气候变化对红枣生产环节的影响分析

Analysis on Impact of Climate Change on Production Processes of Red Jujube

在探讨气候变化对当地红枣生产造成影响的基础上,分析了红枣种植户应对气候变化的适应性行为。结果表明,2007—2014年,224团的年平均温度和年降水量呈反向变化趋势。近8年来,224团气温以0.9℃/8年的趋势降低,变化趋势较为缓和;年总降水量呈显著增加趋势,变化波幅较大,波幅为102.4 mm;气候变化对红枣生产的影响主要是对品质、产量及病虫害方面;目前红枣种植户对气候变化的适应性行为以事后补救为主。

Abstract Based on exploring the impact of climate change on local red dates production, the adaptive behaviors of jujube cultivation households to climate change were elaborated. The results showed that the annual average temperature and annual precipitation in 224 groups＂ area in 2007-2014 had a reverse trend. Over the past eight years, the temperature of the area redueed with 0.9℃/8 years trend, and the trend was more moderate. Annual total precipitation showed a significant increase trend, with a change in volatility （102.4mm）. The mainly effects of climate change on jujube production were quality, yield and pest and disease. At present, the adaptation behavior of jujube farmers to climate change was mainly remedied afterwards. Key words Climate change; Meteorological disasters; Adaptive behavior
