罗山国家级自然保护区森林植被资源监测与分析

Analysis and Monitoring of Forest Vegetation Resource in Luoshan National Nature Reserve

摘要: 根据罗山保护区的典型地带性特点和森林植被资源特点，按照长期定位监测的要求，在保护区设置用于长期定位监测植被变化情况的样地，对罗山的植被资源定位监测，系统分析其植被多样性，为罗山自然保护区科学管理与可持续发展提供依据。结果表明：以草地和灌木地为主的山体共有木本植物32种，草本植物168种。小罗山以草本和灌木植物为主，平均高度分别为16.54 cm和36.69 cm；大罗山植被分布复杂、种类多，植被以草地和灌木地为主的山体物种丰富度在0.007~0.009这之间。罗山大多数植物种多度小于20%，木本灌木的多度大于50%，草本植物种的频度小于40%。调查的几条路线中，物种丰富度指数差异较小。

Abstract: According to the typical zonality and forest vegetation characteristics of Luoshan nature reserve, and long-term located monitoring requirement, we set up sample plots in Luoshan nature reserve for long-term located monitoring of forest vegetation to analyze its dynamic changes and biodiversity that will provide reference for scientific management and sustainable development in Luoshan nature reserve. The result shows that there are 168 herbaceous plants and 32 woody plants for all grassland and shrub plots. The small Luoshan only has herbaceous plants and shrubs, and their average height is 16.54 cm and 36.69 cm respectively. The plants in big Luoshan are more diverse and complex, and species richness of grassland and shrub plots is between 0.007~0.009. The abundances for different plants in Luoshan are less than 20%; the abundances for woody plants are greater than 50%, while frequentness for herbaceous plants is less than 40%. There is no big difference in species richness index of the plots in Luoshan.
