Abstract:

One building model method of spatial structure optimizing in stand selection cutting has been put forward in this paper, this method breaks through the traditional idea of function objective optimiziation building model. Based on this method, one model of spatial structure optimizing in stand selection cutting has been built. The model integrates modern forest management theory, biodiversity preservation and information technology, and successfully connects with control method. The model belongs to nonlinear multi_objective integer programming, the model objective is spatial structure based on mingling, competition and distribution pattern, and mainly subjects to non_spatial structure. The model can be solved by Monte Carlo algorithm. As an example, one fixed-size plot is selected from Jingou forestry farm Wangqing forestry bureau Jilin province. This model is used to make selection cutting plan, an optimal selection cutting plan with spatial information has been gotten and benefits making management decision.
