摘要
以景观多样性作为切入点,基于森林资源监测数据,运用地理信息系统和景观生态学原理,分析大理市境内的苍山区域 9 种主要景观类型及其空间分布现状,梳理当前存在的生态问题,提出生物多样性保护的具体措施.结果表明:林地景观是对整个区域生态过程起主要控制作用的基质;河流和道路景观作为廊道散状分布穿插于林地基质中,发挥通道与阻隔的双重作用;草地景观呈现退化趋势.从总体上看,研究区景观连片完整,自然连接度好,土地利用类型单一,有利于物种保护,人为干扰影响主要在实验区.对此,针对不同的功能分区提出了相应保护建议.
Abstract
Starting with landscape diversity and utilizing monitoring data of forest resources alongside geo-graphic information systems and landscape ecology principles,this paper examines the nine primary landscape types and their spatial distribution in the Cangshan area of Dali City.It identifies current ecological issues and proposes specific strategies for conserving biodiversity.The results show that the forest landscape serves as the matrix that plays a significant role in controlling the ecological processes of the entire region.River and road landscapes are scattered throughout the forest matrix as corridors,playing a dual role as both channels and barriers.The grassland landscape showed a trend of degradation.On the whole,the landscape of the study area is complete,with good nat-ural connectivity,and a single land use type,which is conducive to species protection.The influence of human dis-turbance is mainly in the experimental area.In this regard,corresponding protection suggestions are proposed for different functional partitions.
