浙西山地森林小气候变化特征及其对休闲旅游活动的影响

CHARACTERISTICS OF FOREST MICROCLIMATE IN THE MOUNTAINS OF WESTERM PART OF ZHEJIANG AND ITS EFFECTS ON THE LEISURE TOUR ACTIVITY

采取两个空间序列,即杭州武林广场-东湖校区-天目山常绿阔叶林和天目山毛竹林-紫楠林-柳杉林,研究海拔和森林植被类型驱动下山地小气候的日进程。结果表明:(1)秋末和夏初,紫楠群落内气温和相对湿度的日波动幅度较东湖校区和武林广场大,紫楠群落内气候舒适等级明显小于低海拔地段武林广场和东湖校区。(2)在天目山自然保护区,毛竹群落内气温较高,毛竹群落内风速日波动幅度平稳,紫楠群落风速日波动幅度较大,柳杉群落风速日波动幅度亦较大;紫楠群落和柳杉群落的气候舒适等级高于毛竹群落。所以,气候舒适等级日持续时间从低海拔生境向高海拔生境不断延长。

The characteristics of the microclimate of mountain in western part of Zhejiang province of China were analyzed by using the spatial series, that is from Wuling square in Hangzhou, Donghu campus in Zhejiang Forest College to evergreen broadleaved forest in Tianmu mountain, and from Phyllostachys edulis community ,Phoebe sheareri community to Cryptomeria fortunei community respectively. The results showed that ： 1 ） The diurnal changes of temperature and relative humid in Phoebe sheareri community were larger than that of Wuling square and Donghu campus at the late autumn and early summer, and meanwhile the climate comfort degree in Phoebe sheareri community was much higher than that of Wuling square and Donghu campus. 2）In national nature preservation area of Tianmu mountain, Zhejiang Province, the air temperature in Phyllostachys edulis community was higher than that of the other two types of forest community, the wind speed amplitude in Phyllostachys edulis community was steady, the wind speed amplitude in Phoebe sheareri com- munity and Cryptomeriafortunei community was also larger. The climate comfort degree in Phoebe sheareri community and Cryptomeria fortunei community were much higher than that of Phyllostachys edulis community. The duration of climate comfort degree at daytime has been prolonged from lower elevation to higher elevation in April, May and June in national nature preservation area of Tianmu mountain, Zhejiang Province.
