| 摘 要： | 提供了一个描述乌鲁木齐市年、季降水空间分布的估算模型.利用中国气象局整编的气象站点信息资料和位于研究区域的3个站点(乌鲁木齐、达坂城、蔡家湖)从建站到2000年的多年降水资料,采用多元逐步回归方法,分析和估算了3个地理、地形影响因子(即经度、纬度、海拔高度)对乌鲁木齐市降水空间分布的影响,并对回归方程和影响因子进行了显著性检验,得出了一些定性、定量的结果.本文模型估算的降水能够较好地再现该区的实际降水分布,具有一定的适用价值.

| Abstract: | A statistic model for the spatial distribution of precipitation estimation in Urumchi is presented.By using the station information compiled by the National Meteorological Center and the precipitation data of 45 years(1955 to 2000) from three stations in Urumchi,the relations between precipitation and regional geographic and topographic factors such as longitude,latitude,and altitude,is studied with stepwise regression.The results show that the estimated precipitation is highly close to the real distributio... |
