预测甘南天然草场牧草产量的气象模式

The Meteorological Model for Predicting Forage Crop Yield of Natural Grassland in Gannan of Gansu Ptovince

用常规气象资料及牧草资料，按海拔高度的分布、分别分析了甘肃省甘南自治州天然草场不同区域的气象条件与天然牧草产量间的关系，用牧草关键生育期的气温和降水量按海拔高度分区建立产量预报模式，由计算机输出牧草单产分布预报图。

Based on the conventienal meteorological and forage data, this paperanalyses the relationship between meteorological coiiditions in different regions and for-age crop yields of natural grassland in Gannan Autonomous Prefecture of GansuProvince in accordance with the distribution of aItitudes above sea level.The forage cropyield prediction model was established using the temperature and rainfall data during thekey growth and development stage of forage crops in accordance with the aItitudes abovesea level.The distribution predicting maps of forage crop yield per unit area can be out-put by computer.
