Abstract: It is significant of the weather resources comprehensive assessment for winter wheat introduction and suitability evaluation.This paper establishes the indexes and system of winter wheat weather resources comprehensive assessment,which is based on Hierarchy Analyzing Process and realizes the changes from the qualitative evaluation to quantitative evaluation.And the method was applied in Tang Shan city.The comprehensive wheat weather resources is a relative bad(G=2.71),because of the lack of precipitation resources(G=1.0) in winter wheat midseason and the lower soil humidity index(G=1.92),however the heat resource(G=3.61),wind speed and sunshine resource(G=3.47) is relative high.

Key words: Winter wheat, Analytic Hierarchy Process, Assessment of climate resources, Suitability
