| 摘 要： | 本文通过海北牧业气象试验站1997~2004年牧草生物量测定资料,分析了环湖天然草原生物量动态变化。结果表明:分种牧草生物量年变化幅度大于牧草群体的变化;牧草生长季5种主要优势种牧草的生物量占总生物量的50%以上;牧草群体生物量年变幅范围在191.8~238.2g/m2之间。

| Abstract: | Natural steppe biomass dynamic variety is analyzed in this paper for around region lake of qinghai, based on herd the grass biomass prognosticates the data in 1997 - 2004 years of Haibei animal metorological experiment station. The result shows that constitute the plants community of the main dominant species forage biomass variety of year range is bigger than community. At herd the grass growth season, 5 kinds of main dominant species forage biomass is 50% that total forage biomass; the community biomass year change scope is 191.8 -238.2 g/m^2. |
