毛乌素沙区的气候变化及人为活动特征分析

本文利用毛乌素沙区１０个气象站近３０年的气象资料和国民经济经统计资料，分析了该区的气候变化特征和人为活动特点，研究结果表明，该区３０多年来气温抬升、降水量下降、但降水稳定性增强、平均风速减少；实现农牧业生产由粗放经营向集约化经营转变，提高该区综合生产能力，是防止农业生态环境进一步退化的重要措施。

ANALYSIS ON CHARACTERISTICS OF CLIMATIC VARIATION AND ARTIFICIAL ACTIONS IN MO US SANDY LAND

Characteristics of climatic variation and artificial action at Mo Us sandy land are analysed in this paper by using statistic data of climate and national economy about 30 years often climatological stations. Research results show over years, temperature has gone up,precipitation has gone down, but precipitation stability has strengthened, average windspeed has descreased. Agriculture and animal husbandry have been translated from extensive farming into intensive farming, and increasing synthetical production capacity are mainmeasure to prevent agricultural ecological environment from degeneration.
