摘要
稻田生态系统服务以及其多功能性价值对地球生命支持系统的功能有着极其重要的作用。我们估算了近30年（1980-2014）来中国稻田生态系统服务价值（ESV）。结果表明，在此期间中国稻田生态系统服务价值总量呈现波动上升趋势。其中，固碳价值所占比重最高，其次是控温和温室气体价值。不同稻区稻田生态服务价值强度存在显著差异。南方水旱轮作区和双季稻区的单位产量生态服务价值强度相近，均显著高于东北一季稻区和西南稻区。近30年（1980-2014）来，除广西、浙江、福建、广东四省（自治区）外，其他省份生态服务价值总量均有不同程度增加。这些结果表明，我国稻田生态服务价值的总量、结构和强度存在显著的时空差异性，相关研究可进一步指导适合我国水稻绿色生产技术的开发和应用。
Abstract The ecological systems services or multi-functionality of paddy rice cultivation are critical to the functioning of the Earth’s life-support system. We estimated the ecosystem services value (ESV) of paddy rice during 1980–2014 across China. The results indicated that the ESV of the paddy field in China showed an upward trend during this period. The share of ESV on CO2 sequestration was the highest, followed by ESV on temperature cooling and greenhouse gas (GHG) emission. The yield-scaled ESVs of Zones II (southern rice–upland crops rotation regions) and III (southern double rice production regions) were similar and significantly higher than the ESVs of Zones I (northeastern single rice production regions) and IV (Southwest rice–upland crops rotation regions). Between 1980 and 2014, the ESV of each region increased to varying degrees, except for the ESVs of Guangxi, Zhejiang, Fujian, and Guangdong. Such effects suggest the existence of a significant spatial–temporal variation in the total amount, structure, and density of ESV of paddy fields in China, which can further guide the development of future options for the adaptation of healthy rice production in China.
