中文摘要:本研究在实验室条件下,用传统的微生物培养法,选择重金属离子Pb2+在水培条件下对大薸和穗状狐尾藻进行胁迫培养,通过测定大薸和穗状狐尾藻根系的微生物区系及与氮循环有关的四种细菌的数量变化发现:细菌、真菌、放线菌对重金属Pb2+的不同浓度的敏感性不同;重金属Pb2+胁迫对氨化、硝化、亚硝化和反硝化四类细菌的影响也表现出各自的特殊性。

Combining the available regional geological and geophysical research, the petrogenesis of the magmatism was studied. As a response and absorption to the IndiaAsia collision, the northeastward flow of the asthenosphere beneath the Tibetan Plateau along the 400 km depth interface was blocked by the North China craton, and caused a systemic sequences in West Qinling Region, including the strikeslip fault systems and pullapart basins in the shallow crust and the origin of the twotype magmatism in this work in deep lithosphere. This explanation is consistent with the lithology and plumelike geochemical features of the kamafugite and potassic trachybasalt, which are significantly different from the potassic magmatism within the plateau and its adjacent regions.
