【摘要】 根据鄂尔多斯市及其周边地区 2 4个站点 30年气象资料 ,在对已有的水文、气象站网 (均为非规则分布 )进行正则化基础上 ,对ET0 空间结构性进行了系统分析。充分利用ET0 区域信息的特征 ,采用Kriging无偏最优估计方法对区域信息进行最优估计 ,并据此绘制了参考作物ET0 最优等值线图。用以了解鄂尔多斯市的作物需水量的分布规律 ,为发展牧草提供科学的依据 ,提高畜牧业的生产总值更多还原

【Abstract】 Based on regularization of hydrographic and metrological station net （all irregular station net）and the 30 years meteorological data of 24 stations in Erdos and circum zone,ET₀ spatial structure was analyzed. The region information was estimated optimally with Kriging unbiased optimum estimating way,and the optimum constant value line for reference crop ET₀ drawn. The drawing provided the distribution rule of crop water requirement in Erdos and scientific basis for developing pasture and increasing livestock production.更多还原
