| 摘要: |
| 【目的】构建基于土地生产能力的河道生态基流保障补偿标准修正模型。【方法】以缺水地区典型河流：渭河干流宝鸡段为例，以农户管理的土地生产能力与研究区平均土地生产能力的比值为修正系数，基于改进生产函数法建立了河道生态基流保障的生态补偿标准修正模型。【结果】极枯水年河道生态基流保障的宝鸡峡塬上灌区补偿标准为3 502.09元/hm2，且补偿标准随保障目标的提升而增加；不同典型年的修正补偿标准存在差异。补偿标准修正模型基本合理可行，不同典型年修正补偿标准与单位面积粮食产量之间存在非线性指数函数关系，灌区各县和受损农户的河道生态基流保障修正生态补偿标准与径流变化呈负相关。【结论】基于土地生产能力的河道生态基流保障补偿标准修正模型可为河道生态基流保障的生态补偿机制构建提供理论基础和技术支撑。 |

| Abstract: |
| 【Objective】The implementation of ecological compensation for the protection of river ecological base flow often faces challenges due to inconsistent management practices. Variations in land production capacity across large irrigation areas, along with concerns from affected farmers about the fairness of a uniform ecological compensation standard, are key issues. This study aims to address these challenges. 【Method】 Grain yield per unit area was used as a key indicator of land production capacity, which was used to develop a corrected model for ecological compensation standards aimed at protecting river ecological base flow. The model was applied to the Baoji section of the Weihe River basin as a case study to demonstrate the corrected ecological compensation model. 【Result】The key findings are as follows: ① The revised model is rational and feasible based on the analysis. ② The ecological compensation standard for protecting the river’s ecological base flow is 234.64 yuan/mu. ③ A quantitative relationship between grain yield per unit area and the modified ecological compensation standard for affected farmers was established. ④ The advantages and limitations of the modified compensation model are discussed.【Conclusion】This study provides a theoretical foundation and technical support for refining ecological compensation standards for the protection of river ecological base flows, especially in water-scarce regions of Northwest China. |
