Other Abstract 以气象资料为基础,为土壤系统分类的需要,估计了四川盆地紫色土的温度状况,采用逐步回归方法,从与土温相关的10项气象因素中,筛选出6项主要影响因素。根据本区土层浅薄的特点,建立了不同深度土层的土温计算方程。计算结果表明,按土壤系统分类的土温状况诊断标准,本区拥有热性土壤温度状况。 
; Based on meteorologic data the temperature regime of purple soil in Sichuan Basin was estimated for the application of soil taxonomic classification. Mean annual values being taken as variables,168 series of data were collected from 14 meteorologic observation stations.6 major factors were chosen out of 10 meteorologic ones by means of the successive regression method. In the light of the fact that the thickness of soil layer is thin in most of the region,the caiculation equations of soil temperature for different controlicd temperaturc soil layers Within 50cm depth beneath soil surface were established. For the soils of≥30cm in thickness,their temperature can be calculated in accordance with mean annual air temperature, relative humidity , evaporationeapacity and total cloud Cover;whereas,for those of <30cm in thickness,the same can be doneonly with the latitude, mean annual air temperature and wind velocity. Compared with other methods of soil temperature estimate, the present method ischaracterized by the following:1.Temperature regune for different soil layers was estimated , which was of signifieance to hilly regions with thin soil layer.2. It provided a reference for someplaces in which the monthly change of soil temperature needs to be known,for the predictionequations can be not only used to calculate mean annual soil temperature, but alse to calculatemean monthly soil temperature. 3.So far as the application of soil taxonomic classification isconcerned,the prediction equations were of high precision , while they contained fewer factors.It was concluded that the present region belonged to the thermic soil temperature regime(15 22℃)from the results of soil temperature in different parts of Sichuan Basin.
