中文摘要	利用塔克拉玛干沙漠腹地塔中气象站和周边北缘、南缘、东缘3个气象观测站2000 - 2014年的气象观测资料,分析沙漠腹地降水和风沙环境特征并与同期周边地区作对比分析。结果表明: 沙漠腹地逐年平均降水量为26.0mm,整体年平均降水量比周边偏少了37.3%,夏季降水最多,为全年的69.3%,冬季最少,仅为全年的3.4%,各季节平均降水量均小于周边平均值,月降水比周边偏少51.9%; 通过变差系数说明沙漠腹地夏季降水量和水汽压比周边地区更稳定; 沙漠腹地主要以NNE、NE、ENE和E四个方向风为主,风向更集中; 沙漠腹地平均风速为2.10m/s,比周边各站都偏大,和周边各站的风速分布呈现了较好的一致性; 沙漠腹地大风日数和年沙尘暴日数较稳定,轮台地区大风日数年际波动最大,且末年沙尘暴发生日数变化最显著。
英文摘要	The meteorological data during 2000 and 2014 from 4 meteorological stations including Tazhong meteorological station in the hinterland of Taklamakan desert and other 3 stations distributed in the adjacent regions were used to analyze the characteristics of precipitation and wind - blown sand environment,and was compared them with the surrounding areas in the same period. The results showed as follows: the annual precipitation in the inner Taklamakan desert was 26.0mm,about 37.3% less than the surrounding areas; summer precipitation was the most,accounting for 69.3% of annual precipitation; winter precipitation was the minimum,only accounting for 3.4% of the total year. the average rainfall of every season was less than the surrounding areas,and the average monthly total precipitation was 51.9% less than the surrounding areas. Coefficient of variation indicating that the summer precipitation and water vapor pressure in hinterland of desert were more stable than the surrounding area. The wind inside the desert was mainly in NNE,NE,ENE,and E,and was more concentrated; the average wind speed inside the desert was 2.10m/s,and bigger than the surrounding stations; the sandstorm and strong wind days in hinterland desert were less fluctuated; the strong wind days in Luntai were the most fluctuated and the sandstorm and strong wind days in Qiemo were the most fluctuated.
