The Evaluation And Analysis Of The Value Of Forest Ecological Service Function In Laoshan

With the rapid development of economic globalization, the ecological environment has deteriorated in the world, how to effectively protect the natural resources has aroused people's attention. This paper reviewed the ecological benefits of forest assessment of the situation and development trend, focus on the ecological benefits of forest evaluation method and evaluation standards and the application in practice. Select the suitable way to laoshan forest ecological benefit evaluation, and according to the evaluation results on how to protect the function of forest ecological benefit, this paper puts forward the suggestions and countermeasures, the main research contents are as follows:1.Analysis the forest ecological service function and physical measurement methods, and sure this paper take the measure index, including water conservation and nurse protecting fertilizer, fixing carbon and releasing oxygen, and purify the air, adjust and maintain forest microclimate of biodiversity function. This paper describes the ecological functions of the calculation method and in combination with the social basis and laoshan forest environment, take the above indexes based on results of the ecological functions of forest benefit calculations, the quantitative calculation results provide the simulation analysis, provides the basis of comparison and analysis.2.This paper reviewed the research progress of adaptive management and the forest calculation method in the adaptive management mode of the ecological benefits, also reviewed the system dynamics, the development situation of system dynamics modeling process will be applied to the ecological benefits of forest, and the evaluation method of system dynamics software Vensim, and takes it as the main tools for simulation analysis of this paper.3.It simulated the development of the ecological benefits of laoshan farm from 1990 to 2010 by Vensim, and will be compared the simulation results with real situation, including the analysis of difference. It analysised the change of the ecological benefits of forest developments for laoshan farm from 2010 to 2016,compared the results to the simulation results from 1990 to 2010,and tried to explain the differences of them.4. Combined with the actual situation of forest laoshan and development goals, It put forward to the countermeasure and the suggestion for improving the ecological benefits of forest, including establishing perfect evaluation system; Improving overall detection level; Using the adaptive management mode, strengthening the control of the feedback part management; Increasing compensation standard, etc.
