最小二乘法曲线拟合在温室效应研究中的应用

通过对1860年到1980年的11个地球平均温度增加值的分析，利用数学中的最小二乘法进行曲线拟合，通过精确计算，建立了地球平均温度增加值与时间之间的函数关系。得出在2080年左右，地球的平均温度会比1980年上升约6℃，从而引起了诸如冰川后退、海平面上升等一系列严重的环境问题。到时极地冰盖就会融化，从而引起大量的洪水泛滥和大片的陆地被淹没，这一认识对进行环境质量评价和提出保护地球的措施具有重要的理论意义。

Application of Least Square Modeling in the Study on Greenhouse Effect

With 11 discrete data of average increasing temperatures of the earth occurring from 1860 to 1980, an empirical model has been established through the use of least square modeling algorithm to predict the increase of earth temperature. This model predicts that the average earth temperature will approximately increase 6＂C by the time around 2080, compared with the average earth temperature in 1980. As a result, this would lead to a series of severe environmental problems such as the retreat of glaciers and the increase of sea --level, and even further cause natural disasters such as heavy flood and disappearance of coast land. The creation of this model is significant in terms of environmental evaluation and environmental protection.
