甘肃省中西部地区人工牧草产量与气候因子关系研究

Study on the Relationship Between Weather Factors and Yield of Artificial Pasture in Mid and West Region of Gansu

根据试验观测资料,分析了气象因素和产量的动态,运用统计学原理分别建立了人工牧草产量与各环境因子及多因子回归模型,采用最优化原理期望值系数法对影响人工牧草的环境因子进行相关分析,并利用水-热指数建立人工牧草产量积累的农业气象模式。

Based on the observation data, the dynamics of the environmental factors and grass yield were analyzed, in addition the regression model between the yield of artificial grass and all sorts of environmental elements and multiple factors was established with statistics theory. By the way of expected value＇s coefficient of optimization principle, the environmental factors which influenced the artificial grass were analyzed. Moreover, agrometeorological model of yield accumulation of artificial pasture was established aecording to the heat -water indices.
