摘要
本文首次对五台山草地自然保护区五个植被垂直带中32种植物的48个样品中N、P、K、Ca、Mg、Mn、Cu、Zn、Co、Cr、Ni、Ph和Cd等13种化学元素的含量进行分析,初步揭示出本区植物中化学元素含量的区域特征以及在不同植被垂直带中草本、阔叶、针叶植物及其不同器官中元素的含量与分布规律.
In this paper, the contents of 13 chemical elements (N,P,K,Ca,Mg, Mn, Zn,Cu,Co,Cr,Ni,Cd,Pb) in different plant types of Natural Grassland Reserve of Wutai Mountain were studied. The contents of 13 chemical elements in various plant species were great difference. The average contents of N and Ca were higher than 10g/kg ; P, Mg, and K ranged between 1 and 8 g/kg, Mn, Zn, Cu and Cr between 10 and 100 mg/kg,Ni and Pb from 1 to 9 mg/kg; Co and Cd were less than 1 mg/kg. The plants in studied area were of high nutrition levels, which were able to meet the ha requirements of the animal, particularly the plants in the subalpine meadow were highly valuable for feeding animal.
