采用数据挖掘技术分析出影响地表土层地温的因素依次为日照、地下水埋深、潜水蒸发量、降水入渗补给量等,因而得出了在一定深度范围内地下水位变化对近地表地温影响较大,从而提出了地下水热岛效应的概念。基于突变理论给出了漏斗区地下水热岛效应临界埋深的判据,提出了热岛效应临界埋深及临界面的概念,据此确定了热岛效应临界埋深值,最后给出了地下水热岛效应图。
Data mining techniques to analyze the impact of surface soil temperature were sunshine, groundwater depth, phreatic water evaporation, rainfall infiltration recharge, etc., and thus come to a certain depth of the groundwater level changes on the impact of near-surface temperature Large, thus put forward the concept of groundwater heat island effect. Based on the catastrophe theory, the criterion of the critical buried depth of the groundwater heat island effect in the funnel is given, and the concept of the critical depth of the heat island effect and the critical surface is proposed. Based on this, the critical buried depth of the heat island effect is determined. Finally, .
