基于因子分析的嫩江重要省界缓冲区水质评价研究

Quality Assessment of Boundary Buffer of Nenjiang River Basedon Factor Analysis Method

嫩江流域省界缓冲区水质监测与评价,是针对2010年和2015年引起嫩江省界缓冲区水环境质量主要污染物的变化分析,判断主要超标指标为有机生化指标。为进一步明确嫩江缓冲区水质影响关键因子,采用因子分析评价嫩江重要省界缓冲区水质状况。依据因子的荷载矩阵,2010年和2015年的主导因子均累计解释了原始向量80%以上的信息,反映了这两年水环境和污染因子之间的关系。嫩江流域省界缓冲区流域水质状况分析,为今后对嫩江流域水功能区目标管理提供理论支持。

Provincial boundary buffers are important means to achieve watershed management. Based on the load factors, the pollution changes in 2010 and 2015 in the provincial boundary buffers along Nen River were discussed to determine that themain organic pollutants were biochemical indicators. To further define the critical factor in Nen River buffer water quality impact, using factor analysis and evaluation of water quality in the Nen River important provincial boundary buffer. Matrix based on load factor, 2010 and 2015 were dominant factors explain accumulated more than 80% of the original vector information reflects the relation-ship between these two factors of water environment and pollution between. Analysis onNenRiver Basin water quality will provide theoretical support for the futureresearch on Nen River watershed.
