Comprehensive Benefit Analysis Of Guangxi Eucalyptus

Eucalyptus is one of the world’s top three fast-growing species.Eucalyptus plantation in Guangxi is the first eucalyptus plantation in China,and its planting area is the highest in China.And how to evaluate the comprehensive benefits of Eucalyptus plantations has become the focus of attention of ecologists and forestry workers.Based on the present situation of Eucalyptus in different regions of Guangxi,this paper analyzed the ecological,economic and social benefits of Eucalyptus,and using the analytic hierarchy process.Research indicates:1.In the paper,choose Eight typical representative Eucalyptus plantations were selected to analyze the development status of Eucalyptus plantation in Guangxi.In the analysis of economic benefits,combining Eucalyptus plantation economic distribution,Eucalyptus plantation economic structure analysis,Eucalyptus plantation development potential research and each index static and dynamic analysis,summed up the eucalyptus plantation economic benefit is better Guiyang City;in the analysis of annual investment profit rate,Wuzhou Eucalyptus Plantation net profit is the highest,followed by Yulin City,the annual investment profit rate reached 35.11%;asset-liability ratio and capital tax rate,Guigang City Eucalyptus plantation industry was higher than other areas,respectively 40.53%and 25.25%;in ecological benefit analysis,from the ecological value index evaluation,environmental factor index evaluation and ecological health assessment of three aspects,statistics obtained in Nanning,The ecological inputs of Yulin and Chongzuo were more than half of the total output value,which indirectly proved that the ecological input of Eucalyptus plantation was higher in these three areas.In the investigation of environmental restoration ability,the evaluation value of Eucalyptus Plantation in Nanning The highest,reaching 0.778;in the social benefit analysis,the social market efficiency and social benefit index analysis,and the investigation of eucalyptus plantation industry employment rate statistics,obtained in various regions of the employment rate of more than 50%,And the employment rate of Nanning was 87.32%.In the proportion of industrial staff,the proportion of Eucalyptus Plantation in Guigang City reached 80.55%,and the Eucalyptus Plantation in Nanning had the best social benefit.2.Eucalyptus plantation has the most important economic and ecological benefits,and the economic benefit of Eucalyptus plantation is the most important.In the validation of comprehensive benefit evaluation system of Eucalyptus plantation,the A-B layer with CI = 0.0091 and RI = 0.518 was obtained,and the multivariate analysis of A-Bi layer was carried out with CR = 0.0095,which was less than 0.1.The comprehensive evaluation index system of Eucalyptus plantation was established by using the three indexes of ecological,economic and social benefits,and adopting 30 indicators in 4 levels by AHP.The index of ecological,economic and social benefits in the standard layer are 0.275,0.461 and 0.188 respectively,and the economic benefit contribution index is the highest.In this paper,combined with the actual development of Eucalyptus plantation in Guangxi,combined with analytic hierarchy process analysis of evaluation data to expand the development of countermeasures,and to develop suitable for eucalyptus plantation sustainable development of the program strategy for the future development of eucalyptus in Guangxi provide a theoretical basis..
