在中条山林区,首次发现国家Ⅱ级保护植物黄菠萝天然群落分布。利用GPS导航、地形图测算,结合环境因子对野生黄菠萝生存群落进行了分析。结果表明:小阴沟野生黄菠萝分布面积约0.5 hm~2;7个样方可划分为黄菠萝、山核桃、漆树3个群系;中度海拔、中坡位有利于黄菠萝生长,小阴沟黄菠萝多分布在20°以上的半阴坡,群落的盖度及优势种会影响黄菠萝幼苗的更新状况。
In the Zhongtiaoshan forest area, the natural distribution of the national grade Ⅱ protected plant pineapple is found for the first time. The use of GPS navigation, topographic map calculations, combined with environmental factors wild yellow pineapple living communities were analyzed. The results showed that the distribution area of wild yellow pineapple in Xiaoying ditch was about 0.5 hm ~ 2. The seven sample plots could be divided into three groups of yellow pineapple, pecan tree and lacquer tree. The medium altitude and medium slope position were beneficial to the growth of yellow pineapple, Yellow pineapple more than 20 ° in the distribution of semi-shady slope, community coverage and dominant species will affect the regeneration of yellow pineapple seedlings.
