Study On The Sustainable Development Of Forest Ecological-economic System In Changhua River Basin

Forest ecological and economic systems are the main study object of forest eco-economic system, and how to configure the ecological, economic and social resources is the focus study of the forest ecological and economic sustainable development. Watershed forest ecological and economic sustainable development evaluation is base on the theory of sustainable development, ecology, regional economics and management science, and analysis of the status of forest resources, economic conditions and social development in the watered, and establish the goal of sustainable development of the watershed forest ecological and economic systems and sustainable development criteria. On this basis, it can build a sustainable development index system and evaluation methods in accordance with the principles of ecological, economic and social development. This paper carry out three aspects for the Changhua River Basin forest ecological and economic status quo, business models and existing problems. The sustainable development of the evaluation index system establishment and evaluation methods research of Changhua River Basin, analysis of eco-economic disparities Changhua River basin, and the dynamic analysis of Changhua River Basin sustainable development. The results show that:Firstly, establish the system of indicators for sustainable development of the Changhua River Basin. According to economic studies of forest ecosystems at home and abroad, combined with the Changhua River basin characteristics, propose three of the ecological, economic and social support subsystem,16individual indicators of the index system. Select entropy method in determining the weights, to amend the results to eliminate the bias caused by subjective factors. Accordingly, research on the Changhua River basin forest eco-economic system, the results shows that:Economic subsystem for building and sustainable development of ecological economic system has made a significant contribution to the weights as high as0.5164. Followed by the social subsystem, the weight value is0.2629, In contrast, the ecological subsystem Changhua River basin eco-economic development cause obstruction, only0.2206of the weight values; According to the analysis of the indicator layer, make the greatest contribution to the ecological and economic development indicators of index of GDP in the economic subsystem, the weight is0.0925. the forest coverage rate of the Valley Economic Development, the weight is0.0871. Social subsystem of education index weight values in the index layer of the middle reaches, and that education has become an important factor of economic development. On the contrary, forestry output value of weight is the lowest, only0.0402, the convection within the eco-economic development hindered, shows that the role of forestry in the development of the basin does not have good guidance; its function has not been exploited.Secondly,The paper introduces the concept of convection within the eco-economic development of the spatial differences the current situation analysis. Study because of the impact basin on the middle and lower reaches of the differences of the ecological economic development on the Changhua River Basin Sustainable Development. According to the value of comprehensive evaluation of the Changhua River Basin to determine the spatial difference of values that Changhua River watershed ecological spatial pattern of economic development is high, the upstream, midstream second son, downstream of the lowest. Ecological and economic development gap between the level on the middle and lower reaches of the watershed. Spatial differences within the watershed were negatively correlated with the ecological subsystem, economic subsystem, social subsystem was positively correlated, and Subsystem of the economy played an important guiding role in the comprehensive evaluation. Using GIS technology to study the difference of the Changhua River watershed ecological and economic space is one of the trends in the field of regional economic research, Using GIS technology can visual representation of the spatial differences within the watershed.Thirdly,2006-2010, Changhua River Basin Sustainable Development coefficient showing an increasing trend, an upward trend in volatility. According to the data dynamic analysis, Sustainable development coefficient of the upstream region is the highest; the downstream region is the lowest. From the changes of the three subsystems, Changhua River watershed ecological and economic effectiveness of the system significantly, and supportive of the ecological environment, stable economic development have good sustainability, increasing year by year. Dynamic analysis showed that the Changhua River basin sustainable development situation is gradually improving, Embodies the Changhua River Basin Sustainable Development Policy in the gradual implementation of the watershed Neisen ecological and economic system gradually become coordinated development.Fourthly, by analogy, This article has made new progress in the top of the Changhua River Basin forest ecological and economic sustainable development of the evaluation index system and evaluation method, Combined with the analysis of spatial differences on the watershed, provide a theoretical basis and data facts for Changhua River Basin Sustainable Development policy-making in the future, and make great significance for watershed development in future.
