    This paper attempts to interpret, from a single point of view, several at first sight independent phenomena brought into focus through the investigations of the relationships among the earthquakes, the precipitations, the soil heat flows and deep-layer heat flows carried on at the Lanzhou Institute of Plateau Atmospheric Physics during last few years. Since this interpretion is very largely based on a consideration of that some changes occured inside the lithosphere play a fundamental role in the climatic system variations which is of a longer than ten years time-scale, the results would appear to be of enough interest to geophysists and meteorologists to research and predict the natural disasters such as the earthquakes, the floods and the droughts theoretically and appliedly. The particular phenomena brought out in the course of our studies are listed below:
    1)The averages of many years soil heat flow calculated with the methods which was designed according to linear thermal conductive theory are of sufficiently computational precision being appropriate to the requirement for further analysis.
    2)There are the great similarities among the distributions of,the mean soil heat flows, deep-layer soil heat flows and the earthquake bands .In most of the place where so enough observed data and computed values had been obtained that one can make comparisons among them, it is easy to find that where is a high value band or area in the mean soil heat flow isoline chart there must have been the high band or area as well in the deep-layer heat flow isotimic map and the distribution map of the earthquake bands.
    3)The variations of soil heat flow anomalies,which normally take relationships with the precipitation and the earthquake in the following, would provide geophysists and weather men a great help to forecast the natural disasters.
