摘要
以西双版纳勐腊国营林场热带林为研究对象,以2006年森林资源二类调查数据为信息源,在ArcGIS支持下,把勐腊国营林场整个森林景观划分为8种景观类型,并选取10个景观格局指数作为稳定性评价指标体系,在Fragstats计算各景观类型的指数值基础上,建立了景观稳定性评价指标标准化矩阵;运用主成分分析法,在SPSS13.0支持下,构造了热带林景观稳定性综合评判模型,对勐腊国营林场各类型森林景观进行稳定性排序。研究结果表明:勐腊县国营林场热带林景观稳定性差异较大,其稳定性大小依次为:其他阔叶林—橡胶林—栎类林—茶叶—竹林—经济乔木林—思茅松林—其他灌木林。该结果可为西双版纳热带林的经营保护提供技术支撑。
Taking the state-owned forest farm in Mengla County in Yunnan Province as study object, 8 landscape types were divided with the help of ArcGIS and grid data was created. Based of 10 landscape pattern indices being choosed, the pattern indices of each landscape pattern was calculated with the help of Fragstats. At the same time, based on standardization matrix being established, landscape stability assessment models were created by using principle component analysis method, sort the stability of each forest landscape in Mengla state-owned forest farm. The result indicates that there are great differences among those landscape types of stability in Mengla stateowned forest farm. The stability from high to low are： other broad-leaved forest, rubber forest, oak forest, Camellia sinensis, bamboo, economic arbor forest, Pinus kesiya, other shrubbery.
