| 摘 要： | 以六盘山自然保护区的植被为研究对象,根据分布在林区的泾源、六盘山、原州区、西吉等台站的气象数据为依据,研究了1971～2008年六盘山自然保护区植被变化与气候变化之间的关系。结果表明,近38年来保护区内的六盘山降水大于南北区,南区远大于北区;近十几年降水有减少趋势。保护区内的六盘山气温低于南北区,南区低于北区;各区温度有很强的振荡一致性,近于同时上升下降;1984年以后,各区气温呈明显上升趋势,峰值和谷值全部上升,并在近10年有加快迹象;温差有增大趋势。保护区内的六盘山湿度大于南北区,南区大于北区;三区湿度的变化方基本一致,1989以后湿度迅速下降,尤其以北区最显著,六盘山与南北区、北区与南区的湿度差值有增加趋势,尤其是六盘山与南北区之间。周期分析表明,影响六盘山自然保护区的大气环流形势存在3年左右、8年左右、11年左右、15年左右的周期,主观分析异常强迫得到的周期与此一致或接近。在降水减少、气温升高、湿度下降等不利于天然植被正常生长的大背景下,六盘山自然保护区植被面积仍然在增加。

| Abstract: | According to the climatic data in Jingyuan,Liupanshan,Yuanzhou District and XiJi,the relationship between the change of vegetation coverage and climate in Liupan Mountain nature reserve during 1971-2008 was studied.As indicated by the results,the precipitation in Liupan Mountain was larger than that in the south and north area of nature reserve,and that in south was larger than that in north,the precipitation was declining.The temperature of the north and south area was lower than that in Liupan Mountain,an... |
