| 中文摘要: |
| 本文分析了人工绿洲发展的特点及我国干旱内陆河区绿洲稳定性要素，按各要素对绿洲稳定性贡献，划分出绿洲绿色生态系统和绿洲灰色生态系统，并指出农田更具有灰色生态系统的成分。通过对比分析绿洲景观及与其相应的水热平衡关系，提出评价现代经济意义下绿洲稳定性及其开发利用方向的绿洲绿色指数和计算方法。通过绿洲绿色指数，可以快速诊断绿洲宏观水资源开发利用问题，设计绿洲适宜的发展规模。 |
| 英文摘要: |
| The characteristics and the main factors affecting the stability of the oasis in arid region of China are analyzed. The ecosystems of oasis are classified into green ecosystem and grey ecosystem according to their contribution to the stability of oasis. Based on the comparison of landscape effect and its relevant water-energy budget, an index for assessing the stability of oasis is proposed and corresponding calculation method is established. The index can be used to judge the utilization degree of water resources and to determine the sustainable scale and development pattern of the oasis. |
