利用重要值等指数研究物种替代特征表明:柞蚕场以花木蓝(Indigofera kirilowii)灌草丛为主,麻栎(Quercus acutissima)和胡枝子(Lespedeza floribunda)的重要值相同,说明天然栎林树种在强烈地人为干扰经营下其优势度在受到严重胁迫,生态敏感性增加。对实施不同经营措施的三大块样地的物种多样性进行分析结果表明:3种类型栎类林的植被丰富度无显著差异,植被均匀度差异显著。 The study on the substitution characteristics of the species using the index of important values ​​indicated that the Tussah field was dominated by Indigofera kirilowii shrubs and the important values ​​of Quercus acutissima and Lespedeza floribunda were the same, Under the disturbed operation, the dominance of the people is severely intimidated and their ecological sensitivity increases. The results showed that there was no significant difference in the vegetation richness between the three types of oak forest and the difference in vegetation evenness was significant.
