杨梅群落与杉木群落气候舒适度的比较评价

ACOMPARATIVE EVALUATION OF CLIMATE COMOFRT BETWEEN Myrica rubra COMMUNITY AND Cunninghamia lanceolata COMMUNITY

对比分析浙江农林大学东湖校区杨梅群落与杉木群落下层的小气候差异和气候舒适度等级。分别于2009年5月、7月、10月及2010年1月各选择2个晴天定点同步测定杨梅Myrica rubra群落和杉木Cunninghamia lanceola-ta群落内小气候因子。研究结果表明:7月和10月杉木群落下层气温高于杨梅群落,且1月杉木群落下层昼间气温波动幅度也比杨梅群落大;5月、7月和10月杨梅群落的相对湿度略高于杉木群落,而1月则以杉木群落较高,且波动幅度更大;两个森林群落内风速日波动幅度较大,其中以杨梅群落风速观测值的极差明显大于杉木群落;杨梅群落的气候舒适等级高于杉木群落。

Microclimate differences and climate comfort degree between Myrica rubra community and Cunninghamia lanceolata community in Zhejiang Agriculture and Forestry University＇s East Lake campus were evaluated comparatively.The study have determinated synchronously the microclimate factors of M.rubra community and C.lanceolata community in two sunny days of spring,summer,autumn in 2009 and winter in 2010.The results showed that： the lower forest temperature of C.Lanceolata community in summer and autumn were higher than that of M.rubra community,and temperature fluctuation of C.Lanceolata community during daytime in winter was higher than that of M.rubra community;relative humidity of the spring,summer,autumn of M.rubra community were little higher than that of C.Lanceolata community.While in winter,C.lanceolata community had higher temperature and greater fluctuation;two forest communities have great fluctuations in wind speed,maximum minus the minimum of wind speed of M.rubra community was significantly greater than C.Lanceolata community;M.rubra community＇s climate comfort level was higher than that of C.Lanceolata community.
