Abstract

本文利用1960~2011 年黄土高原及其周边77 个气象台站逐日降水资料,采用SPSS、GIS 空间分析和转移矩
阵,分析黄土高原地区年均降水量变异特征,多年及各年代平均降水量时空分布特征。结果表明:黄土高原地区年
降水量空间变异性和时间变异性较大。区域内多年及各年代平均降水量呈现从东南向西北减少的空间趋势。区域内
年降水量整体呈减少趋势,但在2000 年之后略有回升。在1960~2011 年间平均降水量<200 mm/a 和200~400 mm/a
的区域面积扩大,平均降水量在400~800 mm/a 和>800 mm/a 的区域面积缩小。平均降水量<200 mm/a 的区域在西北
地区有扩张趋势,平均降水量200~400 mm/a 的区域在区域中部扩张,平均降水量在400~800mm/a 和>800 mm/a 的区
域在区域南部呈缩减趋势。

Other Abstract

This paper used daily precipitation data of 77 stations in Loess Plateau and its neighbors from 1960 to 2011. This
study analyzed variation characteristics of annual precipitation, spatial distribution of average precipitation and
spatial-temporal characteristics of each decade’s precipitation in Loess Plateau through SPSS19, GIS spatial interpolation and
transition matrix. Results showed that temporal and spatial variability of annual precipitation was obvious. The average
precipitation of whole period and four decades showed a tendency that precipitation decreased from southeast to northwest.
Annual precipitation showed a decreasing trend from 1960-2011, but it became to increase since 2000. The area of annual
precipitation that less than 200 mm/a and between 200 and 400 mm/a had increased, and the area that larger than 400 mm/a
had reduced. The area of precipitation that less than 200 mm/a extended in the northwest; the area of precipitation that
between 200 and 400 mm/a extended in the central; the area of precipitation that larger than 400 mm/a narrowed in the south.
