西北地区红桦天然次生林立地质量评价OACSTPCD
Evaluating Site Quality of Natural Secondary Forest of Betula albosinensis in Northwestern China
在陕西、宁夏、甘肃、青海等地设置红桦天然次生林临时样地85块,以年龄-树高、胸径-树高数据为依据,选取常用的9个树木生长模型拟合导向曲线,采用相对优势高法编制立地指数表和立地形表,并采用2种方法对4个不同地区的立地质量进行比较,实现对西北地区红桦天然次生林立地质量的科学评价.结果表明,立地指数和立地形的最优导向曲线方程分别为H=18.073/{1+exp[-(A-22.571)/9.144]}、H=19.793/{ 1+exp[-(D-12.21…查看全部>>
A total of 85 temporary plots of natural secondary forest of Betula albosinensis were set up in Shaanxi,Ningxia,Gansu and Qinghai provinces.Using age-tree height and DBH data as analytical re-sources,9 tree growth models were selected to fit the guide curve,and the site index table and site form ta-ble were compiled by the method of relative advantage height.The site quality in four different regions was compared by the two methods to realize the scientific …查看全部>>
