解析:地表自然地理现象的分布,并不都具备地带性分布规律。它们有的既可分布在较低纬度,也可分布在较高纬度;既可在一个地带性自然带中存在,又可在几个地带性自然带中存在。例如湖泊这一地理事物,既可分布在温带森林中,也可出现在亚热带常绿阔叶林或萨瓦纳里;又如绿洲,既可在温带沙漠中出现。又可在热带沙漠中出现等等。那么,究竟哪些因素产生了非地带性分布呢?概括起来有如下几类:
Analysis: The distribution of surface physical geography does not always have zonal distribution rules. Some of them can be distributed either at lower latitudes or at higher latitudes; they can exist in one zonal natural zone or in several zonal natural zones. For example, the geography of lakes can be distributed in temperate forests, in subtropical evergreen broad-leaved forests or in Savannas, and in oasis they can occur in temperate deserts. Can appear in the tropical desert and so on. So, what factors have produced a non-zonal distribution? Summarized as the following categories:
