土壤的粒级组成影响着土壤的理化性质,本文是采用比重计法对西南区几种岩成土壤（紫色土、石灰土、火山灰土）的粒级进行测定分析.得出以下结论：
⑴西南区岩成土,紫色土、石灰土和火山灰土的颗粒砂粒所占比重大,粘粒、粉粒所占比重较小.
⑵同一土壤间不同土层,由于淋溶淀积等作用的影响,土壤上下层的粒级组成存在一定差异,黑色石灰土的砂粒和粘粒的含量随着深度的增加而增多.而火山灰土的砂粒和粘粒含量随着深度的增加而减少.
⑶不同地点同一土壤由于风化作用、淋溶作用和人类活动的影响程度不同,土壤粒级组成存在一定差异.
⑷不同土壤同一土层,由于成土的岩石不同,砂岩发育的土壤含砂多,石灰岩、泥岩发育的岩石粘粒多.
⑸同一土类不同亚类的土壤,颗粒组成也不同,但大趋势相似.

Soil grain grade composition of soil physical and chemical properties of influence,this is the method of using BiChongJi southwest area into several rock soil (purple soil,lime soil,volcanic dust) grain grade.Some conclusions:
Southwest area into rock (soil,lime,purple soil and volcanic dust particles in the sand,which accounts for more than viscous grain powder,small proportion.
2 the same soil layer,due to the different leaching deposition etc,on the effect of soil layer of grain composition class there are differences of sand soil,black limestone and clay content with the increase of depth and increased.And the sand and volcanic ashes viscous grain content decreased with depth.
3 the soil due to different locations eluviation weathering,the influence of human activity and the degree of different level,the soil grain composition there is some difference.
4 different soil layer,due to the different soil of rock,soil contains sand development of sandstone and mudstone limestone,development of viscous grain rock.
5 the same soil types,different sub-types of soil particle composition is different,but the trend is similar.
Keywords:rock into the soil,The soil profile,Grain grade,Determination
