In this paper, favorable conditions and constraints for constructing an ecological city are analyzed and construction concepts are put forward. It contributes to the construction of Liaocheng into an ecological city and has a referential value for other cities.展开更多

Research background of livable city in China was elaborated from three aspects: accelerating urbanization, increasing city problems, the construction of livable city becoming a requirement of the times. Then the researches of livable city were overviewed from four aspects: concept and connotation, evaluation standard, evaluation method, organization and classification of the correlative references. And prospects of livable city researches were given.展开更多

Influence factors of urban village renovation were analyzed on the basis of brittleness theory, and an evaluation index system established through multi-level inconsistency decomposing. By incorporating the catastrophe theory with fuzzy mathematical theory, the mathematic model was created, and catastrophe membership function was obtained as well as evaluation results. Policies for the renovation of urban villages and new direction of the renovation were interpreted. The application case proved that catastrophe progression method was objective and effective and it could provide new concepts for the evaluation and adjustment of urban village renovation. Moreover, application of brittleness theory in the research on urban village renovation is of great instruction and reference value for the present urban construction.展开更多

Current researches on location of urban public facilities in China cover various aspects,involve different units,show diverse features,and make outstanding contributions. However,these researches have also obvious limitations. The future study on public facilities' location will focus on specifi c application of the model in different cities,or better consider characteristics of the city.展开更多
