Abstract

Abstract:

Based on the investigation data from the sample plots of Eucalyptus spp.Cunninghamia lanceolata, Pinus massoniana, Larix spp. and Pinus sylvestris var. Mongolica etc, and combining with other results of research projects on plantation, main natural factors that effect the productivity of Chinese forest plantation were studied systematically. The results showed: (1) According to the actual distribution of Chinese plantation and the site quality, the average climatic-site potential of production of Chinese forest plantation was 8.6 m³/hm²·a. (2) Because the area proportion of sapling stand to the total plantation area was too large, there had been a 31%～35% reduction in the overall level of forest productivity of China plantation.

Key words: Plantation, Productivity, Natural factors, Probing problems
