通过设置临时标准地，对天然米槠林皆伐炼山后种植的１７年生人工米槠林和自然保护区天然米槠林进行植物区系组成的研究结果表明：天然林科属种数较人工林多；２者共有科属种分别占人工林总科数７５％，总属数９４％和总种数９３％；蕨类植物天然林少于人工林，而双子叶植物和单子叶植物天然林多于人工林。属的分布型分析，２者以热带成分为主，但人工林热带成分略高于天然林。种的分布型分析，人工林和天然林与广东、广西同类型区系共有种的百分比较高
By setting up temporary standards, the study on the flora of 17-year-old artificial Mianyang mills protected by Miriam Forest and the natural Mirabilis monglin Nature Reserve after natural mulberry cultivation shows that the species number of natural forest is more than that of artificial There were 75 families with total genera and 94% of the total species, respectively. The natural ferns plantation was less than the artificial plantation, while the dicotyledonous plants and monocotyledonous plants were natural Forest more than plantation. The genus distribution analysis, the two tropical components, but the tropical component of plantation slightly higher than the natural forest. Species distribution analysis, plantation and natural forests and Guangdong, Guangxi, the same type of species sharing a higher percentage
