2008-2016 Water security status and short plate element screening in Shandong province

Abstract

Abstract In order to explore the applicability of the methods for protecting regional water resources, the water resources safety evaluation index system of Shandong Province was constructed, and the water resources safety relative closeness degree was used to characterize the water resources security situation of Shandong Province from 2008 to 2016; the matrix of water resources safety impact factors of Shandong Province was constructed. The factor analysis method is used to calculate three principal component factors, and the short board elements are identified. The paper concluded by comparing the development trend of water resources security in Shandong from the aspects of vertical (interannual) and horizontal (indicator). The results show that: (1) The water security system of Shandong Province was mildly unsafe in 2009. It was barely safe in 2015 and 2016, and the rest of the year was in an unsafe state. In 2008-2016, the state of water resources security in Shandong Province showed that the situation in the previous period was relatively tight and the later contradictions eased, but the overall security situation was still severe. (2) Factor analysis shows that the lack of water resources and high-intensity development and utilization are the main short-term factors affecting water resources security in Shandong Province.
