CONSTRUCTION OF ECOLOGICAL EVALUATION SYSTEM FOR URBAN GREEN SPACE PLANNING

摘要

With acceleration of urbanisation process and continuous degeneration of urban environments in China, ecological values of urban green space system are becoming more and more important. Thus, to guarantee coordination between urban green space ecology and landscape functions, it is extremely essential to construct a more scientific, reasonable and operable urban green space eco-evaluation system. Through classified research and analysis of space construction as well as ecological functions of urban green space, this paper shall analyse the evaluation levels of urban green space eco- evaluation system from the perspective of urban planning, ecology, landscape, etc. what's more, it shall take 'Planning and Construction of Green Space System in Yuehe New City District' as the example to make a case study, analysing quantity, structure, function and quality of all indexes. Finally, it shall construct an urban green space eco-evaluation system with one destination layer, three second-level factor layers and fifteen third-level index layers as well as divide these fifteen indexes into 12 quantitative ones and 3 qualitative ones, in the hope that the system could help in monitoring urban green space construction quality and guiding reasonable construction.
