摘　　要：总结并分析了和田绿洲近40年的气象资料,经研究发现绿洲小气候存在着变暖、增湿、风速降低的趋势,跟新疆整体气候变化相一致。这一变化使和田绿洲上空大气边界层升高,对绿洲的保护范围加大,绿洲感热通量变小,潜热通量变大,湿度增强。和田地区由于人类活动和自然条件的变化,生态环境遭到破坏,而绿洲小气候的变化趋势则有利于优化,改善当地生态环境。为此,对绿洲生态环境的建设提出了一些改进措施。This paper summarizes and analyzes almost 40 years＇meteorological data in Hetian Oasis, finding that the oasis microclimate is becoming warm, humid, and the wind speed there is decreasing. This is consistent with the overall climatic change of Xinjiang. As a result, the atmosphere boundary layer elevates, the extent of protection enlarges, feeling heat flux becomes small, latent heat flux grows big and the humidity increases. Because of the change of human activities and natural conditions, the ecological environment has been damaged. But the oasis microclimate changing tendency is advantageous to the optimization, and can improve the local environment. Therefore, the paper proposes some improving measures for the construction of the oasis environment. ecological ecological
