摘要: 冬小麦气候资源综合评价对于冬小麦引种与种植适宜性评价有重要意义。本文构建了基于层次分析法的冬小麦气候资源综合评价指标与体系,实现了对冬小麦气候资源评价由定性描述到定量评价的转变。对唐山地区冬小麦气候资源进行了实证评价应用,结果显示:该地区冬小麦综合气候资源比较差(G=2.71),表现在冬小麦生长期间降水资源非常缺乏(G=1.0),土壤湿度指标较低(G=1.92),但热量资源、风速与日照资源评价值高(G值分别为3.61和3.47),结果与实际情况基本一致。

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
