摘要:
位于青藏高原向四川盆地过渡地带的甘孜藏族自治州,分布有大面积的国家自然保护区和海洋性冰川,了解和分析该区域气候变化的时空趋势,对规划该地区旅游发展、环境保护和生态文明建设具有特别重要的意义。根据1961-2015年甘孜州11个站点的气温和降水数据,采用线性回归、距平分析、滑动平均、Mann-Kendall突变检验及样条函数插值的方法,对甘孜州55年气温和降水的时空变化进行研究。研究表明:甘孜州全年和各季气温都呈现显著上升趋势,全年气温变化倾向率为0.242 ℃/10 a,春、夏、秋、冬气温倾向率分别为0.176 ℃/10 a、0.211 ℃/10 a、0.211 ℃/10 a、0.368 ℃/10 a,冬季气温的增加最为显著。气温倾向率在区内空间差异很大,随着海拔升高,增温速率增大。甘孜州的降水总体虽递增,但增加的趋势并不显著,全年降水倾向率为11.22 mm/10 a,各季降水倾向率分别为5.23 mm/10 a、4.15 mm/10 a、1.68 mm/10 a、0.22 mm/10 a,春、夏季降水的增加对于年降水贡献最大。降水倾向率在空间上呈现由东向西逐渐减小的趋势,在西南边缘地区降水甚至出现负增长。总体而言,甘孜州气候有向暖湿化发展的态势,这种趋势在高海拔地区表现得更为明显。
Abstract:
Ganzi is situated in the transition zone between the Qinghai-Tibetan Plateau and the Sichuan Basin with a large areas of national nature reserves and marine glaciers. Analyzing the temporal and spatial trends of regional climate change is of special significance for planning tourism development, environmental protection and ecological civilization construction in the region. Based on the temperature and precipitation data from 11 sites in Ganzi during 1961 to 2015, methods of linear regression, anomaly analysis, moving average, Mann-Kendall mutation test, and spline interpolation were applied to analyze spatial and temporal characteristic of temperature and precipitation in Ganzi. The study showed that: Ganzi had a significant upward trend in the annual and seasonal temperatures, with a temperature change rate of 0.242 ℃/10 a for the whole year and 0.176 ℃/10 a、0.211 ℃/10 a、0.211 ℃/10 a、0.368 ℃/10 a for the spring, summer, autumn and winter temperatures respectively. The increase in winter temperature contributed most to the increase in annual average temperature. Spatial distribution of annual and seasonal temperature variation varied greatly in the area. With the increase of altitude, the rate of warming increased. Although the precipitation in Ganzi Prefecture was generally increasing, the trend was not significant. The annual precipitation increased at a rate of 11.22 mm/10 a, and the seasonal precipitation increased at a rate of 5.23 mm/10 a, 4.15 mm/10 a, 1.68 mm/10 a, and 0.22 mm/10 a respectively. The increase of precipitation in spring and summer contributed the most to annual precipitation. Annual precipitation tended to decrease from east to west in space, and precipitation may even decrease in the southwestern margin. In general, there is a warming and wetting trend of the climate in Ganzi, and this trend is more pronounced in high altitude areas.
