摘    要:目的]探究锡林郭勒盟地区不同草地类型生物量年际变化与降雨量的关系。方法]基于CASA模型,利用2009~2013年气象数据与FPAR遥感数据,对锡林郭勒盟地区生物量年际变化规律及其与降雨量的关系进行分析。结果]2012年的生物量处于最高,草句草原的生物量在2013年处于最高水平,其他草地类型的生物量在2012年均居最高。植被生物量随年度变化波动趋势与降雨量变化一致。结论]2009~2013年锡林郭勒盟地区不同草地类型生物量年际变化幅度不尽相同,降雨量是影响其变化的重要因子之一。

关 键 词:CASS模型  生物量  降雨量

Abstract: Objective] The aim was to study the relationship between annual variations of biomass of different grassland types in Xilinguole area and precipitation. Method] Based on the CASA model, the relationship between annual variations of biomass of different grassland types in Xilinguole area and precipitation were analyzed by using meteorological data and FPAR remote sensing data. Result] The biomass was the highest in 2012. The biomass of meadow steppe was the highest in 2013, and the other types of grassland were the highest in 2012. The change regulation was coincident between vegetation biomass and the precipitation. Conclusion ] The annual variations of biomass of different grassland types in Xilinguole area were different, and precipitation was one of important influencing factors.
Keywords:CASS model  Biomass  Precipitation
