Abstract


Scientific Classification Gradation and woodland on the to promote woodland optimal allocation of resources, and strengthen the management of forest land has a very important practical significance, is an important foundation for deepening forest tenure reform. Learn from the achievements of our forest site evaluation build woodland Classification Gradation and technology system. Determine the two levels and the ecological and economic quality grade work on a comprehensive analysis of the various factors affect the the woodland quality of economic, social and natural factors, according to the site type, site quality analysis and suitability evaluation to determine the quality of woodland natural quality level determined by the woodland site level; according to the findings of the regional land use and socio-economic level, to determine the composite index of the woodland. Determine aspects of site quality level, select the topography, soil type, slope, aspect, soil thickness, thickness of the surface soil, slope position, slope, elevation of eight of the woodland natural qualities of the more significant factors, each factor level coefficient method level, the use of screening the stepwise discriminant law from eight fixed factor dominant factor, based on the dominant factor level coefficients and hierarchical discriminant function designated woodland site quality grade unit; determine aspects of the ecological and economic quality grade, to delineate woodland site quality level unit basis, from the existing forest resources inventory and asset assessment survey to examine the factors select a representative community structure, surface cover, species diversity, skidding conditions, the transport distance, the operating level of human disturbance degree, the supply potential of eight to affect the more significant factor in forest land use and income level as the main factor of this study, the comprehensive peer experts and engaged in forest resource assets assessment experience a wealth of first-line professional and technical personnel, using the analytic hierarchy process and Delphi a combination of methods to determine the weight of eight factors to determine the matrix and factor scores, the establishment of appropriate evaluation system. Elaborate on the origin of government rent and woodland trees from woodland revenue estimates introduced value formula derivation. Woodland classification and grading based on the combination of the current woodland and forest assessment method, based on the forest land value and the value of the normal forest stands the same reality stand stock only affect the value of the trees in the woodland above inference premium benchmark for woodland, the value of the trees as well as reality stands evaluate, establish a set of estimation methods. Raised through woodland revenue estimate is derived the woodland formula, the value of forest resources in the value of ecological benefits of the introduction of the of woodland valuation techniques system thinking.
