中文摘要:
      通过外业调查,在云南省玉溪市新平县云南松纯林中分别设置3个计划烧除样地和3个未烧 除样地(对照),9个计划烧除样方和9个未烧除样方,分层测定计划烧除样地内的林火烈度等火行为特征。记录植物种类,测量灌木层和草本层的高度、盖度,分析其科属分布特点、相对重要值、物 种丰富度、物种均匀度、Shannon-Wiener多样性指数和Simpson多样性指数等。研究结果表明,在短时间内,计划烧除使得物种数量降低,主要灌木的重要值上升;短时间内计划烧除使得植被的 Simpson指数、Shannon-Wiener指数降低,Pielo均匀度指数升高;短时间内计划烧除降低了植物多 样性,但使主要灌木的优势度和均匀度增加。研究计划烧除对云南松纯林植物多样性的影响,研究结果能为计划烧除提供科学依据,为林火管理提供技术支撑。
英文摘要:
      Through field surveys, three prescribed burning plots and three unburned control plots were established in pure Pinus yunnanensis forests in Xinping County, Yuxi City, Yunnan Province, along with nine prescribed burning quadrats and nine unburned quadrats. The fire behavior characteristics, including fire intensity, were measured in different layers within the prescribed burning plots. Plant species were recorded, and the height and coverage of shrub and herb layers were measured. The study analyzed family and genus distribution patterns, relative importance values, species richness, species evenness, Shannon-Wiener diversity index, and Simpson diversity index. The results showed that, in the short term, prescribed burning reduced the number of species but increased the importance values of dominant shrubs. Additionally, prescribed burning decreased the Simpson and Shannon-Wiener indices while increasing the Pielou evenness index in the short term. Although prescribed burning temporarily reduced plant diversity, it enhanced the dominance and evenness of major shrub species. This research on the effects of prescribed burning on plant diversity in pure Pinus yunnanensis forests provides a scientific basis for prescribed fire management and offers technical support for forest fire control.
