林分生长规律是森林经营的理论基础之一,研究杨树速生丰产用材林(以下简称“丰产林”)的生长过程,编制杨树丰产林生长预测表,可以预估林分未来的生长量,鉴定森林经营的效果,并为制订森林经营技术措施提供依据。我省由于发展杨树丰产林的历史尚短,以往省内缺乏杨树丰产林生长预测方面的系统研究。为提高我省杨树丰产林的经营管理水平,我们在制订山东省杨树速生丰产用材林标准的过程中结合进行了杨树丰产林生产过程及生长预测的系统研究,编制了杨树丰产林生长
The growth pattern of stands is one of the theoretical bases for forest management. To study the growth process of fast-growing and high-yield timber plantation of poplar (hereinafter referred to as “high yield forest”), and to compile the forecast table of growth of poplar plantations, we can estimate the future growth of stands, Identify the effect of forest management and provide the basis for formulating technical measures for forest management. Due to the short history of poplar production in our province, there has been no systematic study on the prediction of the growth of Poplar production in the past in the province. In order to improve the management level of poplar-rich poplar in our province, we systematically studied the production process and growth prediction of poplar-poplar in the course of formulating the standard of fast-growing high-yield timber of poplar in Shandong Province.
