摘  要:
基于广东省1965~2007年78个县气象站点的气象数据,以经纬度、海拔高度、水分和热量等为气候主要影响因素,构建"回归分析+残差修正"模型。然后采用反距离加权法对气候要素进行空间插值,以1?×1?栅格为评价单元,分别对年平均气温、大于10℃积温、干燥度、年降水量和年降水变率等因子进行分析评价。最后,采用AHP决策分析方法对气候进行综合评价,揭示广东省不同地区的气候条件及空间格局。

摘  要:
According to the meteorological data of 78 key meteorological stations during 1965 and 2007 in Guangdong Province,with latitude and longitude,altitude,water and heat as the main factors of climate,this study aimed to respectively analyze the annual mean temperature,accumulated temperature over 10 ℃,aridity index,annual precipitation and annual precipitation variation by building the "regression analysis of the residual + amendments" model and then in each sub-area,using the method of Inverse Distance Weighted(IDW) to interpolate meteorological data with a grid of 1km×1km as an evaluation unit.Finally this essay comprehensively evaluated the climate with the method of analytic hierarchy process(AHP) and revealed the climatic conditions and space patterns in Guangdong Province.
