摘 要: 本文对森林生态系统的三维褶皱指数进行改进,提出三维褶皱综合指数FS,I,C。利用该指数对广东湛江高桥红树林保护区不同潮带群落进行实证调查计算,得出外带样方1的Delaunay三角网结构最为复杂,综合指数为19.936。最后得出潮带群落稳定性是外带>内带>中带。该结果给红树林的保护提供一定的参考。总的来说,该综合指数方便进行系统结构稳定性的分析,可作为森林健康评价和稳定性评价的指标。 This study intended to improve the forest ecosystem three-dimensional pleat index and to put forward a new index FS, I, C. The new index was used to calculate the different mangrove tidal zones in Gaoqiao, Zhanjiang, China. The result showed that No.1 Delaunay triangulated network outside the tidal zone is the most complex, with FS, I, C of 19.935, and that the stability is better in area outside the tidal zone, followed by that inside the tidal zone, and then the middle tidal zone. The result provides a reference for mangrove protection. Overall, the index is convenient for analyzing the system structure stability, and can be used to assess forest health and stability.
