新疆维吾尔自治区策勒县绿洲一沙漠过渡带小气候特征
Microclimatic Characteristics of Oasis-Desert Transitional Zone in Qira County of Xinjiang Wei Autonoumous Region
摘要
Abstract
Wind velocity,air temperature,air relative humidity,photosynthetically active radiation were synchronously monitored using HOBO Portable-Meteorological Stations in the three nature communities including Tamarix ssp community,Tamarix ssp—Alhagi sparsifoli—Karelinia caspica community,Alhagi sparsifolia community in the oasis—desert transitional zone of Qira County between July 23 and August 24,2010.The difference of microclimate among the three plant communities was analyzed.The results show that the vegetation in the transitional zone has particular partial climate effect.With increase of vegetation coverage,wind speed and air temperature decreased,and relative humidity increased.The vegetation covers in communities of Tamarix ssp,Tamarix ssp—Alhagi sparsifolia—Karelinia caspica,and Alhagi sparsifolia were 3%,27%,and 67%,respectively.During the observation period,the average wind speed at 0.5,1,2,4,8,and 10 m high in Tamarix ssp—Alhagi sparsifolia—Karelinia caspica community and Alhagi sparsifolia community were 32% and 47% lower than that in Tamarix ssp community;specifically,the average wind speed at 0.5 m high was 57% and 47% lower,respectively.In communities of Tamarix ssp—Alhagi sparsifolia—Karelinia caspica and Alhagi sparsifolia,the average air temperature（2 m high） were 0.32 ℃ and 1.02 ℃ lower,and the average air relative humidity（2 m high） were 2.33% and 7.67% higher than those of the Tamarix ssp community,respectively.However,the photosynthestically active radiation had no significant difference between the three communities,although it was 40% and 60% lower on cloudy days and dust storms than that on clear days,respectively.关键词
