摘要
通过对淮河安徽段各城市水质及其相应产业密度的分析,以产业密度为自变量,以区域水污染综合指数为因变量,得到水质与产业密度的关系拟合曲线。通过对曲线形状分析表明:淮河安徽段各地、市虽已处于良性发展阶段,但仍需进一步巩固治污成果,其主要支流的水质状况还不容乐观;依据时空等价模型,应积极引导经济发展程度低的城市在未来发展中按曲线展示规律转变;此外,为保护水环境和实施区域的可持续发展,必须大力调整产业结构,提高产业的技术水平和加大对水环境的治理力度。
Water quality and industry density of the cities in Anhui section of the Huaihe River are analyzed. A fitting curve on the relationship of water quality and industry density is found, with industry density and water quality being independent variables and dependent variables respectively. Analysis indicates that, although regions in Anhui section of the Huaihe River are in good state of development, water quality in main tributaries is not satisfactory, and pollution control should be strengthened. Future development of underdeveloped cities should follow the tendency demonstrated in the curve based on the spatial-temporal equivalence model. Furthermore, industrial construction adjustment, technique improvement and water contaminant treatment should be taken for the protection of water environment and sustainable development of the region.
