摘要:
气候生产潜力反映了植被群落在自然条件下的最高生物学产量,可作为草地生产力评价依据。本文依托1961-2013年祁连山区17个气象站数据,利用Thornthwaite Memorial模型以及MK检验、EOF分析方法,对研究区域夏季(5-9月)草地生产力进行了评价。结果显示祁连山降水倾向率为1.0552 mm·a-1,温度倾向率0.0357 ℃·a-1,气候变化呈暖湿型特征,其中降水是影响祁连山草地生产力的主要因素。第一特征量以托勒—野牛沟—肃南为高值区,草地生产力显著优于其他区域,应该作为祁连山草地重要保护区域。在气候驱动上,降水对祁连山草地生产力的影响要远远大于温度,尤其在沿沙区和戈壁荒漠区; 而温度的影响显著体现在湿润地带即祁连山高地一带。该研究为祁连山草地保护与发展提出了参考依据。
