摘要：Nowadays, city planning with the core of smart growth has attracted more and more attention all over the world. In order to cope with the rapid development of world urbanization, America first adopted the "smart growth" strategy and proposesed ten principles of smart growth to curb the spread of cities, thus building a sustainable development city with economic prosperity, social justice and environment sustainability. This article combines four important indicators of geographical, environmental, social and economic conditions to establish an indicator system for evaluating the sustainability of the city based on the ten principles and 3E index. This article selects two places San Diego, USA and Adelaide, Australia to be the research object. According to the index system model, we evaluate the current growth plan. We use the entropy evaluation method to calculate the weight of each indicator of the city. The factors weight of San Diego were 0.308; 0.271; 0.172; 0.249 in economy, society, environment and geography, respectively. The factors weight of Adelaide are 0.310; 0.288; 0.230; 0.172 in economy, society, environment and geography, respectively. The entropy evaluation method and fuzzy comprehensive evaluation are used to assess whether the city meets the requirement of smart growth. The result shows that, the coordination coefficient of the two cities gradually reduced after 2016 which are going to toward the unsustainable development. Based on the smart growth evaluation index system and optimized urban plan combined with the time series, we predict the data from 2016 to 2050 and evaluate the future development of the two cities through the entropy method. As a result, the two cities-San Diego and Adelaide are sustainable development cities which conform to the principles of smart growth.
