  • Simulation models of short-rotation Forestry Production and coppice biology
    Biomass and Bioenergy, 1996
    Co-Authors: Sabine Philippot
    Abstract:

    Abstract The main aim of this review is to assess the suitability of an existing model of fast growing trees to further understand coppiced tree growth and regrowth. A model for coppiced fast-growing trees should include processes such as demography, partitioning, senescence, and should deal with carbon, nitrogen and also water relations. A model at the individual tree level instead of the stand level might be considered to take into account these different processes. A demographic approach, non-existent in the actual models, seems to be necessary to simulate the coppice phenomenon as the number of buds, leaves and stems determines the success of regrowth of a coppiced tree. There are two types of processes of interest for modelling coppiced trees that were found in the existing models, namely partitioning and water relations. But further work should focus on these processes as well as in the below-ground processes, i.e., dynamics of root growth and nutrient and water uptake, and leaf area expansion dynamics. An overall problem in developing a model for coppicing should be to define the adapted level of resolution for modelling the processes because this choice might affect the general accuracy of the model. It is proposed that a model for coppiced fast-growing trees should be either created or developed from different models that contain the processes of interest.

  • Identifying factors influencing the Forestry Production efficiency in Northwest China
    Resources Conservation and Recycling, 2018
    Co-Authors: Lichun Xiong, Fengting Wang, Baodong Cheng
    Abstract:

    Abstract Forestry industry has realized a rapid development in China due to the domestic and international demand for Forestry products. Considering the conservation of forest ecology, China has strived to improve the Forestry Production efficiency. Currently, the northwestern regions have been trying to recover the ecology and make economic growth through Forestry development. This research has assessed the Forestry Production efficiency in the six provinces in Northwest China. The stochastic frontier analysis was used to calculate the Production efficiency. To conduct a spatiotemporal analysis, we measured the regional differences in Forestry productivity and used global spatial autocorrelation to measure the spatial correlation degree. The regression model uncovered how the six factors influenced the Forestry Production efficiency in Northwest China. Our results show that from 2005 to 2015 the Forestry Production efficiency of the six provinces was declining. The spatial differences of the Forestry Production efficiency among the six provinces were gradually decreasing. Regarding the influencing factors, we found that the per capita GDP, forest coverage rate, the educational level of Forestry employees and the number of township Forestry technology stations had positive correlation with the Production efficiency. The collective forest tenure reform had a negative effect, which hindered the efficiency at the regional level in Northwest China. In the future, efforts should be made to enhance the infrastructure investment, the education of Forestry practitioners and the application of the advanced technology.
