【 摘 要 】

The objective of this study was to present the formulation of alternative models of regulation of the forest, with the inclusion of environmental and social characteristics for the management of the landscape. The models were constructed for a model farm, with an area of active planting of 3491 ha, divided into 135 management units. The regulation models were formulated as type I model, including integrity constraints for the management units. We use meta-heuristic genetic algorithm for solving the models. The alternative proposals were formulated: (i) the formulation of a classical model of regulation, (ii) application of adjacency constraints, and (iii) the restriction of age classes per compartment. The models were evaluated economically by the net present value (NPV) and environmentally by the Crop Area Index (CAI). The application of the technique of genetic algorithm is efficient for solving the constructed models with socio-economic and environmental constraints. The imposition of restrictions adjacency reduced overall NPV by about 8%, and the restriction of age classes per compartment was equal to 5% when this was required in seventh year. The imposition of adjacent and compartment restrictions showed an improvement in environmental quality of the regulatory model demonstrated by the CAI.
