摘要：

In this paper, spatial and temporal patterns of changes in extreme temperature are investigated by using 15 extreme temperature indices based on 32 meteorological stations data for the period 1960-2009 in Haihe River basin, with the help of simple linear regression method, Mann-Kendall trend test and GIS technique. Results show that all temperature extreme indices present significant change expect TXx with a non-significant positive trend in the Haihe basin. In almost whole basin, FD, ID, TN10p, TX10p, CSDI and DTR displayed significant negative trend. While SU25, GSL, TMAXmean, TMINmean, TNn, TN90p, TX90p and WSDI exhibited significant positive trend. The slopes for indices related to low temperature are larger than that of indices related to high temperature. Furthermore, the trends for TN90p, TX90p and WSDI were respectively almost opposite to TN10p, TX10p and CSDI in the Haihe River basin. (C) 2012 Published by Elsevier Ltd.
