摘要
通过对比分析景观指数的变化情况 ,评价了乌苏里江国家森林公园总体规划方案的合理性 .计算发现规划前后斑块数从 413减少到 40 1,香农均匀度指数从 0 75 5提高到 0 787,优势度指数从 2 5 5 47减少至 2 4 5 0 0 .景观破碎化程度降低 ,反映廓道特征的r指数、a指数和主要景点之间的景观引力值都有所增加 ,表明规划改善了公园的景观空间结构 ,提高了景观系统的稳定性和风景质量 ,有利于生态环境保护和生态旅游的发展 .
Landscape indices provide quantitative information about landscape pattern and predict some ecological processes.Rationality of Wusuli River National Forest Park' general planning program was evaluated by comparatively analyzing the landscape indices change.The results indicated that the number of patch decreased from 413 to 401,Shannon's evenness index increased from 0^755 to 0^787,and predominant index decreased from 25^547 to 24^500.In addition,the network connectivity index,the network circuitry index,and landscape attractive power between scenic spot were increased,and the extent of landscape fragmentation was decreased.So,the planning would improve the landscape pattern,enhance ecosystem stability and landscape quality,and be useful for ecological protection and ecotourism development.
