摘要
文章应用In VEST模型,运用生境质量指数、生境稀缺度指数和生境退化指数反映三江源的物种多样性的状况,并由此评价三江源生态环境质量,是对区域生物多样性价值评估的有益探索。研究结果表明,2000-2010年期间三江源地区野生动植物栖息地的生境质量在多数区域处于较好水平,整体质量变化不明显,区域质量指数均值为0.6左右,2010年比2000年升高了0.27%,有微量上升。其中自然保护区所涉及的治多县、杂多县、唐古拉山乡的生境质量有所改善,也反映了近年来三江源地区自然保护区生态恢复与建设的成效。
This paper uses In VEST model to reflect the status of the species diversity in Sanjiangyuan by the ecological quality index,ecological scarce index and ecological degradation index soa as to evaluate the ecological environment quality of Sanjiangyuan. It is a useful exploration for the value evaluation of regional biodiversity. The results of the study indicate that from 2000 to 2010, the ecological quality of the wildlife habitat in Sanjiangyuan is in a better level. The changes of the overall quality are not obvious. The mean value of regional quality index is about 0.6, the ecological quality in 2010 increased 0.27 percentage points than 2000 year, there is a trace of rising. The natural reserves involved in Zhiduo County, Zaduo County and Tanggulashan Town, the habitat quality of which has improved. It also reflects the effect of ecological restoration in Sanjiangyuan nature reserve in recent years.
