Study On The Evaluation System Of Forest Ecological Harvesting

Forest harvesting, one kind forest artificial intervention activity, will be positively or negatively, influence the forest resources quality, the forest ecological environment, the environmental service function and the overall benefit of forest ecosystem to some degree. Researches on the influences are basic study on the evaluation index system of ecological harvesting. The paper analyzes the evaluation of forest harvesting , study the evaluating methods to forest ecological harvesting and establishes a mathematical model of the environmental cost of forest operations. Evaluating model of forest ecological harvesting and evaluating model sustainable development of the forest resources affected by forest operations are put forward by utilizing a new way of combining Fuzzy Comprehensive Assessment with Fuzzy cluster Analysis. The models are analyzed and adjusted through the way of multi-objected. Based on the exploration and research on the evaluation model of forest ecological harvesting , the article proposes an analytical method to confirm whether the forest operation has realized ecological operation under the precondition of the forest resources sustainable development. This research provides one scientific and effective method to solve the complex problem how to evaluate index system of forest ecological harvesting.
