草地牧草物候发育模型的应用研究——以锡林郭勒草原为例

Application research of grass phenophase models in grassland—A case study from Xilin Gol grassland

摘要: 天然草地牧草生长发育受环境条件影响很大，牧草的发育期年际间和年内有很大变化。利用多年牧草物候观测资料，分析了影响草地牧草生长发育的主要气象要素并建立了锡林郭勒草原主要牧草物候发育模型。

Abstract: The grass growth in natural grassland is affected seriously by environment factors.The developmental period of grass is very different in every year.A long-term observation data of grass and main climate data in natural grassland are analyzed.The phenophase models of four species are built in the grassland.
