基于改进G1-和谐度方程的兰州市水生态文明评价

通过水生态文明理念,对兰州市水生态文明建立相关评价指标体系,以兰州市为例进行水生态文明程度评价研究,从而判断重点问题,进行有效解决。采用熵权、变异系数、G1相结合的改进G1法较为客观地确定兰州市水生态文明评价指标权重,通过和谐度方程(HDE)综合评价方法定量分析兰州市2014-2017年水生态文明程度。兰州市水生态文明建设中应加大对水监管和水文化的管理及宣传,其2014-2017年和谐度值分别为0. 08、0. 38、0. 72、0. 94,水生态文明程度显著提高。兰州市水生态文明程度逐年提高,2017年已达显著文明,通过打造黄河风情线,近年来兰州市水生态建设效果明显,随着发展阶段的不同将伴随着不同侧重点,应需在研究中更加完善指标体系,提出不同时段的相关特点,更好地指导兰州市水生态文明建设工作。

Water ecological civilization evaluation of Lanzhou City based on improved G1-harmony degree equation

Through the concept of water ecological civilization, the relevant evaluation index system for Lanzhou water ecological civilization was established, and this study take Lanzhou City as an example to carry out the evaluation of water ecological civilization degree, so as to judge and solve the key problems. The improved G1 method by combining the entropy weight, coefficient of variation and G1 was used to objectively determine the weight of the evaluation index of water ecological civilization in Lanzhou City. The comprehensive evaluation method of the harmony degree equation (HDE) was used to quantitatively analyze the degree of water ecological civilization in Lanzhou City from 2014 to 2017. In the construction of water ecological civilization in Lanzhou City, the management and publicity of water supervision and water culture should be increased. The values of harmony in 2014-2017 were 0.08, 0.38, 0.72, and 0.94, respectively, indicating the degree of water ecological civilization is significantly improved. The degree of water ecological civilization in Lanzhou City has been increasing year by year. In 2017, it has reached a remarkable civilization. Through the creation of the Yellow River customs line, the water ecological construction effect in Lanzhou City has been obvious in recent years. With the different development stages, it will be accompanied by different focuses, and we should improve the indicator system and propose relevant characteristics of different time periods, to better guide the construction of water ecological civilization in Lanzhou City.
