摘要
依据喀什地区1981—2010年气象日数据资料,利用常用的统计方法和降水量相对变率,研究了喀什地区1981—2010年的年内降水量变化、降水量年内分配情况、季节变化以及降水量相对稳定性。结果表明:喀什地区降水量年内分配不均匀,降水量主要集中在6、7、8月,10月—翌年4月降水量偏少。喀什地区降水量空间分布不均匀,累年平均月降水量为4.8 mm(麦盖提)~6.8 mm(英吉沙)之间。降水量的季节分配具有同步性,主要集中在春季和夏季。近30年来,喀什地区降水量相对变率基本一致,其中喀什地区叶城县降水量年际稳定性较差,水资源利用率较低。
Based on the daily meteorological data in Kashgar from 1981 to 2010,the common statistical methods and relative variability of precipitation were used to study the variation of annual precipitation in Kashgar from 1981 to 2010, the distribution of precipitation within a year, seasonal changes, and precipitation. relative stability.The results showed that the precipitation in Kashgar was unevenly distributed throughout the year, and the precipitation was mainly concentrated in June, July, August, October and April of the following year. The spatial distribution of precipitation in Kashgar was uneven, and the average monthly precipitation over the years was between 4.8mm(Maigaiti) and 6.8 mm(Yingjisha). The seasonal distribution of precipitation was synchronous, mainly in spring and summer.In the past 30 years, the relative variability of precipitation in Kashgar was basically the same. Among them, the inter-annual stability of precipitation in Yecheng county in Kashgar was relatively poor, and the value of water resources utilization was relatively low.
