摘要
通过研究相关统计资料对新疆农田化肥投入在时间和空间上的变化进行了分析。结果表明：1980年以来新疆农田投入化肥分为稳步上升、快速增长和徘徊波动三个阶段。新疆农田投入化肥在空间上的变化为：地区间分布不平衡,南疆与北疆、棉区与粮区、兵团与地方之间差异明显。在此基础上对未来新疆化肥资源的施用趋势进行了讨论。
Based on official statistical data covering 1980 to 2003, the spatial-temporal change of the chemical fertilizers inputting of Xinjiang are illustrated in detail. The application of chemical fertilizers are divided asthree phases of the steady increasing phase, the high speed phase and the fluctuating phase. The farmland applying fertilizer is transforming from the former extensive management stage to intensive management stage at present. The paper found out that chemical fertilizer resources are distributed unbalanced in different counties in Xinjiang. The economic efficiency is the determining factor to influence chemical fertilizer inputting of farmers and the agricultural policy, the structure of crop production, the agricultural production level and the quality of working conditions also have huge influence to the chemical fertilizer inputting. Finally the perspectives of the application of chemical fertilizers in Xinjiang show that the demand of chemical fertilizer will rise continuously, the phosphate fertilizer increase speed will be dropping and potassium fertilizer ratio will have an accelerating upward tendency.
