Forecasting the Variation Tendency of Forestry Sustainable Management Status with MACD and KDJ Methods

For sustainable management of forest resources,not only the status of forest management must be judged at certain point of time,but also the variation tendency of the status must be well understood.The fluctuation,dynamic characteristics and seasonal rhythm of forest sustainable management status and its variation tendency are discussed.The variation direction,speed and turning point of forest sustainable management status are forecast with Moving Average Convergence and Divergence(MACD) and Stochastic(KDJ).Corresponding cycle parameters are discussed and its application feasibility is analyzed in the paper.
