The main trend in sustainable forest management is to use the forests to perfectly accomplish their environmental conservation role parallel with supplying forest products to fulfil communities' requirements. However, forests handed over to the local community are commonly found poor and require driving solutions to make them more stable and productive. The question is how to use the forest in sustainable management. The paper presented the methods for estimating forest products and benefits use based on the so-called sustainable forest model. The sustainable forest model is limited to stem number-diameter distribution ( /DBH distribution), which follows probability N density functions. Meyer function is opted to be used in this research because it can make a rather good simulation of N/DBH distribution having the shape of decreasing curves. The results showed that the proposed N/DBH distribution of the sustainable forest model of group II and III has N = 276·e ; = 164·e (respectively). This forest model will help identify the benefit levels to the community, make suitable and -0.096D -0.063D N straightforward planning of wood exploitation, and reduce the costs by comparing the number of trees of the researched forests with that of the model.
