鲁中南山区黑松人工林抚育间伐起始期及适用强度研究

Research of Beginning Period and Applicable strength of Forest Thinning in Young Plantation of Pinus Thunbergii Parlin Middle South Mountain Area of Shandong Province

森林抚育能够有效改善林分生长条件,提高林木生长量和森林质量。本研究结合中央财政森林抚育补贴项目,历时7年,开展了不同起始期、不同强度抚育间伐对黑松人工林生长影响的试验研究,确定了鲁中南山区黑松人工林适宜的抚育间伐起始期及适用强度分别为林龄10~11年、强度20%,为黑松人工林抚育管理提供了参考依据。

Forest management can effectively improve stand growth conditions,improve the growth of trees and forest quality.In conjunction with the project of forest maintenance subsidies from the central government,for seven years,the effects on the growth of different starting periods and different thinning intensities of young plantation of Pinus Thunbergii Parl were studied.The suitable beginning period and applicable strength of forest thinning in young plantation of Pinus Thunbergii Parl in middle south mountain area of Shandong province was determined to be forest age 10~11 years,intensity 20%,which provides reference basis for precise tending management of forest quality.
