| 摘 要： | 以兰州南北两山集雨绿化无灌溉人工生态系统为研究对象，在定位监测的基础上，运用生态水文学的基本原理，分析了拧条和柽柳土壤水分的土层分配、利用和水量平衡模式的变化，讨论了集雨区的植被盖度和结皮的发育成因和影响，以及拧条和柽柳在不同集雨面积的蒸散发量。得出在兰州南北两山集雨绿化可以推广乔木柽柳，其生态系统和生态水文过程比较稳定。

| Abstract: | Taking the manual ecological system of rainfall collecting for tree planting in the mountains adjacent to Lanzhou city as research object, based on fixed field observation, using basic principle of eco-hydrology, this paper analyzed the variation of water balance mode, distribution and utilization of soil water in different soil layer of Tamarix.ramosissima and corshinskii Lam, discussed the vegetation coverage, formation reason and influence of soil crust in rainfall collecting district, and of Tamarix.ramosissima and corshinskii Lam in different rainfall collecting area. In the end, the author got the conclusion that Tamarix.ramosissima and corshinskii Lam could be spread in the district of rainfall collecting for tree planting in the mountains adjacent to Lanzhou city for its steady ecology and eco-hydrological process. |
