【摘要】 用主分量分类分析方法对广西2001—2015年各要素环境质量监测指标与自然、经济、人口、能源和污染物排放等年鉴统计指标构成的综合环境质量结构与功能属性关系进行耦合。结果表明:广西综合环境质量在省域层次上呈现明显的年、季、月等时间尺度变化规律。在市域层次上,年际时空交互变化规律分异明显;月份的时空交互变化规律在城市空间格局上有明显分异,但时间序列的分异规律不明显;季度的时空交互变化规律在空间与时间上均无明显分异。研究可为经济发展、国土空间优化、能源利用、环境保护等决策管理与判别提供参考。更多还原

【Abstract】 The inherent relationships between the structure and the function of the comprehensive environmental quality in Guangxi,which matrixed by 15 years’ data sets among environmental quality monitoring indices on air,water,pollution sources,ecological environment,and statistical indices of yearbook concerning nature,economy,population,energy,pollution discharges in Guangxi are analyzed using category principal components analysis. It is found that there are significant temporal differences in the dynamic changes both during the periods of years,seasons and months for the comprehensive environmental quality of Guangxi at total unit level. While at city unit level,the comprehensive environmental quality presents significant spatial-temporal variation during the periods of year. Meanwhile,it shows only spatial resolution during the periods of month. However,it displays insignificant spatialtemporal resolutions during the periods of season. It will provide references to the decision management and discrimination on regionally economic development,environmental protection,land and resources exploration and utilization in the near future.更多还原
