流溪河国家森林公园森林景观稳定性评价

在ARC/INFO支持下,将广州市流溪河森林公园划分为16个景观类型,选取12个景观稳定性指标,建立森林景观稳定性评价指标体系,利用FRAG STATS软件定量计算景观指标值,建立景观指标标准化矩阵,构造森林景观稳定性综合评价模型.结果表明:流溪河森林景观类型的稳定性差异较大,其稳定性大小依次为硬阔叶林—阔叶混交林—竹林—软阔叶林—非林地—针阔混交林—杉木—木荷—相思—茶叶—马尾松—荔枝—湿地松—龙眼—木本果树—未成林造林地.

Evaluation on the Forest Landscape Stability of Liuxi River National Forest Park

Based on ARC/INFO,16 landscape types are assorted in Liuxi River National Forest Park of Guangzhou.The index system for evaluating its forest landscape stability is designed while 12 forest landscape stability indices are selected.Then,the values from the forest landscape stability indices are calculated by FRAGSTATS software in order to establish a standard matrix of landscape indices.And in this way,a synthetic evaluation model for forest landscape stability is also established.It proves that there are great differences among those landscape types in stability.The values of stability go from high to low as follows: horny broadleaved forest,broadleaved mixed forest,bamboo,soft broadleaved forest,non-forest land,coniferous and broadleaved mixed forest,Cunninghamia lanceolata,Sohima superba Gardn.et,Cham-Acacia spp,Camellia sinensis,Pinus massoniana,Litchi chinensis,Pinus elliottii,and Dimocarpus longan Lour.Therefore,the evaluation results can be helpful to forest landscape sustainable management.
