宁夏经济增长与环境质量特征分析

Characteristics of economic growth and environment quality in Ningxia

利用宁夏1986-2005年经济与环境数据,建立人均地区生产总值(人均GDP)与典型环境指标关系模型,并分析了两者之间关系。结果表明:宁夏人均GDP与环境指标总悬浮颗粒物(TSP)年均浓度呈线性负相关,与工业废水、工业COD排放量呈现倒U字型或倒N字型,有明显的EKC关系,原因是环保政策成绩显著和工业内部结构调整及企业内部污染治理投资增加;而宁夏人均GDP与工业废气、工业二氧化硫(SO2)排放量和工业固体废物产生量随着经济的发展呈现上升趋势,符合经济发展初期随着经济发展污染物排放量增加的理论,没有明显的EKC关系;而整体来看,宁夏工业废水、工业COD排放量控制政策相对较为成功,但工业废气和工业固废控制政策尚需加强。

The research analyzed the relationship between economic growth and environmental degradation based on the economic and environmental data from 1986 to 2005 in NingXia province. The results showed： the relationship between GDP per capita and TSP levels took on the linearity shoulders a relevance. Industrial sewage and industrial COD discharge amounts with the growth of GDP per capita took on an inverted - reverse the U and N type, having obVious EKC something to do. Environmental policies for conreolling air quality and industrial waste water were successful. The industrial waste gas, industrial discharge amounts of SO2 and the industrial solid waste producing amounts with the growth of GDP per capita displayed upward trend, according with economic growth initial stage with the theory that economic growth discharge of pollutants increase, and having not obvious EKC relation. The industrial sewage, industry COD discharge control policy was relatively successful, but the environmental polices for controlling industrial waste gas and solid waste should be further enforced in NingXia Provice.
