Abstract

Abstract:

Based on the China's forest simulation and optimization platform FSOS(Forest Simulation Optimization System) using simulated annealing algorithm,this paper preliminarily discussed the forest land utilization planning at the national level in Papua New Guinea.Scenario 1:Continue to maintain the existing mode of natural forest management.Scenario 2:Select part of the wasteland suitable for forest to manage plantations and protect natural forest,and carry out short-term(25 years) and long-term(200 years) utilization and protection planning of its woodland,and compare it with the scheme of planting palm oil.The simulated analysis showed that if scenario 1 was adopted,maximum timber output would be 10 million m³ per year,and almost all of the natural forests would lose at the end.If scenario 2 was adopted,the timber output of plantations would significantly increase and most of the natural forests have been effectively protected,with the natural forests being effectively conserved.The result of simulated analysis provides a reference for planning natural forest protection and timber plantation establishment of PNG.

Key words: forest-land use planning, natural forest protection, plantation timber production, forest carbon sequestration, Forest Simulation Optimization System(FSOS), Papua New Guinea
