| 摘 要： | 区域生态系统服务功能的稳定性是评价其生态功能的重要指标之一。构建了区域生态系统服务功能稳定度指数评价模型,并对中国1998～2004年间区域生态系统生产能力进行评价,发现中国各区域生态系统的生态稳定度指数在空间上差异巨大。造成这种差异的原因主要是生态系统的人化程度。从区域生态系统服务于功能稳定度看,西北内陆区由于气候干燥,生态系统的生产能力十分有限,呈现出低水平的稳定。 |
| 关 键 词： | 平衡 波动 服务 功能稳定度指数 |

| Abstract: | The eco-system service function stability is one of the most important aspect to access the ecosystem functions. The eco-system service function stability index model is designed in this paper. Vegetation data is used to access China regional productivity index from 1998 to 2004. It is found that the eco-system service function stability is obviously distinct in different area. Eecosystems influenced by human being are more unstable and vulnerable. From the view of eco-system service function stability, the stability in the northwest inland is weak due to less productivity. |
| Keywords: | Balance Fluctuation Eco-system service function stability index |
