摘要
舒适度是衡量一个地区是否适宜开展旅游活动的重要指标.基于宁夏2008—2018年25个气象观测站的平均气温、相对湿度、风速,以人体舒适度指数(k ssd)为指标,计算全省及各市的逐日人体舒适度指数,分析全区旅游气候舒适度的年、季变化以及空间分布特征.结果表明,全区平均人体舒适度指数主要集中在1~6级,即寒冷、冷、凉、凉爽、舒服、稍热、热,没有炎热及酷热,大部分时间表现为舒适到偏凉的体感状态;舒适度指数空间分布特征明显,冷、凉等级时间上南多北少,而舒适时间却是北多南少;六盘山海拔较高的区域全年体感为冷和凉的状态,不适宜旅游,而中北部4市的4—9月、地处六盘山区的固原市的5—9月为凉爽到舒适的体感状态,适宜开展户外活动;各地夏季适宜旅游的时间最多(68.6~79.0 d),占夏季的76.2%~87.8%,适合避暑;其次是春季和秋季,适宜户外活动的时间分别为30.3~51.2,26.8~40.1 d;冬季各地冷不舒适特征明显,不太适宜旅游.
