Speaking from the origin, the urban green space system is a product of the industrial revolution, with the generation of urban environmental problems and people feel out of natural pain. Urban green space and urban green space system formed by the organic links, the main venue of the urban residents in touch with nature, with its diverse functions, is becoming more and more important in the urban construction. Urban green space system planning in China has also been unprecedented attention, regulations and norms were introduced. However, the scientific preparation of urban green space system planning, inseparable from the urban green space system planning evaluation; want scientific evaluation of urban green space system planning, it is necessary to carry out research on the evaluation of urban green space system planning, to the establishment of urban green space system planning evaluation systems. This is the practical significance of the research. Use \First defined the concept of urban green space, urban green space, urban green space system planning and evaluation of its evaluation system of the urban green space system planning; elaborated on this basis, the concept and content of the evaluation criteria; functions of urban green space system planning theory structural elements, layout principles and mode, planning content and standards, as well as trends collated. Then the status quo was the evaluation of urban green space system planning, and pointed out that the main problem there. Determine ways and unified evaluation of content, in order to function as a unified evaluation criteria, unified evaluation method, unified evaluation grade standards of the ideas in the construction of the evaluation system of the urban green space system planning. The domestic situation on the basis of clear evaluation system to solve the main problem, research from the overall structure, elements of urban green space system, established 16 evaluation indicators and evaluation criteria, evaluation methods, the evaluation results grade standards, build the evaluation system of the urban green space system planning. The combination of last instance, the use of the evaluation system, evaluation of Yiyang City Green Space System Planning, evaluation results are obtained, and Yiyang urban green space system planning optimization recommendations. In this paper, the main problems in the urban green space system planning and evaluation, comprehensive theoretical study and construct its evaluation system, in order to have some practical significance.
