| 摘 要： | 通过对鄂尔多斯草原短花针茅(Stipa breviflora)的大范围对比观测试验,得出针茅的旬生长高度与旬平均气温和旬降水量相关密切。针茅本旬生长高度与上一旬的生长高度相关系数高达0.957,得出针茅的生长符合线性生长规律。因此分析建立了多元线性回归模型和生长高度预测模型。经拟合检验效果较好,预测模型能在一定精度水平上准确地预测针茅的生长高度。

| Abstract: | Through to Stipa breviflora wide range observation study in the Erdos grassland, the result indicated that, Stipa breviflora growth highly on a ten-day period correlated closely with a ten-day period average temperature and a ten-day period precipitation. The correlation coefficient of Stipa breviflora growth height on ten-day period with previous on ten-day period was 0.957, which obtained the growth of Stipa breviflora according with the linear growth rule. Therefore we had established the multiple linear regression model and growth height the forecast model, which was good by test, and these forecast models could forecast the growth heigh of Stipa breviflora accurately in certain precision level. |
