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。
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.
