| 中文摘要 | 甘南黄河重要水源补给生态功能区地处青藏高原的东北边缘,土地总面积为3.06*10~6hm~2,是干旱区生态环境变化的敏感地区.该区曾被誉为"黄河蓄水池"的玛曲湿地趋于干涸,生态环境十分脆弱.在分析甘南黄河重要水源补给生态功能区的生态现状的基础上,依据有关生态脆弱性评价方法,结合天然草地分布的实际状况,建立生态脆弱性评价体系,对该区的草地生态环境进行了综合评价.评价结果表明,甘南黄河重要水源补给生态功能区的生态环境均属于中度和强度脆弱范围.并就此分析了其原因,以期对生态环境的治理提供参考. |
| 英文摘要 | The important water-supply ecological function area of Yellow River in South Gansu is located along the northeast edge of Qinghai-Tibet Plateau. It has the total area of 3 057 000 hm~2 and is a sensitive change zone of ecological environment in arid territory. The Maqu wetland, once honored as "the reservoir of the Yellow River", tends to be dry up and its ecological environment becomes very fragile. Based on the present ecological situation and the distribution of natural pasture, an appraisal system of ecological frangibility in the area is established by using the related ecological fragility appraisal method and analyzing the meadow ecological environment. The ecological function area can be classified as a medium or serious fragile region. Finally, the causes of ecological fragility are analyzed. It is expected that the study may provide a reference to ecological environment protection. |
