黄河流域经济带生态环境绩效评估及其提升路径

黄河流域经济带是我国北方重要的经济走廊,科学评估黄河流域经济带生态环境绩效水平,提高黄河流域沿线9省生态环境质量是实现黄河流域经济带的高质量发展重要举措之一。运用生态环境质量评估、生态效率评估等研究方法,开展2012—2017年的生态环境质量、生态效率和绿色全要素生产率评估。结果表明:黄河流域经济带生态环境绩效水平总体呈现由较低水平不断提升的趋势;黄河沿线九省在生态环境质量和生态效率系统层中有明显差异,生态环境质量系统层中,上游地区的最优;生态效率系统层中,中下游地区的生态效率最优且稳定。研究结果从生态系统修复功能、产业绿色发展和完善生态环境顶层制度设计3个方面提出加快推进黄河战略的实施,提升黄河流域经济带生态环境绩效。

Ecological Environment Performance Assessment and Improvement Path of the Yellow River Basin Economic Belt

The Yellow River Basin Economic Belt is an important economic corridor in the north of China. Scientific assessment of the performance level of the ecological environment of the Yellow River Basin Economic belt and improvement of the ecological and environmental quality of the nine provinces along the Yellow River Basin were one of the important measures to achieve the high-quality development of the Yellow River Basin economic belt. In this paper, ecological environment quality assessment, ecological efficiency assessment and other research methods were used to evaluate the assessment of ecological environment quality, ecological efficiency and green total factor productivity from 2012 to 2017. The results showed that the ecological environment performance level of the Yellow River Basin economic belt presented a trend of increasing from a low level. The nine provinces along the Yellow River had obvious differences in eco-environmental quality and eco-efficiency system layer, and the upstream region was the best. In the ecological efficiency system layer, the ecological efficiency in the middle and lower reaches was the best and stable. The research results proposed to accelerate the implementation of the Yellow River Strategy from the three aspects of ecosystem restoration function, industrial green development and the improvement of the top-level system design of ecological environment, so as to improve the ecological and environmental performance of the Yellow River Basin economic belt.
