Summary: | Abstract
To reasonably evaluate the water resource security state, this research built a water resource security evaluation index system of the Yangtze River Economic Belt (YREB) based on the driving force-pressure-state-impact (DPSI) concept framework, established a water resource security evaluation model by combining the entropy weight method with the fuzzy set pair analysis method and conducted quantitative evaluations of the water resource security states from 2008 to 2016. All the work above was based on the comprehensive consideration of the water resource characteristics in different areas of the YREB, following the index system construction principles. The results have shown that on the whole, the water resource security state of the YREB has generally undergone a process from getting worse to getting better in the latest nine years. From the aspect of the percentages of the water resource security grades, the spatial distribution of water resource security in the YREB is highest in the downstream area, second in the middle reaches, and lowest in the upper reaches. From the aspect of the DPSI security evaluation results, the driving force and state of the water resource are the important factors affecting the water resource security of the YREB. |
