基于景观指数的梅山地区马路溪村景观格局分析

Landscape pattern analysis of Maluxi village in Meishan area based on landscape index

为了对马路溪村的生态保护、景观格局的优化与提升设计提供理论基础,以马路溪村的航拍图和遥感地图作为数据来源,并基于ARCGIS和FRAGSTATS的技术支持,从斑块、类型和景观水平3个层次选取相应的景观格局指数对马路溪村景观格局的总体特征、景观形状指数、景观多样性和景观镶嵌模式进行了分析.结果表明:林地斑块占地面积和最大斑块占景观面积的比例最大,其构成了马路溪村的景观基质,且结构与功能稳定;耕地、铺装与建筑斑块数量多且景观形状指数大,受人类活动干扰较大,破碎化程度相对较高;道路与水体构成了马路溪村的景观廊道,马路溪村景观属于指状型与斑块散布型的混合镶嵌模式,生态系统较稳定,景观多样性与物种多样性较高;马路溪村的景观格局总体属于一种适宜的生态格局.

To provide the theoretical basis for the ecological protection,landscape pattern optimization and upgrading design of Maluxi village,taking the aerial photographs and remote sensing maps of Maluxi village as the data source,and based on the technical support of ARCGIS and FRAGSTATS,the corresponding landscape pattern indices were selected from three levels of patch,type and landscape level to analyze the overall characteristics,landscape shape index,landscape diversity and landscape mosaic pattern of Maluxi village.The results show that the woodland patch occupies the largest proportion of the landscape area,which constitutes the landscape matrix of Maluxi village,and its structure and function are stable,and the number of cultivated land,pavement and building patches is large and the landscape shape index is large,and it is greatly disturbed by human activities,and the degree of fragmentation is relatively high.The road and water body constitute the landscape corridor of Maluxi village,and the landscape of Maluxi village belongs to the mixed mosaic pattern of finger-shaped and patch-scattered type,with stable ecosystem and high landscape diversity and species diversity.Maluxi village landscape pattern generally belongs to a suitable ecological pattern.
