| 摘 要： | 对环湖地区高寒草原进行围栏封育,采用样方法对植物群落地上生物量及其生长速率进行了分析研究,以探明植物群落地上生物量的生长规律。结果表明：在牧草整个生长季,地上生物量的变化呈单峰型,且峰值出现在8月上旬,为267.1g/m^2;群落的BI、ABI、AGR、RGR、AAGR和ARGR季节变化动态也呈单峰型,与地上生物量的季...

| Abstract: | Based on fenced enclosure in the alpine grassland area in around Qinghai lake,in order to study growth characteristic of aboveground biomass of plant communities,aboveground biomass of plant communities and their growth rate were studied and analyzed in the sampling ways.The results showed that: the change of aboveground biomass presented a curve of single peak throughout growing season.Peak value was presented in the first half of August,and it was 267.1 g/m2.The seasonal dynamic change of the community's ... |
