With the aid of a bulky agroclimate dataset,a system of Agroclimate Resemblance Information(ACRI)is developed.This paper presents a brief introduction to its overall design,principles, functions,further development and prospects.Moreover,the system is able to displayrapidly the recent situation of the resemblance research/application and to provide climate datafrom any part of the world kept in it.Also,based on an array of indices randomly selected,agroclimate resemblance calculation and ordering can be accomplished and,on the other hand,it willbe of help to revealing the acclimation sequence and aplicable domain for animal breeds and plantvarieties to be introduced and diffused.Finally'the ACRI will furnish an agroclimatic basis for agricultural techniques pooling、and research.
