Study on the vegetation forms and characteristics of community in Nuluerhu Mountain Nature Reserve,Liaoning Province

努鲁儿虎山自然保护区植物种类繁多,植物资源丰富,部分地段植被属于植物群落演替的顶极阶段。经过调查分析,该区地带性植被为油栎类、槭类和山杏等乔木树种组成的典型温带落叶阔叶林,同时存在4种植被型和7种植被亚型10个群系20个群丛,体现出由温带草原向温带落叶阔叶林带过渡的特征,具有重要的生态价值和保护价值。在分析自然保护区植被保护中存在问题的基础上,提出了相应的保护对策。
