摘要
针对帽儿山地区退化森林生态系统实际情况,以原始阔叶红松林为参照,运用多样性指数、构成指数、结构-多样性指数综合评价,通过对帽儿山7个典型示范区的分析,结果表明,示范区6营造樟子松与水曲柳带状混交林的健康恢复状况最好,符合实际情况,为山地退化森林生态系统最优恢复技术的选择提供决策支持。
According to the actual situation of degraded forest ecosystem in Maoershan Mountains region, the comprehensive evaluation combining diversity indexes, component index （CI）, and community structure-diversity index （CSDI） was used referring to original broadleaved Pinus koraiensis Sieb. et Zucc. forest. The results showed that, through analysis on 7 typical demonstration sites of Maoershan Mountains, the best restoration of Pinus sylvestris var. mongolica Litv. and Fraxinus mandshurica Rupr. beh-shaped mixed forest was provided in No.6 demonstration site. So the decision support could be provided for the selection of optimized restoration techniques of mountain degraded forest ecosystem.
