根据松纵坑切梢小蠹的主要生物学特征,通过分析抚育间伐持续控制松纵坑切梢小蠹虫害的机理,应用复杂适应系统(CA S)理论,建立了模拟松纵坑切梢小蠹虫害的一种动态演化数学模型,并讨论了模型的收敛性.然后选用昆明小哨林场为背景,进行了各种抚育间伐决策的仿真,从中优选抚育间伐决策.结果表明:模拟优化方案与实际调查统计分析结果一致:均为弱度间伐与中弱度间伐控制蠹害效果最好.最后通过森林积材量与虫害程度之间的优化,给出了抚育间伐的优化策略.
According to the main biological characteristics of Pinctada davidiana, the mechanisms of controlling pests of Pinus ponderosa by continuous thinning were analyzed. Based on the theory of complex adaptive system (CA S) And the convergence of the model was discussed.Secondly, based on the Kunming Small Sentry Forest Farm, the simulation of various tending thinning decisions was carried out, and the thinning decision-making was optimized.The results showed that the simulation optimization scheme and The results of the survey and survey are the same: both the weak thinning and the moderate thinning domination have the best effect.At last, the optimization strategy of tending and thinning is given through the optimization of the forest biomass and insect pests.
