Abstract: Experimental analysis shows that owing to be different ecological climates in Hexi Corridor’s areas，the apple pear has obvious regional distribution and temporal characters，and shows different growing habits and quality properties．The growth and development of apple pear show a certain difference yearly because of disequilibrium of meteorological factors distribution in every year．The growing trend of appl-pear fruit shows “S” typical increasing curve．According to this curve，we can computer that the fruit productivity is the largest between the last ten days of July and the middle ten days of August．The suitable temperature of fruit swelling is 15～ 21℃ ．The whole growing period needs to pass≥ 7℃ and accumulating temperature steadily that is 2300～2800℃．The qualities’forming period (from the first ten days of September to the first ten days of October)needs cool climate．Within the suitable temperature，there are big daily temperature’S difference and enough sunlight which are in favor of good quality and accumulation of soluble so lidity’S content．On the basis of analysis on the main meteorological restricting factors that affect the apple-pear’S yield and quality，the Hexi Corridor is plotted into five climate suitable growing areas．
