Plantation density effect characteristics of black locust and pitch pine plantation in the West Shanxi Province
摘要
Abstract
According to data of 59 sample trees of black locust and pitch pine plantations in the west Shanxi, the variation characteristics of density effect with stand age were investigated to draft growth model of DBH of single and density effect model by fitting . The results showed as folliws the density effect became more and more obvious with the increase of forest age, while breast diameter in growth progress and negative correlation coefficient of density increased. When the forest age reached a certain standard, the correlation coefficient growth rate declined. The forest ages were 13 years old Robinia pseudoacacia on the north-facing slope; 10 yeare old on the semi-north-facing slope; 8 years old R. Pseudoacacia on the semi-north-facing slope in Ji County; 13 years old Pinus tabulaeformis Carr on the semi-north-facing slope and south-facing slope in Fangshan County. Different slopes gave different responses for density. The correlation coefficient of north-facing slope R. Pseudoacacia Linn in Fangshan County was smaller than that of semi-north-facing slope; the correlation coefficient of south-facing slope of P. Tabulaeformis Carr in Fangshan County was smaller than that of semi-north-facing slope. Plantation in different slope aspect had different first artificial afforestation density and tending management.关键词
