运用SPSS软件中的多元线性回归分析模型．对北京动物园水体富营养化影响因子进行了逐步回归分析。通过模型分析可以确定在水质改善工程实施过程中的各个时期、阶段影响湖泊富营养化的关键因子，从而为下一阶段更加科学有效地实施水质改善工程提供了依据。在水质改善工程实施的几个不同阶段，分别有不同的关键因子影响湖泊富营养化，依次分别是叶绿素a、溶解氧、透明度及氨氮；个别阶段则是多个因子共同影响湖泊富营养化，没有关键因子。

The impact factors of eutrophication in the water body of Beijing zoo was analyzed by using multiple linear regression model of the SPSS software. Through the analysis, it were determined that the key factors of eutrophication in each period and stage of the water quality improvement project. It could be provided a reference for the scientific and effective implementation of water quality improvement in the next phase. In different stages of the water quality improvement project, key factors affecting eutrophication were different. The key factors were chlorophyll a, dissolved oxygen, transparency and ammonia nitrogen. In individual stages eutrophication were affected by multiple factors, and there were no key factors in these stages.
