| 摘 要： | 大通县地处青藏高原与黄土高原过渡地带,生态区位十分重要。利用1995年和2005年2期TM遥感影像,基于RUSLE土壤侵蚀预报模型和GIS技术,估算出大通县2个时期土壤侵蚀的定量数据,阐明了大通县土壤侵蚀变化状况。1995年土壤侵蚀总量为2 938.17×104 t,侵蚀模数为68.55t.hm-2.a-1;2005年土壤侵蚀总量为2 160.07×104 t,侵蚀模数为51.83t.hm-2.a-1,从1995年到2005年大通县土壤侵蚀状况有所减轻。

| Abstract: | Datong is located in the transition zone of Qinghai-Tibet Plateau and the Loess Plateau,a very important ecological area.Based on soil erosion prediction model(RUSLE) and GIS technology with the application of remote sensing in 1995 and 2005,the quantitative soil erosion and the transformation status of Datong county were esimated.The actual quantity of soil-erosion and the soil erosion modulus were 2 938.17×104t,68.55 t·hm-2·a-1 and 2 160.07×104 t,51.83 t·hm-2·a-1,respectively in 1995 and 2005,indicating that soil-erosion status was improving gradually with the reduction of soil-erosion quantity from 1995 to 2005. |
