| 摘 要： | 对河西山地－绿洲－荒漠农业生态系统运行机制的研究结果表明：绿洲中的科技容量和生产能力比荒漠高出几倍乃至几百倍，绿洲农业生态系统的格局和效益趋于合理与完善。为确保绿洲子系统的稳定和持续发展，有赖于南部山地子系统的水源涵养及物种保护，也有赖于北部荒漠于系统稳定的“屏障”作用。

| Abstract: | The running mechanism of famous mountain-oasis-desert agro- ecosystem in Hexi was approched. The results showed that the scientific capacities and productive abilities of oasis were as many times,evenhundreds times as those of desert,the patterns and effects of oasis system trended to be reasonable andperfectly. To ensure the stable and sustained of oasis sub- system depended not only on water conservationand diversity of mountain sub- system.but also on stability of northern desert sub- system and its sheltereffect. |
