丽水市避暑选址气候适宜性综合评价

Climate Suitability Evaluation on the Siting of Summer Resort in Lishui City

通过对20102019年丽水全市近10年气象站夏季逐日地面观测气象资料,采用经验贝叶斯克里金(EBK)回归/EBK插值进行空间分析,从温度、湿度和风速等避暑气候条件对丽水市避暑气候资源开展单因子分析,并进一步通过温湿指数和人体舒适度指数对丽水市避暑适宜地空间分布进行综合评价。结果表明,丽水市避暑资源空间分布不均,位于丽水西南面和西面的庆元、景宁、龙泉和遂昌平均气温低、高温日数少、温湿指数和人体舒适度指数舒适区域面积大,适合避暑开发的区域多,其余区县虽然适宜避暑的区域面积不大,但均有分散的可开发避暑区域。全市最适宜避暑的区域集中在海拔较高的龙泉和庆元交界处,其中庆元县百山祖镇适宜避暑区域面积最大。此外,根据避暑气象要素指数,筛选出丽水市最适宜避暑的15个乡镇。

In this study,we evaluate the spatial distribution of suitable summer resort areas in Lishui City based on the daily meteorological data in summer(June to August)from 2010 to 2019.By using Empirical Bayesian Kriging(EBK)regression/EBK interpolation,the single climate factor analysis of temperature,relative humidity,wind speed and the comprehensive analysis of temperature-humidity index and human comfort index are performed.The results show that there are many potential summer tourism destinations in Lishui City,but the spatial distribution of summer resort resources is uneven.The counties of Qingyuan,Jingning,Longquan and Suichang located in the southwest and west of Lishui have lower average temperatures,fewer days of high temperature,larger suitable areas of temperature-humidity index and human comfort index,so these places are more suitable for summer resort development.The other districts and counties also have some scattered areas for summer resort although the suitable areas are relatively smaller.The most suitable areas for summer resort are concentrated in the high-altitude junction locality of Longquan and Qingyuan counties of Lishui City,of which Baishanzu Town in Qingyuan County has the largest area suitable for summer resort.In addition,according to the summer meteorological elements index,the most suitable 15 towns in Lishui city are selected.
