%X In this paper, Authors apply measured data of Marshal Line apple's quality to research correlation about apple's qualities (such as sugar content, sour content, hardness etc.) with climatic belt in different altitude. The results inditated that 1.0-1.5km above sea level in the North of Weihe River among hte Loess Plateau is optimum climatic region of high quality apples in our country. The climate and soil ecotype in this belt are adaptation to develop production o'f high quality apples and should be built a base of economical production.
