| Abstract: | Forest management can effectively improve stand growth conditions,improve the growth of trees and forest quality.The effects of different intensitids of ecological thinning on the growth of Pinus densiflora plantations for seven years were studied in conjunction with forest maintenance subsidies from the central government.The reasonable intensity of ecological thinning for middle-aged Pinus densiflora plantations in middle south mountain area of Shandong was determined to be 20-30%,which provides reference basis for precise tending management of forest quality. |
