【摘要】 选取同一时间断面，对影响梯田产量的各种因索迸行分级、分别管理，对产量迸行实割实测，单收单打。采取多元线性回归方法进行计算，得出梯田产量与各影响因子的回归模型。结果表明，在内蒙古半干旱地区，同等降水条件下，影响梯田产量的因素主要是管理水平和土壤肥力条件。更多还原

【Abstract】 Choosing the same time section,grading the various factors by effecting on the terraced field yields, managing them respectively, havesting the crops and measuring the yields individually in practice We have obtained a regression model between the terraced field yield and its effecting factors by using the multiple variabls rinear regression method.The results show that the effecting factors on the terraced field yields are mainly the management levels and the condition of the soil fertility in inner Mogolian semidrought region under the condition of the same rainfall.更多还原
