摘要：混交度是描述混交林中树种混交程度的重要空间结构指数。由于传统混交度仅以对象木与最近邻木之间的树种异同为基础,并不考虑最近邻木之间的树种差异,不能完全反映树种的空间隔离程度。本文在传统混交度的基础上,提出一种新的混交度即树种多样性混交度。通过比较,树种多样性混交度更能反映树种相互隔离程度,是一个较好的林分空间结构指数。
Mingling is one of the important spatial structure indices to describe tree species segregation of mixed-species forest. Traditional mingling cannot completely express tree species segregation for it only compares the difference between objective trees and the nearest trees, and doesn't consider the difference of the nearest trees each either. Based on traditional mingling, a new mingling, tree species diversity mingling, has been put forward. By comparison, tree species diversity mingling is better than traditional mingling in expressing tree species segregation, and it is an available stand spatial structure index.
