摘要
以2010年云南省古林箐省级自然保护区边界为基础，借助ARCGIS和Fragstats软件从时间和空间上统计分析2000—2010年保护区范围内的生态系统变化特征，计算生态系统转移矩阵和景观格局变化特征，并且对十年内的变化进行了分析总结。结果表明：古林箐省级自然保护区的生态系统构成在2000—2005年呈现出上升趋势，而在2005～2010年呈现下降趋势。景观格局指数从侧面反映这一规律。但是，从宏观上讲，云南古林箐省级自然保护区在十年间其生态系统构成和景观特征保持不变。生态系统构成在2000～2010年呈现出先上升后下降的趋势主要是由于森林生态系统的构成出现先上升后下降的变化情况。
Based on the boundary of Gulinqing provincial nature reserve, by means of ARCGIS and Fragstats software, this article from the temporal and spatial statistical analyze the changes in the characteristics within the scope of protection zone ecosystem, calculate the transfer matrix and landscape pattern changes of ecosystem, and analyze and summarize the changes within the ten years. The results show that the composition of Gulinqing provincial nature reserve ecological system in 2000 -2005, shows a rising trend, and from 2005 to 2010 presents a downward trend. And the landscape pattern index from the side reflects this law. But speaking from the macroscopic, provincial nature reserve of Yunnan Gulinqing in ten years the ecosystem structure and landscape characteristics remain unchanged. The ecological system in 2000 - 2010 showing increased after the first decline is mainly due to the composition of forest ecological system after rising first decline.
