Abstract：
A stable and complete agricultural horizontal ecological compensation (AHEC) is an essential means of reconciling agricultural ecosystem protection and regional development and is also the key to the sustainable use of agricultural water and land resources. Unlike previous methods of studying agricultural ecological compensation (AEC), this study analysed the direction and amount of net transfer of agricultural land and water use along with inter-provincial trade. In conjunction with the value of ecosystem services embedded in agricultural land and water resources, this study calculated AHEC standards and estimated payments/reimbursements from each province. We found that agricultural land and water resources continued to flow from the underdeveloped inland provinces to the developed coastal provinces in 2017. In addition, the value of agricultural ecosystem in the central and coastal areas can be further enhanced by reducing the negative value of their cropland. Even though the ecological compensation standards for virtual agricultural water use (AWU) was much lower than the ecological compensation standards for virtual agricultural land use (ALU), the integrated AHEC in 31 provinces was more reasonable than considering only virtual ALU and virtual AWU. These findings are of great theoretical and application significance for the government to establish a systematic and feasible framework for inter-provincial AHEC and serve as a reference for other countries to conduct related research.
摘要：
一个稳定完整的农业水平生态补偿(AHEC)是协调农业生态系统保护和区域发展的重要手段,也是农业水资源和土地资源可持续利用的关键。与以前研究农业生态补偿(AEC)的方法不同，这项研究分析了农业土地和水资源净转移以及省际贸易的方向和数量。结合农业土地和水资源中嵌入的生态系统服务的价值，这项研究计算了AHEC标准和每个省份的估计付款/报销额.我们发现，2017年农业土地和水资源继续从欠发达的内陆省份流向沿海发达省份。此外,通过减少耕地的负值，可以进一步提高中部和沿海地区农业生态系统的价值。尽管虚拟农业用水的生态补偿标准(AWU)远低于虚拟农业土地利用的生态补偿标准(ALU),31个省的综合AHEC比仅考虑虚拟ALU和虚拟AWU更为合理。这些研究结果对于政府建立系统、可行的跨省AHEC框架具有重要的理论和应用意义,也为其他国家开展相关研究提供参考。
