- Abstract:
-
By using of linear trend and moving average analysis methods and GIS spatial analysis technique, the long-term trend of temperature and precipitation and the distibution were analyzed in this paper. The data used in this paper were observed at 38 meteorological stations. The results show that the annual mean precipitation exhibited a decreasing trend while the annual mean temperature exhibited an increasing trend during the past 40 years in Haihe River basin. The annual variation of precipitation was obvious, the annual maximum and minimum proportion of precipitation was 2.31 and the variation coefficient of it was 0.18; while the annual variation of temperature was not clear, the annual maximum and minimum proportion of it was only 1.32 and the variation coefficient was 0.06. The reginal differences were obvious and the trend was that the precipitation decreased from the windward slope of Taihang Moutain and Yanshan Moutain to northwest and southeast of the basin while the temperature decreased from southeast to northwest.
