The Forest Health Assessment And Management Research In Kunming State Haikou Forest Farm

Abstract:The forest health is one of research hotspots in recent years, in order to achieve the stability and complexity of forest system, and forest byproducts to maximize, the service function of optimization, more and more people attempt to through rational forest management, forest sustainability and optimal health.Therefore, through the establishment of appropriate evaluation system of forest health, build a reasonable evaluation model of forest health assessment is very necessary.According to haikou forest category of resources survey and field TaZha, selected the representative typical sample area31indicators survey, selection of ecological public welfare forest19pieces and re select12pieces.Based on predecessors’research results and actual situation sample to get the data, haikou forest forest health assessment system is established, including community structure, stability, sustainability, productivity4criterion layer, there are16indicators. Points of ecological public welfare forest, and analysing the sample area health is made an evaluation analysis, put forward the appropriate management measures and technical methods.Using Delphi, AHP (that is, the expert scoring method, analytic hierarchy process) to calculate index weight, two types of indicators. Lin is consistent, but the score and weight calculation result is inconsistent. Weights of ecological public welfare forest to forest community structure, and the index of analysing with maximum stability index weight coefficient, and two types of forest standards are not uniform layer within the index weight coefficients, the result is mainly influenced by the expert scoring and stand function is different.Based on the comprehensive forest health assessment index, the level of forest health: no health, general health, sub-health, comparative health and five levels. Average health indices, the selection of sample area, the ecological public welfare forest (0.624) of samples under sub health condition, analysing sample area in general health condition (0.575). Results by general health of the sample in two classes are all in the position of the majority of the forest, the size of the index weight coefficient has important influence on the evaluation results. According to the results of the forest health assessment provides a measure ofbusiness:to haikou forest forest health is put forward according to the dominant benefit and forest type partition management, put forward the sustainable forest management, forest fire prevention, forest diseases and insect pests prevention, the main technical measures and forestry to establish forest health monitoring requirements of the network, in order to get timely and effective data to guide the forest health reasonable forest management.
