基于ArcGIS伊犁河谷旅游气候舒适度研究

Study on Climate Comfort of Tourism in Ili River Valley Based on ArcGIS

利用伊犁河谷1961—2018年10站逐日平均气温、平均风速、平均相对湿度地面气象观测资料,运用模糊综合评价法和地理信息系统技术,将夏季分为18候并分析各候旅游气候舒适度指数变化特征,进行旅游气候舒适度空间分布特征分析。结果表明:伊犁河谷夏季大部分地区、大部分时间适宜旅游。对于西部县市,整个夏季均适宜旅游;东部的巩留县6月6日—8月25日,新源县6月16日—8月31日,尼勒克县7月6日—8月15日适宜旅游;南部的特克斯7月21—31日和8月6—10日2个时段适宜旅游,昭苏由于气温较低,导致整体旅游气候舒适度不舒适。7月21日—8月10日最适宜在伊犁各地游玩。舒适度较高的区域主要集中在河谷西部和东部的平原地区;整个夏季,伊犁河谷旅游气候适度最好的地区位于察布查尔县北部、霍尔果斯市、霍城县南部、伊宁市、伊宁县西南部、巩留县西北部地区,旅游气候舒适度总体上呈现由平原区向高海拔地区逐渐减小趋势。

Based on the daily average temperature,average wind speed,the average relative humidity of the ground meteorological observation data in Ili River Valley station from 1961 to 2018,through fuzzy comprehensive evaluation method and geographic information system technology,summer is divided into 18 pentad,and the spatial distribution characteristics of tourism climate comfort index are analyzed based on the change characteristics of tourism climate comfort index in each pentad.The results show that:Most of the Ili River Valley is suitable for tourism in most of summer.The whole summer is suitable for tourism for the western counties and cities,eastern Gongliu County from June 6 to August 25,Xinyuan County from June 16 to August 31,and Nilak County from July 6 to August 15.In the south,Tekes County is suitable for tourism from July 21 to 31 and from August 6 to 10,while Zhaosu County is not comfortable due to the low temperature.The period of July 21 to August 10 is the most suitable for tourism in Ili.The areas with higher comfort level are mainly in the western and eastern plains of the valley.In the whole summer,the regions with the best moderate tourism climate in Ili River Valley are located in the north of Qapqal County,the south of Khorgas City,the south of Huocheng County,Yining City,the southwest of Yining County,and the northwest of Gongliu County.The comfort degree of tourism climate decreases gradually from the plain area to the high altitude area.
