石栎、青冈栎和杉木混交林分的空间结构
Spatial structure analysis on mixed forest of Tan oak, blue Japanese oak and Cunninghamia lanceolata in Xiaoheigou of Yixing County
摘要
Abstract
In order to understand the structural characteristics of high-quality forest, applied the traditional stand structure indexes combining with mingling, neighborhood pattern, neighborhood comparison and opening degree to have analyzed spatial structure of mixed rock oak and fir in Black Trench in a natural conservation in the suburbs of Yixing, Jiangsu Province. The results showed that: There are rich species in the oak trees and firs mixed forest. There are 9 stocks in the tree layers, the diameter structure of community was continuous, and the vertical structure of stand could be divided into 3 layers. The average mingling of the stand was 0.516, showing that the mixed degree of the forest was high; The neighborhood pattern was 0.482, indicating that tree position in the stand was random distribution. The neighborhood comparison was 0. 482, and there were nearly 40％ trees in the stand being dominant. The population of rock oaks and firs are dominant now, and the community is in a relatively stable state.关键词
