石羊河流域气候暖湿化变化特征分析
Analysis of climate change towards warming-wetting trend in Shiyang River Basin
摘要
Abstract
Based on data on air temperature, precipitation, and the drought index of the Shiyang River Basin over the last 47 years, the warming-wetting trend in this basin was analyzed. The results show the following: (1) The average temperature of the Shiyang River Basin showed an escalating trend at 0.32℃ per ten years over the last 47 years. During the period from the 1960s to the 1980s, the seasonal average temperature showed an insignificantly escalating trend and the annual average temperature showed a negative anomaly. During the period from the late 1990s to the early 21st century, the seasonal average temperature showed an increasing trend, which was evident in winter, and the temperature anomaly increased from -1.04℃ to 1.87℃. (2) The precipitation showed an overall ascendant trend, but the rising trend was not significant; the precipitation increased by 7.1 mm per ten years, which was consistent with the increasing trend of the precipitation in the northwestern area. (3) The annual average drought index decreased on the whole, but the decreasing trend was not significant; the reduction rate was -0.98 per ten years. (4) Through the Mann-Kendall test, it was found that the temperature increased abruptly in 1994, the precipitation did not change abruptly, and the drought index decreased abruptly in 1992 and 1993. This study shows that the climate in the Shiyang River Basin is becoming warm and humid, which will facilitate oasis development and economic development in this area.关键词
