摘　　要：复杂地形导致的小气候多样,使得很难对一个地形复杂区域的旅游气候适宜度进行一个量化的评估。针对这种情况,文章以重庆市为例,从气候各要素空间分布的特点出发,在数字高程模型(DEM)和气象观测资料的基础上,利用GIS技术结合气象要素空间扩展模型分别对气温、日照、风速、相对湿度进行了空间化,在此基础上计算了三峡库区(重庆市)有效温度指数和风效指数的精细化空间分布,并利用相关资料进行了验证,结果表明使用模型计算的有效温度和风效指数空间分布结果要优于直接使用空间插值的结果。最后,在特吉旺法相关指标的基础上,结合重庆市实际情况和ARCGIS的空间分析功能,对重庆市旅游气候适宜度进行了分类,制作了重庆市旅游气候适宜度精细化的空间分布,并描述了其特点。It is difficult to conduct a quantitative assessment of the comfortable for tourism over the rugged areas for the all kinds of diverse climate leading by the terrain. In light of this situation, the article calculated the spatial distribution of temperature,sun shine duration,wind speed and relative humidity with the help of GIS technology and the space expansion models,based on meteorological observation data and digital elevation model （DEM）. Basing on the results,we calculated the spatial distribution of temperature-humidity index and wind effect index in Chongqing and verified them by the relevant information. The results show that the spatial distribution of the temperature-humidity index and wind effect index by models is superior to results of the direct use of space interpolation, with the Method of W. H. Terjung,the article classified the comfortable climate for tourism in Chongqing and get the fine spatial distribution of comfortable climate for tourism, and describes its the characteristics too.
