From the perspective of ecological city framework and ecological planning, and through analysis of issues pertaining to ecology, urban design, urban park and environmental planning, this study identifies 30 principles for ecological planning of urban parks including conceptual, survey, analysis/evaluation, management and maintenance, and educational explanation aspects. Items 1~6 form the conceptual dimension; items 7~8 form the survey dimension; items 9~15 form the analysis/evaluation dimension; items 16~27 form the planning dimension; items 28~29 form the educational explanation dimension; item 30 forms the management and maintenance dimension. At present, most of the planning and management of urban parks is based on landscape and recreational perspectives. Ecology-based discussions are rare. It is the author’s hope that the principles identified above can serve as reference for concerned agencies in their future planning and design undertakings in order to alleviate the impact of park development on the ecology, enhance the possibility of biological diversity, and realize the goal of building sustainable ecological cities where mankind and other living creatures can co-exist in peace.
