These imply that the spatial distributions of the different grades of the arable land , classified by the reference land unit method , reflect reasonably the spatial changes of geomorphological units and soil types . the linear estimation model between comparable productions and the corresponding quality ratings of 210 sample units shows that the coefficient of determination r2 is 0 . 876 , which means that 87 . 6 % of the change of y is explained by the change of x . it is concluded that the arable land quality ratings calcul ated by the method can reflect the biologic productivities of land
另外，利用210个样点单元的标准粮产量( y )与其对应样地法土地质量分( x )进行线性拟合，判定系数r ~ 2等于0 . 876的含义是指y的变异中有87 . 6是由x引起，表明了样地法土地质量分的高低较好地反映了耕地的生物生产力水平。

In statistics, the coefficient of determination, denoted R2, is used in the context of statistical models whose main purpose is the prediction of future outcomes on the basis of other related information. R2 is most often seen as a number between 0 and 1.
