- 城市气候舒适度的研究对城市区域气候变化及旅游业发展具有重要意义。根据气候舒适度评价模型,通过插值法对四川省城市气候舒适度和舒适期进行综合区划和评价以及通过熵值法和百分位法利用海拔差异对气候舒适度进行有效订正。研究表明:气候舒适度具有显著时空分布差异,舒适期空间分布差异大。经海拔订正后舒适度分布:平均海拔低于500 m地区春秋较舒适,冬夏较不舒适; 500～1000 m地区冬夏较舒适,春秋舒适; 1000～2000 m地区四季均为舒适; 高于2000 m地区均较差。
- Abstract:
- It is greatly important to research the urban climate comfort for regional climate change and tourism development. According to the climate comfort evaluation model, the comprehensive zoning and evaluation for climate comfort and comfort period is made through the use of interpolation method in this paper. The altitude difference is used to effectively revise the Sichuan climate comfort by the entropy method and percentile method in the paper. The results can be concluded as follows: Firstly, the climate comfort in Sichuan has obvious difference in spatial and temporal distribution; Secondly, comfort period has obvious difference in spatial distribution; Thirdly, the spatial distribution of the comfort after being corrected by the elevation is: the climate comfort of spring and autumn is a bit comfortable and the climate comfort in summer and winter is a bit uncomfortable in the region under 500m, the climate comfort in spring and autumn is comfortable and the climate comfort of summer and winter is a bit comfortable in the region between 500 m and 1000 m. The climate is comfortable in the whole year in the region between 1000 m and 2000 m, and the climate comfort is terrible in the whole year in the region above 2000 m.
