| Based on the urban development theory, landscape ecology theory, urban recreation theory and urban green space system theory, this essay studies park green space system in urban planning areas in a systematic way, through adopting methods of qualitative and qnantitative analysis. It mainly focuses on layout planning and evaluation pattern and lays a theoretical foundation for building up a reasonable urban park green system, which is of great realistic significance.The findings of this research can be concluded as follows:1. It expands the definition of urban green space by bringing suburbs recreation area into urban park green system planning.2.It clarifies the classification of urban park green space, investigates on the configuration modes of park systems in different cities and comes to the conclusion that hierarchy configuration is the ideal mode.3. It establishes a park green space system evaluation mode made up of six components, namely, landscape pattern, park grading, recreational features, green structure, landscape benefits and evironmental benefits, and employs AHP(Analytic Hierarchy Process) to weigh its respective importance. As a result, park grading(0.3825) ranks the highest, then landscape pattern(0.2504) and recreational features(0.1596).4. The above mentioned layout planning and evaluation modes were applied to a case study of Deqing urban park green system. With emphasis on recreational features and landscape pattern, an empirical study of Deqing urban park green space system was carried out. To sum up, the existing problems are: not enough parks, unreasonal layout; monotonous parks, lack of diversity; park system inconsistency, no urban park corridor system; not including various new green space in suburb areas; underdevelopment of recreational features of urban park green space and etc.. Thus solutions to these problems were proposed accordingly in this essay from the perspectives of park green space system layout planning and park green space type system. |
