以榆林市为例,利用典型相关分析、IIISNE及空间分析相结合,定量分析了1996—2014年能源开发区产业结构演变对环境影响。研究表明:榆林市以1998年为拐点,三次产业结构由41.5∶30.3∶28.2转变为4.8∶68.3∶26.9;产业结构的环境影响指数均值高达2.86,属中上水平,并呈现出不断提升态势。其中,第二产业对环境总体影响程度最大,第三产业影响程度最小。IIISNE在空间上南北差异显著,北部煤炭资源富集区较高,且较严重区域呈现加速集中态势。
Taking Yulin City as an example, this paper uses Canonical Correlation Analysis, IIISNE and spatial analysis to quantitatively analyze the environmental impact of industrial structure evolution from 1996 to 2014 in the energy development zone. The results show that: Yulin City, 1998 as an inflection point, the three industrial structure changed from 41.5: 30.3: 28.2 to 4.8: 68.3: 26.9; the environmental impact index of industrial structure reached as high as 2.86, belonging to the upper level, and showing a continuous improvement trend. Among them, the secondary industry has the greatest impact on the environment and the tertiary industry has the least impact. IIISNE has significant spatial and spatial differences between north and south, with a high concentration of coal resources in the north and a more concentrated concentration in more severe regions.
