选取温湿指数和风效指数模型,基于GIS技术,在1 km ×1 km栅格尺度上评价安徽省气候适宜性,研究结果显示:安徽省风效指数显示全省绝大部分地区处于舒适或较舒适等级,温湿指数值介于25.94-81.56之间,空间以及时间差异较大;从空间分布来看,安徽气候适宜性受纬度和地形等影响,南部气候相对较舒适,淮河以北、皖西和皖南山区相对较不舒适;从年内变化来看,安徽省88.47%的地区舒适期为5个月,其中10月是全年最舒适月份;安徽省气候适宜性呈现和人口分布特征不一致。安徽省气候适宜性程度主要是受纬度、地形、水文等因子的影响。
選取溫濕指數和風效指數模型,基于GIS技術,在1 km ×1 km柵格呎度上評價安徽省氣候適宜性,研究結果顯示:安徽省風效指數顯示全省絕大部分地區處于舒適或較舒適等級,溫濕指數值介于25.94-81.56之間,空間以及時間差異較大;從空間分佈來看,安徽氣候適宜性受緯度和地形等影響,南部氣候相對較舒適,淮河以北、皖西和皖南山區相對較不舒適;從年內變化來看,安徽省88.47%的地區舒適期為5箇月,其中10月是全年最舒適月份;安徽省氣候適宜性呈現和人口分佈特徵不一緻。安徽省氣候適宜性程度主要是受緯度、地形、水文等因子的影響。

Supported by GIS technology ,it maked quantitative evaluation of climate suitability for human settlement of Anhui province based on temperature humidity index (THI) and wind chill index (K) at a lkm×lkm grid size ,and the main conclusions are as follows:based on analysis of K ,the area of suitable climate includes most area of Anhui province ,THI is between 25.94 and 81.56.The regulars of space distribution of the climate cuitability are controlled by the changes of latitude ,terrain,hydrology,etc.Are-as along the Yangtze River are the best comfortable climate regions;while areas to the north of Huaihe River,Dabie Mountains and Huangshan Mountainous are the most uncomfortable areas in terms climate . The predominant length of climate suitability in Anhui province is five months per year ,while October is the most suitable month .The spatial distribution pattern of natural suitability of climate suitability is con-trast with the populations'.
