A study was conducted of the soil physical properties of Pinus massoniana plantation under different intensities of fire disturbance.

We evaluated the impact of litterfall on soil respiration under a Pinus massoniana plantation in Tianjiling National Forest Park of Changsha,Hunan,using a field study with litterfall exclusion and addition in a full factorial design.

By using the data from dominant tree stem analysis and selecting the proper growth equation of Pinus massoniana plantations,this paper built up a polymorphic site index model for the plantations,which expresses their site index as an explicit expression of tree age and dominant height,and conducted an optimization solution to their model parameters by employing genetic algorithm.

Carbon dynamics of Masson pine plantation in different age classes (8 a, 14 a, 23 a, 38 a) in the central hilly area of Guangxi, China was studied based on the estimation of their biomass and net primary production (NPP).

Based on the investigation of the geographical district and site type characteristics of Masson pine plantation in Yichang County, site quality evaluation system of Masson pine plantation was estalblished by means of Richards growth equation and quantitative theory Ⅰ.

Based on the stand growth table and the data of input and output of masson pine plantation in Hubei Province, the management model of masson pine plantation was compiled by using the discount cash flow method.
