鄂尔多斯高原油蒿灌丛群落生物量和净初级生产力研究(英文)
【摘要】:应用标准株收获法对鄂尔多斯高原油蒿灌丛群落生物量和净初级生产力进行了一个生长季(6月~10月)的研究。结果表明:(1)生长季内不同月份之间相同株型单株油蒿地上和地下生物量差异不显著(p0.1),而地上当年生部分生物量差异显著(p0.01);(2)油蒿群落中,地上和地下总生物量为699.76~1246.40gm-2,年地上部分NPP值为224.09 gm-2y-1;(3)单株油蒿生物量和 NPP 与灌丛体积具有较好的相关性,应用幂指数方程能够达到较好的拟合效果。

Introduction Ordos Plateau is situated in the southern part of Inner Mongolia, Northern China and at the transition between semiarid and arid ecosystems (Li 1990). In the past, this area was known for its fine pastures with ample water and abundant grass
