新构造运动对安徽土壤分布的影响

安徽地跨亚热带与温带，过渡性特征明显，境内有山地，丘陵和平原，自然地理景观复杂多样，各区域由于所处大地构造单元不同，其新构造运动的表现形式也不同，它制约着区域地貌的发育，成土母质类型和地面气候状况，从而影响了该区域土壤的分布特征。

EFFECTS OF NEOTECTONIC MOVEMENT ON SOIL DEVELOPMENT AND DISTRIBUTION IN ANHUI PROVINCE

Anhui province is located between the subtropical zone and temperate zone with clear features of transition.There are three kinds of landforms in Anhui province:mountain,hills and plain.The natural environment is complex and diversified in the study area.Because of the difference of tectonic elements in different regions,the manifestation of neotectonic movement varies,and conditions the development of regional landform,the distribution of parent materials and the changes of ground climate,thus it influenced the distribution characteristics of soils in Anhui.This paper discusses effect of three kinds of crustal movement in the neotectonic period,i.e.,extensive downthrow,extensive upthrow and difference movement of fault block along both sides of deep fracture zone,on the development and distribution of soils in Anhui.
