基于DPSIR模型的中部地区水生态环境指标体系构建及评价

Construction and Evaluation of Water Ecological Environment Index System in Central China Based on DPSIR Model

基于DPSIR模型,建立中部地区水生态环境质量评价指标体系,利用客观赋权熵值法确定指标权重,定量分析2010—2019年中部地区水生态环境状况。结果表明:中部地区及其六省的水生态环境质量总体呈现发展向好的趋势,但缺乏稳定性,2010—2019年水生态环境质量都经历了一定的波动,尤其是“十三五”规划提出后虽然整体都有较好的发展趋势,但个别省份仍然有波动起伏现象。最后,针对中部地区水生态环境中所存在的问题,提出促进水生态环境可持续发展的措施。

Based on DPSIR model, the evaluation index system of water ecological environment quality in Central China is established, the index weight is determined by objective weighting entropy method, and the water ecological environment in Central China from 2010 to 2019 is quantitatively analyzed. The conclusion shows that the water ecological environment quality of the central region and its six provinces generally shows a good trend of development, but lacks stability. The water ecological environment quality has experienced certain fluctuations from 2010 to 2019. Especially after the 13th five-year plan is put forward, although there is a good development trend as a whole, some provinces still have fluctuations. Finally, in view of the problems existing in the water ecological environment in the central region, the measures to promote the sustainable development of water ecological environment are put forward.
