Optimal regional management and policy for forest resources under globalization of environmental problems in Slovakia

作为欧洲国家的环境要求之一，我们从空间约束的角度制定了自然更新的带状防护林管理方案，并构建了0-1整数规划模型进行求解。我们的实验表明，通过根据空间要求在空间和时间上重新分配收获带，我们可以减少引入带状防护林管理方案的影响。我们还构建了一个优化模型来处理不同所有权分布的个体林分的聚集问题，然后将所提出的模型应用于一个满足风暴防护要求的优化问题，该优化问题要求逆风方向采伐。

As one of the environmental requirements in European nations, we have formulated strip shelterwood management for natural regeneration in terms of spatially constrained harvest scheduling, and constructed the 0-1 integer programming model to resolve it. Our experiments showed that by reallocating harvesting strips over space and time subject to spatial requirements, we could reduce an impact of introducing the strip shelterwood management scheme. We have also constructed an optimization model to deal with aggregating individual forest stands spread over by different ownership, then applied the proposed model for an optimization problem subject to windstorm protection requirements, which demands harvesting toward the direction against wind.
