摘　　要：水资源生态经济价值是经济价值、社会价值和生态环境价值的统一,分析其价值变化规律对合理优化配置水资源、促进水资源生态经济系统可持续发展具有重要意义。在采用能值分析方法核算郑州市2009~2020年水资源生态经济价值的基础上,对其时间演化规律及影响因素进行探讨,并采用R/S分析法分析了其未来发展趋势。结果表明,郑州市水资源生态经济价值总体呈增长趋势,价值变化主要受GDP、人均可支配收入、污废水排放量等多种因素的影响,其时间序列结果显示未来趋势与过去特征呈正相关关系,即郑州市水资源生态经济价值未来仍呈增长趋势。The ecological and economic value of water resources is the unity of economic value, social value and ecological environmental value. It is of great significance to analyze the change rule of its value for rationally optimizing the allocation of water resources, promoting the sustainable development of the ecological and economic system of water resources. The emergy theory analysis method was used to calculate the ecological and economic value of water resources in Zhengzhou City from 2009 to 2020. Its time evolution law and influencing factors were discussed, and its future development trend was analyzed by R/S analysis method. The results show that there is a growing trend for water ecological economic value in Zhengzhou City on the whole. The value change is mainly affected by GDP, per capita disposable income, sewage wastewater emissions and other factors. The results show that the future trend in the past time series characteristics were positively related, namely, water ecological economic value in Zhengzhou City still showed a trend of growth in the future.
