| With the increasing of urban population, urbanization accelerates rapidly around the world, especially in developing countries. The resulting problems caused by urbanization such as population expansion, spread of the severe pollution of the environment, expansion of city as well as urban layout problems is effecting the sustainable development of the city. The operation of urban green space results in improvements in urban residential environment, maintenance of the ecology, disaster preventions, improving and promote the city image and city skeletons etc. With the rapid development of economy and technology, urbanization processes has caused the speed up of serious ecological crisis, urban green space research development became more mature as people paid more attentions towards it. As a guide to urban green space development pattern of green space, the technical guidance effects the urban green space target positioning and development to implement. Through quantitative analysis, evaluation of the rapid urbanization area green space pattern and control research, as well as in the process of rapid urbanization of urban green space layout research has important reference value.By analyzing the relevant theoretical basis, using AHP establish matching factor evaluation system, Hefei Lakeside for the study, with the use of 2014 Lakeside Hefei aviation remote sensing image painted green translation of information, its pattern of green space Analysis and the status is evaluated. Lakeside Hefei systematic study plan and host profiles, explores the dynamic mechanism of urban green space development pattern, proposing green space planning concepts and rapid urbanization area regulation countermeasures. The main conclusions are:(1) According to the existing relevant index system, using analytic hierarchy process and comprehensive evaluation method to establish evaluation model for green research status, and through expert evaluation score to get results. The evaluation results show that the spatial pattern of Hefei Lakeside green composite scores 8.0836(excellent), parkland scores 8.33695(excellent), production green scores 4.99088(medium), protective green scores 6.4451(good), a subsidiary green scores 8.00185( excellent), ecological green scores 7.31456(good).(2) The driving force of The Hefei Binhu new area green space pattern of the development are political factors, the common result of economic development and social factors. The development of green space layout has good foundation of the advantage of local policy support, the environment, planning guidance and public participation as well as the tourism culture industry to improve the efficiency; The disadvantage are the contradictions between urban construction and ecological protection, the contradictions between construction and management of maintenance, new city green space function relationship between urban land and out of line and so on.(3) In the regulation of research on rapid urbanization pattern of green space to system integrity, ecological balance, spatial and temporal continuity, construction and management of a combination of the overall planning concept, determine the total amount control, quality control, connectivity control, functional regulation countermeasures. Lakeside Hefei proposed green space structure of "green veins" and "blue veins", "context" of the main line, specifically the formation of "symbiotic Lake City, as one two, two with four gallery, green network coverage, multi-point mosaic" of space pattern of development. |
