The Evolution Of Management Ideas About Urban Forestry And The Impact On The Green GDP

Urban forestry is an safe and effective means to solve the problem of urban environmental pollution, ecological imbalance and it plays an increasing import -ant role in achieving urban sustainable development, reflects the degree of sustain–able urban development. In this paper, the history of literature, humanistic approach, structure - activity analysis method and comparison methods can be found, to explore the concept of urban forestry; examines the evolution of management ideas of urban forestry and its impact on green GDP; analysis the obstacles and strategy in Chinese urban forestry management and figure out the new accounting paradigm of green GDP. In the process, the urban forestry concept analysis framework, the function indicators system of urban forestry, and the new model of green GDP accounting are to be built, and the future development trend of urban forestry is to be discussed.Conclusion comes like this after the comparative analysis of the structural decomposition: with its natural functioning and utilization of the property, urban forestry is an industry which meets the economic, social, ecological and other comprehensive needs of the society, which is different from the natural forest. Urban forestry has a natural-social dual property. It is constrained by the golden law and the demands of the cities. From the industrial point of view, urban forestry is the first and tertiary industries. It is an important facilities and an integral part of the city to improve the development of the city on ecological and social services. The nature of its object of study says that urban forestry is not a branch of forestry, but a specialized independent discipline.According to the way of utilization of urban forest functions, after contrast studies, the function of urban forest products is itemized as follows: economic output functions, ecological product output function, social output function and plant caused pollution. Indicators of urban forest functional features are different with ones of others forests, which is decided by the social attributes of urban forestry. The distance is the most influential factor. The urban forest is so close to the city. With the frequency of exposure, some of its effects are more significant than those of other forests, such as plant caused pollution. Other forest as far away from people, this feature is not that obvious; especially the social benefits due to human subjectivity, such as the role of urban forest recreation, entertainment and other functions ect. Other forest (except for tourist attractions) are far away from the city, barely have no such features.Historical documents and other humanistic analysis on Evolution of urban forestry management were studied. Business ideas of the urban forestry are evolving with the social values in social changes, and changes in social attitudes is determined stage of social development, that is, business ideas of urban forestry with the development of society was spiraling. This evolution has always been taking around the changing of the needs of the urban forestry. Content and methods of urban forest management are changing correspondingly. Urban forestry and its management are divided into 5 parts: the original era, the ancient era, horticulture era, era of parks and era of knowledge. The law of evolution on urban forestry business ideas has great significance to our current urban forestry management. It indicates that urban forestry management should evolve with the development and the actual situation of the society.Discuss the impact of green GDP which is led by the changing of objectives of urban forestry management between material and non-material. Studies suggest that the changes of people's need of urban forestry management lead to the changes in the value and the accounting method of urban forestry ,then makes the evolution of urban forestry management, as a result, the whole GDP system, such as "scientific" thinking, accounting content, accounting paradigm has a comprehensive and profound effects: provides a historical basis with green GDP's "scientific"; further improve the idea of Green GDP; enriched the accounting content and indicators of the green GDP; re-defining the green GDP accounting procedures and formulas and other paradigm. And in the study, take the urban forest of green GDP accounting for example, demonstrate all of those impact.Through the evolution of urban forestry research thinking, this paper forecasts the development trend of urban forestry, the goal of which is mainly to meet people's needs and diversity of knowledge value. In this goal oriented, urban forestry will be to the art, high-tech direction. Molecular biology, genetic engineering, 3S, information databases and a series of advanced technologies and tools will be applied to the management of urban forestry. Urban Forestry will also be the subject of change with biological gene technology, efficiency in the resilience of urban forestry, develop new features will be heard, and 3S technology, database and other advanced technological tools to the Urban Forestry management applications in the study will also be extensively carried off.The obstacle and the strategy of Chinese urban forestry management is analyzed. The obstacles include: land resources, especially arable land resources are very limited, as a result the urban forestry land severely restricted; per capita is still relatively backward economic development, and the government funding is less; local government does not attach importance to the management of urban forestry by the impact of cultural traditions, political institutions and lack of public supervision; the technology theory is less developed. So the measures include: carrying out functional zoning, classification management to enhance the effect of urban forest management; based on principles of ecology related to the space to be effective, space-exchange area; Make the green GDP as the assessment of official standards, while increase public awareness of environmental protection and strengthen public oversight; established of specialized urban forestry management company which is led by the government to carry out urban forestry products to be market-oriented operation according to market allocation rules, to improve social capital in urban forestry management initiative.
