摘要
利用SPOT5高分辨率卫星影像,对云南哈巴雪山自然保护区的景观资源进行景观生态分类,并在此基础上,对保护区的景观格局进行分析。结果表明,保护区景观可划分为1个景观类、9个景观系、18个景观型,景观多样性指数为2.315,丰富度较高;保护区景观破碎度为0.009,景观总体上较为完整;保护区的中海拔区域(2 500~4 000 m)的斑块多度较高,破碎度和分离度较小,是保护区景观和生物多样性保护的重点区域。
The landscape ecological classification of Habaxueshan Nature Reserve in Yunnan Province was made by using SPOT5 high resolution satellite images,and the pattern of landscapes was analyzed based on the classification.The results showed that the landscape resources of the Nature Reserve could be divided into 18 landscape types of 9 landscape classes within one categery.The landscape diversity index was 2.315,which indicated high abundance.The fragmentation index was lower(0.009) and which indicated the landscapes of the Nature Reserve were well conserved.High abundance index and relatively lower dispersion and fragmentation index implied that the important of the middle elevation zone(ranging 2 500~4 000 m)of the Nature Reserve for landscape and biodiversity conservation.
