| Classified management of the state-owned forest farms is an important principle of the reform of the state-owned forest farms, scientific classification is the basis of the classified management, the research on classification of the state-owned forest farms has great realistic significance. Firstly, according to the "National Plan for Development Priority Zones", the paper partitioned the state-owned forest farms partition into the state-owned forest farms in prohibited zone, the state-owned forest farms in key ecological function zone and the state-owned forest farms in the general function zone. Secondly, in the method application, the paper designed the classification index system design of the state-owned forest farms based on correlation analysis and principal component analysis. Thirdly, using the methods of cluster analysis and cluster validation, the paper established the classification model of the state-owned forest farms, the state-owned forest farms in prohibited zone were classified into ecological steady, ecologically fragile and ecological weak farms, the state-owned forest farms in key ecological function zone were classified into ecological public benefit farms and ecological management farms, the state-owned forest farms in the general function zone were classified into ecological public benefit farms,ecological management farms and commodity management farms. Finally, the paper put forward the management suggestion to the various types of state-owned forest farms.The management of the state-owned forest farms should actively introduce market participation, separate the management and administrative rights and establish perfomiance appraisal system with forest resources quality and operating conditions as the core. The state-owned forest farms in prohibited zone or the ecological public benefit farms should aim at improving the quality of forest resources and playing the ecological benefits. The main source of their funds should be finance investment, the allocation of the funds should be used in improving forest resources management and employee benefits. The ecological management farms can carry out non-expendable use and strengthen the ability of independent income generation under the premise that they can ensure the quality of forest resources and meet the ecological requirements of each functional area. For commodity management farms, we encourage their utilization of forest resources while playing ecological benefits. The main source of their funds should be self-funding and financial investment play a supplement, the capital allocation adapt the form of "pays taxes +own allocation". |
