Study On Multi-Functional Evaluation Of Forest In Culai Forest Farm

As the main body of land ecosystem, forest has ecological, economic, social, and cultural and other functions. Multifunction forestry development, give full play to a variety of functions of forest, maximize meet people’s growing material and cultural needs, is the world forestry workers has long been striving for the goal, but also attracted much attention in recent years.Forestry multi-function study has important significance at present stage, first of all, the study on forest multi-function, setting up management system, exert forest functions, achieve the goal of multifunction forestry management, is to meet the needs of the historical mission of forestry in the new period. Second, in the past the traditional forestry theory under the framework of research is basically the study of timber production of a single function, an urgent need to further study of multi-functional forest related issues, multifunction forestry transformation provided the scientific basis for the implementation, better realize the change of traditional management to the multi-functional; Finally, in order to deal with in the development of national ecological function and long-term benefit and expectations regional forestry development goals and operators balance relations between and among their own rights and interests, safeguard the rights of and balance between the interests of the multi-function forest management must be put through to implementation, through a practical level, multi-function forest planning and management plan, and to make effective policies and regulations, such as security system implementation.The main research contents and results were summarized as follows:(1) Soil and water conservation and water conservation function: by using ecological economics value evaluation method, from the litter layer and a decomposition layer 2 level analysis, found that forest regions overall gap between dry matter accumulation quantity is not big, the same stand in the same amount of dry matter accumulation, a bit gap. Litter accumulation amount accounts for between 30% and 45% of total dry matter accumulation, deadwood tone falling objects under different forest types, leaf litter and half decomposition layer cumulate accounted for the proportion of the total cumulative amount, large gap and the total biomass of the maximum water holding capacity and half decomposition layer and litter layer of maximum water holding capacity and no obvious linear relationship. From the same forest types, forest types of half decomposition layer, litter layer of water conservation capacity of half decomposition bigger than litter layer, it should be and dry matter accumulation quantity related to the degree of decomposition layers.(2) To reduce greenhouse gas features: using the method of volume of biomass calculated Cu company mountain forest biomass of the main types of forest tree layer. Find there are still some gap between different forest carbon uptake, the same stand of a small co2 uptake evaluation level, close coupled carbon dioxide absorption function of the same tree species composition of forest gap is not big. At the same time of different tree species composition of forest carbon dioxide absorption exists great gap, different rating.(3)Biodiversity conservation function: to Culai Forest Farm forest biodiversity conservation value are analyzed. Study found that the area of forest biodiversity is stronger, scoring in the intermediate above. Tree layer and the undergrowth layer is not great, at the same time distribution uniformity organisms of the same forest types also exist certain differences.(4) Annual value of timber production function: Based on the annual value of buck to measure the economic value of forest in the study area, the estimate the economic value of the forest forest products. The study found that part of the stand growth is good, can better achieve the function of forest timber production. A few poor forest timber production function.(5) Choose Culai Forest Farm various functions actually company forest farm, with entirely for each function evaluation results to conduct a comprehensive expression, on the basis of this general expression function evaluation method using polygon area, multifunctional value of each stand, and on forest classification, advantage, stable equilibrium, complete lack of weak type three types, and the forest sub-compartment division. Found Culai Forest Farm most of the forest edge, complete can better play to the forest of multi-functional features, part of the stand in a stable equilibrium model, can take some measures to make up for the defect of management, enlarge the advantages, promote the multi-function, missing part stand weak type, this kind of small class need to invest a lot of work to improve the forest characteristics so as to promote the forest.
