| 摘 要： | 采用联合国粮农组织最新推荐的模型方法(FAO56),参照毗邻地区的灌溉试验成果和当地群众的灌水经验.对渭干河--库车河三角洲绿洲冬小麦、夏玉米和棉花等作物不同生育期的需水量及需水规律进行了分析.结果表明:①作物各生育期需水量的多少,取决于生育期的长短和需水强度;②作物需水量自西向东、自南向北增加,其空间波动与气温、风速和湿度息息相关;③若根据目前渭干河一库车河三角洲绿洲农业用水所占总水量的实际比例计算,地表水供给量完全满足作物对需水的要求.如果按国际上发展经济用水占河流总水量的比例计算,河道有效来水量只能满足作物的需水要求.若要全部考虑城镇工业用水、生活用水及农业用水,加上地表水资源的利用率较低、季节变化大,则不能完全满足作物灌溉用水,导致挤占生态用水.

| Abstract: | In this study,the water-demanding volumes and mechanisms of water use by primary crops in the Organ River-Kuqa River delta oasis in Xinjiang,which include winter wheat,summer corn and cotton,were analyzed during different growth stages using the new model recommended by the Food and Agriculture Organization of the United Nations(FAO56).This study was conducted using the results of irrigation experiments conducted in adjacent areas and reports by local residents.The results of the study were as follows:(1) T... |
