摘要
文章以北京2012年实施的百万亩造林工程项目为背景,基于地理信息系统技术,通过景观格局指数分析,研究平原造林对北京森林景观格局的影响。结果表明,平原造林显著增加了北京市市域森林生态资源,提高了平原区整体景观的均匀度,使平原区生态空间分布的均匀性和覆盖度范围增加,促进了平原区生产和生活空间与生态空间的融合分布;平原造林同时也促进森林、湿地等生态空间的形状更加趋于自然化的形状发展,有利于增加林地、湿地的边缘效应,促进生态系统的健康和生物多样性保护。
Based on the million mu afforestation project implemented by Beijing in 2012,this paper studies the impact of plain afforestation on the forest landscape pattern of Beijing using geographic information system( GIS) technology and landscape pattern index analysis. The results show that plain afforestation significantly increases the forest and ecological resources in Beijing,improves the evenness of the overall landscape in the plain area,increases the evenness and coverage of the ecological space distribution in the plain,and promotes the integrated distribution of the production and living spaces and ecological spaces there. At the same time,plain afforestation also contributes to the more natural development in shape of ecological spaces such as forest and wetland,which is conducive to increasing the edge effect of forestland and wetland and promoting the health of ecosystem and the protection of biodiversity.
