摘要
系统地阐述了FORECAST模型的原理,其应用过程包括数据收集与调准、生态系统的构建、设置管理模式或自然干扰情景、模拟情景、分析模型输出结果.目前许多国家已开始运用该模型,模拟了不同管理措施对树木生产力的影响等.该模型不受特定的树种、立地条件的限制,可在很大程度上提高预测的准确度,成为预测森林经营管理的最佳模式.
This paper described the principle of forecast model and its application process including data collection,and alignment,ecosystem construction,management model or natural disturbance scenarios and simulation scenarios,model output.At present,many countries have begun to use the model to simulate the impact of different management measures on long-term productivity of trees.This model has become the best model for forest management,since it can greatly improve the forecast accuracy without subjecting to specific tree species and site conditions.
