摘要:
利用SPSS统计软件分析宁夏“十一五”期间主要污染物总量控制指标与环境质量数据的关联程度,并建立回归模型。结果表明:宁夏总量减排与环境质量改善存在高度关联,拟合曲线均为一元线性回归曲线。随着SO2排放总量降低,重点城市空气质量稳步改善,两者呈现同向变化的趋势;随着COD排放总量降低,黄河宁夏段水环境质量稳步改善,两者亦呈现同向变化的趋势。宁夏总量减排在环境质量改善上成效已显现,污染防治政策较为成功,环保成绩显著。

Data analysis on the correlation between the total emission reduction and characteristics of environmental quality improvement in Ningxia
Abstract:
A regression model was built by the analysis on the correlation degree between the total emission reduction index of major pollutants and environmental quality in Ningxia using SPSS statistical software. The results showed that there was a high correlation degree between the total emission reduction and characteristics of environmental quality improvement in Ningxia. The fitting curves were all linear regression curves. The air quality improved steadily with the reduction of sulfur dioxide emission. The water quality in the Yellow River of Ningxia section also improved with the reduction of COD emission. There were both positive correlations. The improvement of environmental quality in Ningxia was effective due to the total emission reduction. The policy of pollution control was rather successful.
