草原干旱对天然牧草生长发育及产量形成的影响

天然牧草是放牧畜牧业的主要物质基础,其生长动态和产量形成受气象条 件的影响和制约,特别是水分条件在很大程度上决定着植物的地理分布和生物生产力水平。 根据降水量及土壤水分条件与天然牧草生长动态及产量的关系,建立了天然牧草生长高度动 态模式和草原初级气候生产力模式,以便为进一步研究草原干旱的气候指标提供理论依据。
Impacts of Grassland Drought on the Growth and Yield of N atural Grass
 By analyzing the relationships among the growth dynamics and yield of na tural grass and precipitation as well as soil water content,calculation models w ere established to estimate the growth height and primary production of natural grass on typical grassland of Inner Mongolia.
