| Abstract: | Contributing factors resulting in low-yield, poor-quality and inferior-function of coastal forest of Pinus thunbergii were systematically studied based on the typical investigation for Pinus thunbergii coastal protective forests in Shandong Province. The types of inferior-function forests were divided, indexes for quantification were determined, and the main methods and countermeasures for improvement and reproduction of Pinus thunbergii inferior-function forests were put forward according to the site and growth properties. |
