摘要: 以云南小黑山自然保护区作为研究区域,利用Fragstats软件和Arcgis软件分析了其一级和二级生态系统的分布和面积变化,选取斑块数、平均板块面积、聚集度、类板块平均面积和景观连接度等5个景观指数来分析景观格局及其变化情况。结果表明,10年间,保护区内的草地生态系统面积增加,耕地减少,并且出现了城镇;保护区内的斑块数增加了36个,平均斑块面积降低了0.548 5hm2,聚集度指数增加了2.751 1,该区域内景观完整性度减少。

Abstract: With Yunnan Xiaoheishan Nature Reserve as the research area,the paper analyzes the distribution and area change in the level one and level two ecological system by using Fragstats and Arcgis and selects patch number,average plate area,aggregation,sector average area and landscape connectivity 5 landscape index to analyze the landscape pattern and its change.The results show that the protection of the region of the grassland ecosystem area increased,the arable land reduced,and the cities and towns emerged in the period of ten years.The number of plaques within the area of protection increased by 36,average patch area decreased by 0.5485hm2,aggregation index increased by 2.7511,indicating that the regional landscape integrity degree was decreased.

Key words: Xiaoheishan Nature Reserve, ecological environment, the temporal and spatial dynamic
