The present paper deals with further classifying the soil basic types of red earth developed from the red clay materials of Quaternary era in Kinhwa basin,Chechiang Province.In this region the red earth lies on the gentlely rolling to undulating topography about 8 to 50 meters above the main river course.Most of the soils are covered under shrubs and grasses.Owing to the variation of soil properties,the capability of utilization of these soils is quite different.Some of them become more fertile and give good harvests after cultivation;but some of them lose their fertility due to severe erosion after successive plantation.Twelve basic types of red earth are classified on the basisof the following variations:1.Variation in parent materials.
