摘　　要：基于3S技术,并结合景观生态学方法对白马雪山自然保护区景观格局变化进行研究分析.结果表明,1975—1990年期间,林地、农牧地和非林地面积分别增加48.53 km2、68.85 km2和172.91 km2,景观破碎度和异质性下降,景观优势度和聚集程度明显增加;1990—2000年期间恰好相反,林地、农牧地和非林地面积都有所下降,水体与荒地面积分别增加154.74 km2和36.68 km2,景观破碎度和异质性增加,优势度与聚集程度反而降低.景观格局变化影响区域生态环境与生物多样性的保护机制,因此对不同时段景观变化研究具有重要意义.The paper employed 3S technology and landscape ecology method to study and analyze the variation of landscape pattern of the national nature reserve of Baima Snow Mountain. The result showed that from 1975 to 1990, the acreage of forest land, agriculture and animal husbandry, non-forest land increased by 48.53km^2, 68.85km^2 and 172.91km^2, respectively, the fragmentation degree and heterogeneity of the landscape decreased, and the aggregation degree and dominance increased. However, all of these are contradict with those from 1990 to 2000, the forest land, agriculture and animal husbandry,non-forest land decreased, and the water body and desert area increased by 154.74km^2, 36.68km^2, respectively. The fragmentation degree and heterogeneity of the landscape increased, polymerization degree and dominance decreased. The variation of landscape pattern influences the protective mechanism of regional ecological environment and biodiversity, so that it has important significance to research the variation of landscape in different periods.
