Optimal Management Density of Larix principis-rupprechtii Plantations of Ningdong Forestry Bureau in Shaanxi Province
摘要
Abstract
Based on the data from the sampling plots of Larix principis-rupprechtii plantations of the forestry farms of Ningdong Forestry Bureau in Shaanxi Province,this paper studied on the regression models of DBH and the crown area ( Cws),and used this to calculate the theoretical density and optimal management density. The results showed that; 1) the optimal regression model of DBH-Cws was Cws =0. 044 6D2 - 0. 755 1D+6. 753 3. 2) the table of theoretical density and optimal management density were established under a series of canopy densities between 0. 7 - 0. 9 of L. principis-rupprechtii plantations. 3) the canopy density of 0. 7 was the optimal management density.关键词
