Benefit Combination Evaluation Research For Conversion Of Cropland To Forest Program In Southern China

The Conversion of Cropland to Forest Program is a major ecological construction project which has the widest scope,the largest investment, the most task and the highest public participation since the founding of new China. However, What level is the Conversion of Cropland to Forest Program construction in? What influence has the Conversion of Cropland to Forest Program on the area? How to draw up the subsequent policy of the Conversion of Cropland to Forest Program? All these problems are dependent on the benefit evaluation of the Conversion of Cropland to Forest Program. Many experts and scholars have studied the project benefit and obtained some achievements. However, no system study, no perfectful index system,no consistent and scientific evaluation methods restrict the practical significance of the Conversion of Cropland to Forest Program benefit evaluation activities.Therefore,based on current benefit evaluation research results, the comprehensive benefit evaluation index system of the Conversion of Cropland to Forest Program is established. In order to improve the credibility and accuracy of evaluation results,the combination evaluation method is introduced into the evaluation and the comprehensive benefit combination evaluation model is established. The benefit of ten typical counties in Southern China is evaluated according to the combination evaluation method. On the basis of evaluation research, policy suggestions are put forward to provide scientific basis for sustainable and healthy development of the Conversion of Cropland to Forest Program and perfect the relevant policy. The main research contents are as follows:Firstly,the comprehensive benefit evaluation index system of the Conversion of Cropland to Forest Program is established. According to the construction principles of evaluation index system, under the guidance of theory and practice,by means of the in-depth understanding of the Conversion of Cropland to Forest Program, the benefit evaluation index system of the Conversion of Cropland to Forest Program is established according to four steps of the building of the overall framework, theoretically preliminary selection,expert selection of the index system, establishment of the index system. The index system has four levels including the target layer, system layer, state layer and index layer and has a total of20indexes.Secondly,the combination evaluation method is applied to establish the comprehensive benefit evaluation model of the Conversion of Cropland to Forest Program. A lot of single evaluation methods are studied in-depthly. The characteristics and applicability of single evaluation method is compared. And then four single evaluation methods in this paper are determined. Through a large number of Chinese and foreign literature, the research content and status of combination evaluation is reviewed, the advantages and disadvantages and applicability of some common combination evaluation methods are compared, average combination evaluation model is constructed. A relatively perfect combination evaluation theory system is built.Thirdly, combination evaluation empirical analysis of the benefit of the Conversion of Cropland to Forest Program is conducted. Supported by State Forestry Administration forestry public welfare industry scientific research special funds project-benefit monitoring and evaluation research of CCFP in South China (item number-201004018) according to the vegetation and forest survey, soil survey,forest hydrological survey,construction planning data,statistical data,implementation plans,conclusion material,scientif research achievements are collected,related statistical yearbooks are consulted,The Conversion of Cropland to Forest Program benefit of ten typical counties in Southern China is evaluated according to the combination evaluation method from the static,dynamic angle and comprehensive, detailed angle. Combination evaluation scores and ranking of ten typical counties are obtained.The benefit development and change trend of ten typical counties in recent five years are analyzed.Empirical research is helpful to the correct evaluation of the current situation and potential with the typical counties, to understand the development trend of the counties,to perfect policy, to promote mutually and develop commonly between counties,to realize the healthy development of the Conversion of Cropland to Forest Program.Fourthly,on the basis of evaluation research, suggestions are put forward to improve the benefit of the Conversion of Cropland to Forest Program,to promote the ecological, economic and social harmonious development of the area.
