| 摘 要： | 对我国西北地区干旱草地进行了广泛的调研,引种,驯化和成功繁育了国内外30余种适于西北地区干旱环境栽培的耐旱牧草,并对旱生、超旱生牧草的生态型进行了量化界定的基础上,根据地理位置、水热资源、植物群落、土壤类型及地表基质等4项指标,将我国西北干旱草地划分确定为高原、盆地极旱荒漠草地生态区;黄土高原干旱、半干旱草地生态区;青藏高原、黄土高原农牧交错带草地生态区和人工草地生态区,及各干旱草地生态区宜栽牧草。

| Abstract: | Aridy grassland in Northwest China were divided into four ecological areas according to geographical position,water and warm resources,plants community and soil type,which included extremely drought desert grassland in plateau and basin,arid and semiarid grassland on the Loess plateau,interlaced belt between a farming area and a pasturing area on the Qinghai-Tibet plateau and Loess plateau,artificial grassland.The ecological type of xerophytic and extra-xerophytic forage were quantified and defined as well.The theory that couple position between the ecologicalareafor drought grassland and ecological type of pasture for drought tolerance was put forward,which play a certain referenced role in ecological and environmental construction for West Development Project. |
