采用历史气象资料分析和参与性农户评估相结合的方法,对阿拉善荒漠区气候变化特征进行分析,并抽样研究了荒漠区牧户家庭基本状况与经营现状、牧户家庭对气候变化及其影响的感知与应对策略。结果表明,近50年阿拉善左旗和阿拉善右旗年气温呈极显著上升趋势,但年降水量总体趋势仅在波动中微弱增加。牧户对温度升高的感知与事实基本相符。牧户感知草地生态环境认为近10年草地生产力和草地植物种类已经减少;土壤沙化、草地鼠虫害和地表水减少程度增加。极端气候事件在近10年中频发,并对家畜健康和生产、草地牧草生长产生极大影响。受气候变化影响,在畜牧业生产中牧户采取主要措施是在秋季储备充足草料备用,同时结合圈养方式维持生产。未来气候变化还将持续影响牧区人民的生产生活,建议采取合理的应对措施增强荒漠区牧户对气候变化的适应能力。
