2000-2010年医巫闾山国家级风景名胜区生态系统功能变化评估

摘要

Based on remote sensing data and ground data, using geographic information systems (GIS)and remote sensing technology (RS), study ecosystem function of Yiwulvshan national nature scenic area in 2000-2010, in order to provide a reference for better environmental protection of national nature scenic area. The result shows:the land use of Yiwulvshan national nature scenic area did not change significantly;the capacity of water conservation and soil con-servation increased, due to the increase of vegetation coverage; net primary productivity decreased 5.27%, and changes of biodiversity conservation capacity is small. Ecosystem function of Yiwulvshan national nature scenic area from 2000 to 2010 was stable, which showed that existing management regulations protect the ecological function effectively.%以遥感数据和地面数据为基础，借助地理信息系统（GIS）和遥感技术（RS）对医巫闾山国家级风景名胜区2000—2010年生态系统功能进行研究，为能更好地保护风景名胜区的环境提供参考。结果表明，医巫闾山国家级风景名胜区的土地利用基本无明显变化；水源涵养能力和土壤保持能力有少量增强，主要是由于植被覆盖度的增加；植被净初级生产力有所下降，10年间下降5.27%；生物多样性有少量提高。总体来说，10年间，医巫闾山国家级风景名胜区生态系统功能基本处于稳定状态，表明现有的管理条例有效地保护了区域的生态功能。
