This study describes the value of domestic and urban forest and its research status, based on the theory of value in the evaluation of urban forest resource values ??for the use of research and analysis, the paper select the range of built-up areas Zhoukou research areas to Zhoukou City Forest Resources for the study, the main use of Zhoukou City in 2007 Seventh forest inventory data, in 2008 the first time Zhoukou City green space and 2009 survey data Zhoukou City Construction statistics annual reports and other information, the application of RS, GIS and GPS technology using field survey data to correct interpretation of satellite images, the use of urban forest assessment of the value of learning evaluation methods, the study of the value of urban forest in the region's economic value, social value and ecological value of three aspects of the value of a comprehensive evaluation, and a development phase adjustment coefficient to obtain the final result. Using Excel software to analyze the results, by applying the theories and methods of the study conducted, to obtain a certain result. Zhoukou City Forest has enormous economic, social and ecological benefits, annual output value of 3,923,079,100 yuan, mainly the economic value of urban forest, accounting for 84.48%. The current value of these great benefits are not included in the forest of national accounts series being the need to take a scientific approach to internalize these external benefits. We took a 5% discount rate used for discounting and development phase coefficients adjusted Zhoukou City in 2009 present value of forest value 4,479,387,900 yuan, of which the economic value of 3,855,078,500 yuan, accounting for 84.48%; ecological value of 660,250,500 yuan , accounting for 14.47%; social value of 48.0438 million yuan, accounting for 1.05%. Economic value of the land value and is very prominent, there are 3,774,278,600 yuan, accounting for 84.7% is 5.35 times the value of the other. Ecological value and social value and is 7.73 times the value of the trees. SO2 removal is the least value of 1.8676 million yuan, accounting for only 0.042%. From the value of the component weightings of view, the economic value of forest land accounts for nearly 84.26% of the proportion of other values ??only 15.74%. In the economic value, the green value of the share would be quite high, accounting for the economic value of 97.90%; in social values, the value of forest recreation accounted for 9.08 percent, providing employment to 90.92%; ecological value, the value accounted for sterilization 57.36%, 19.12% noise reduction value, blocking dust value of 17.00%, 2.37% and soil conservation, carbon sequestration and oxygen was 3.87%, the proportion of removal of SO2 least 0.28%. The value of Zhoukou city forest dependent and have large differences in the value of sub-features. Quantity and quality of urban forest itself has a decisive role in its value. On the other hand, urban forest value evaluation is also affected by the price on the market and people's ability to pay and environmental impact of cognitive ability. The results have strong policy implications for urban forest to establish the correct values, perceptions Zhoukou City urban forest contribution to the development of the local economy, and promote the coordinated development of urban forests and to achieve sustainable economic development Zhoukou City has important practical significance.
