| 摘 要： | 研究了围栏封育对环湖地区高寒草原植物群落地上生物量的影响,结果表明：在牧草的整个生长季,总生物量呈单峰曲线变化,生育初期地上生物量最小,到8月上旬生物量达到最大,为267.1g/m2。围栏封育有利于优良牧草（禾草＋莎草）的生长,提高优良牧草的百分比组成;抑制阔叶草（豆科＋杂草）的生长,降低其百分比组成。

| Abstract: | The effect of fencing-endosure on aboveground biomass of plant comunities for alpine-cold grassland around the region of Qinghai lake.The results showed that the change of total biomass showed a single peak curve in the whole growing season of grass.The aboveground biomass was minimum during the initial growth and was the maximum in the first ten-day period of August which was 267.1g/m2.The fencing-endosure conduced to growth of good forage(grasses and sedges)and increase the percentage of good forage,and s... |
