摘要
运用包含非期望产出的SBM模型测度 2011-2020 年西北干旱区 34 个地级市的水资源绿色效率,利用自然断点法探究西北干旱区水资源绿色效率的时空演变特征,并在此基础上分析西北干旱区各地级市的节水减排潜力.结果表明:2011-2020 年西北干旱区34 个地级市有88.2%的市水资源绿色效率未达到生产前沿面;水资源绿色效率总体呈现出南部、中部、北部逐渐递增的空间分布态势;城市之间的节水减排潜力差异显著,区域之间呈现"中部＞南部＞北部"的发展格局;从节水减排技术、产业结构、水资源管理等角度提出相关对策建议,以期推动西北干旱区各城市水资源绿色效率的提升.
Abstract
The undesirable output SBM model was used to measure the green efficiency of water resources in 34 cities of the northwest arid region from 2011 to 2020,using natural breakpoint method to explore the spatial and temporal evolution of the green efficiency of water re-sources in northwest arid region,on this basis,and the potential of water saving and emission reduction of each city was analyzed.The results show that from 2011 to 2020,88.2%of the 34 cities in the northwest arid region do not achieve the green efficiency of water resources at the forefront of production.The green efficiency of water resources generally presents the decreasing spatial distribution trend in the southern,central and northern regions.The potential of water saving and emission reduction between cities is significantly different,and the develop-ment pattern of"central＞southern＞north"is present between regions.Relevant countermeasures and suggestions are put forward from the per-spectives of water saving and emission reduction technology,industrial structure and water resources management for promoting the improve-ment of green efficiency of water resources in the northwest arid region.
