【摘要】：为深入分析区域环境经济系统变化,在分析经济发展、环境污染、环境质量相互关系的理论基础上,构建了经济发展水平指数、环境污染指数、环境质量指数的三维立方体评价模型,划分了8个块区,分别表达低污染-低质量-低经济发展水平等8种状态,提出了模型的状态评价、发展阶段划分、演变趋势分析功能,以及相对含义、绝对含义评价途径和计算公式.以宁夏银川市为例检验模型,以广州市为目标参照区域进行了相对含义评价,该市1996~2010年内中长时段处于高污染-低质量-低经济发展水平状态,2007年以后转入了高污染-高质量-低经济发展水平,目前处于环境质量趋好、污染压力大、徘徊于环境低质量与高质量"拐点"附近状态.绝对含义评价结果:1996~2010年,该市始终处于高污染-低质量-低经济发展水平.研究表明,因目标参照区域选择和相关国家标准值等主要参数不同,使模型评价具有一定的弹性范围,无量纲的数据处理增强了指数耦合性,评价结果的空间可视化为环境管理决策提供了直接依据,改善了多指标模型评价结果抽象、数据口径不匹配、发展阶段划分不明确等问题,验证了该模型的应用合理性与适应性.
[Abstract]:In order to deeply analyze the change of regional environmental economic system, on the basis of analyzing the relationship among economic development, environmental pollution and environmental quality, the index of economic development level and the index of environmental pollution are constructed.Three dimensional cube evaluation model of environmental quality index is presented, which is divided into 8 blocks, representing eight kinds of states, such as low pollution, low quality and low level of economic development, etc. The functions of state evaluation, development stage division and evolution trend analysis of the model are put forward.And relative meaning, absolute meaning evaluation approach and calculation formula.Taking Yinchuan City of Ningxia as an example to test the model and taking Guangzhou as the target reference area, the relative meaning evaluation is carried out.The city was in the state of high pollution, low quality and low economic development level in the middle and long period from 1996 to 2010. After 2007, the city turned to the high pollution, high quality and low economic development level. At present, the environment quality is getting better and the pollution pressure is great.Hovering in the environment low-quality and high-quality "inflection point" near the state.From 1996 to 2010, the city was always in the level of high pollution, low quality and low economic development.The research shows that the model evaluation has a certain elastic range because of the difference of the main parameters such as the target reference region selection and the standard value of the relevant countries, and the dimensionless data processing enhances the exponential coupling.The spatial visualization of the evaluation results provides a direct basis for environmental management decision-making, improves the abstraction of the evaluation results of the multi-index model, the mismatch of the data caliber, the unclear division of the development stages, and so on.The rationality and adaptability of the model are verified.
