摘要
因子分析模型是用少数不可观测的变量来解释原始变量间相互关系的一种数学模型。本文采用因子分析模型,对我国各地区大量工业及生活排放污染物数据进行了计算分析,得到了各地区单项污染和整体污染分析结果,最终在全国环境污染专题地图中得以应用。实验证明,因子分析模型能简化数据结构,减少信息冗余,发现环境污染的主要因素,为各地区环境整治提供了科学、准确的量化指标。
Factor Analysis Model is a mathematics model which can explain the relationship between the original variables by using a few unobservable variables. This paper adopts the Factor Analysis Model to calculate and analyze a large number of data on industrial and community pollutions in every area of our country and then gets the analyzed results of single and whole pollution in each area. Finally, it applies the model in thematic mapping on environment pollution in the whole countl7. The experiment shows that the Factor Analysis can simplify the data structure, decrease the information redundancy and figure out the major factors of environ- ment pollution so as to provide with every area a scientific and accurate standard on controlling the environment pollution.
