该文以物种组成较为复杂的青藏高原东部亚高寒草甸为背景,结合最新的群落中性理论,以解释亚高寒草甸草本植物群落的物种分布格局和生物多样性的维持机制。
Backed by the large-size Dachang Gold Deposit, the authors made a preliminary study of the supergene process in the western part of the cold and high meadow area in Qinghai Province.
依托大场大型金矿床对青海省高寒草甸区西部的表生地球化学作用进行了研究,发现风成沙集中在-40～+160目粒级段,富含SiO2,而绝大多数元素的含量均很低;-20目残坡积土和-5～+20目草皮层土富集或基本富集了大部分金矿化指示元素,均可代表近源物质。
Continuous field experiment was carried out on alpine meadow along different elevation gradient in Qilian Mountains during the growing season of 2004 using a soil respiration chamber(Li-6400-09) connected to a portable photosynthesis system(Li-6400).
采用Li-6400便携式光合作用测量系统连接Li-6400-09土壤呼吸室,在2004年生长季节对祁连山高山草甸土壤CO2通量沿海拔梯度进行了野外定位试验,统计分析了水热因子及根系生物量对高山草甸土壤CO2通量特征的可能影响。
),which is covered with alpine meadow,located in the middle reaches of the upper Heihe River,one of the long inland river in Northwest China.
2005年9月—2006年9月,具有较高代表性的3个山坡径流场均没有观测到产流量,结合蒸散发观测和野外调查,发现夏季高山草甸具有明显的地表径流拦蓄和水源涵养作用。
The results showed that in 0-10 cm soil layer,the biomass,length density,surface area density,and volume density of living fine roots were all decreased in the order of evergreen broadleaf forest<dwarf forest<coniferous forest<alpine meadows,with significant differences(P<0.
结果表明:0~10 cm土壤活细根生物量、活细根根长密度、活细根表面积密度、活细根体积密度均是常绿阔叶林<矮林<针叶林<高山草甸,各群落间呈现极显著差异(P<0。
