摘　　要：以GIS和RS为平台,通过对青海省鱼卡煤矿周边区域的土地利用、植被、土壤及土壤侵蚀等方面进行研究,来揭示区域生态环境状况。研究表明,作为西部干旱和半干旱区的绿洲荒漠过渡带,区域地带性景观为荒漠景观,区域生态环境较为敏感,加上长期煤矿开采的扰动,使得该区的生态环境不断恶化,区域土壤侵蚀严重,土壤贫瘠,生物生产力低,植被一旦破坏恢复起来极为困难。最后针对研究区生态环境状况特点,探讨了该区域的发展方向。研究结果较好地反映了区域的生态环境状况,并可作为区域生态综合整治的参考依据。Based on remote sensing and GIS technology,the land use,vegetation,soil and soil erosion around the Yuka mining area of Qinghai province were analyzed,revealing the eco-environment status of this area.As indicated by the results,as the desert-oasis ecotone in the arid and semi-arid area of West China,the landscape of this area was dominated by desert,and its eco-environment was very fragile,with the influence of the long-term coal mining,its eco-environment was deteriorating,and soil eroded seriously,the poor soil led to the low biological productivity,and it was very difficult to restore the vegetation once destroyed.According to the eco-environmental features of this region,its development orientation was discussed.The research results well reflected the eco-environmental conditions of this region,and provided references for the comprehensive improvement of ecology.
