Abstract

In this work, a demographic study of Gaultheria glomerata and Disterigma empetrifolium was carried out in the Indiviso sector of the Baquerizo Moreno parish, Píllaro canton, Tungurahua province. The vegetation was analogous between montane forest and shrubby moorland, located at coordinates 01°18'S; 78°30'W, altitude 3400 m.a.s.l., where the Braun-Blanquet methodology for vegetation cover was adapted by means of plots, which were established randomly, the minimum distance between plot and plot was considered to be 100 meters. In the field work, the existing vegetation cover was quantified by percentages within 10 plots of 10x10m, in each of them were evaluated its subquadrants in the form of L, at each meter. The species were identified in the Herbarium of the ESPOCH, and the calculated data were 35.69% of vegetation cover for Disterigma empetrifolium and 13.19% for Gaultheria glomerata, which are in an abundance index of 2-3 on the Blanquet scale that tells us that it belongs to a medium abundant and abundant cover, Therefore, it was determined that Disterigma empetrifolium has a cover between 25-50%, thus concluding that it is in index 3 on Blanquet's scale, and Gaultheria glomerata was found in a percentage of 5-25%, concluding that this species is in index 2 on Blanquet's scale.
高山林中两种Ericaceae植物的种群状况
在这项工作中,在通古拉瓦省Píllaro州Baquerizo Moreno教区的Indiviso区进行了高卢菌(Gaultheria glomerata)和empetrifolium的人口统计学研究。植被类似于山地森林和灌丛沼地,位于座标01°18s;78°30'W,海拔3400 m.a.s.l,植被覆盖度采用Braun-Blanquet方法,随机建立样地,样地与样地之间的最小距离为100米。在野外工作中,现有植被覆盖在10个10x10m的样地内以百分比量化,在每个样地中以L的形式评估其子象限,每米。该物种在ESPOCH植物标本室中得到鉴定,计算数据为Disterigma empetrifolium占植被覆盖度的35.69%,Gaultheria glomerata占植被覆盖度的13.19%,在Blanquet尺度上的丰度指数为2-3,表明其属于中丰、丰覆盖,因此确定Disterigma empetrifolium的覆盖度在25-50%之间,属于Blanquet尺度指数3。小球高卢菌(Gaultheria glomerata)占5 ~ 25%,属于Blanquet指数2。
