| Abstract: | 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 according to the heat-water indices. |
| Keywords: | mid and west region of Gansu artificial pasture yield weather factors water-heat indices |
