed CO2 into rice, straw and root portions of plant biomass was evaluated and validated by a carbon weight included in average rice production from 1993 to 2000
