本刊八○年第二、三期刊登了两篇评论趋势分析的文章,最近又陆续收到了几篇这方面的稿件。为了贯彻“双百方针”,活跃学术气氛,我们选择了具有代表性的文章予以刊出,以便使地质界从事数学地质的同志更深刻了解趋势分析的一些基本问题。另外,我们也希望对其他多元统计方法在地质中的应用展开讨论。讨论既可互相促进,又可探明问题的实质。百家争鸣是科学兴旺发达的标志。但愿所辟的版面能成为百花争艳的园地。 The second and third issues of the magazine published two articles on trend analysis of reviews in 1980 and recently received several articles in this area. In order to carry out the “two hundred principles” and to revitalize the academic atmosphere, we have chosen a representative article to publish so that geophysical geologists in the geological field can understand more deeply some basic problems in trend analysis. In addition, we also hope to discuss the application of other multivariate statistical methods in geology. Discussions can promote each other as well as the substance of the problem. A hundred schools of thought contend that science flourishes. I hope the layout can be turned into a blooming field of flowers.
