Abstract: Resources are basic requirements for the construction of ecocities and are important limitations for urban development. When making protective strategies for sustainable utilization of resources in constructing ecocity, the quantity of resources and the conflict between resource conditions and development of urban society and economy should be considered synthetically. Based on the profound connotation of ecocity, the scope on sustainable utilization of resources should be extended. People should focus on natural and biological resources, and also on human resources. We must pay adequate attention to cultures of a city by inheriting and protecting them in constructing ecocity. As a case, Changzhou was studied in relation to sustainable utilization of land, water resource, biological resources, and human resources, and a conceptual planning was established, which provided important guarantee for utilizing resource advantage to obtain its ecological and environmental benefits.

Key words: ecocity, sustainable utilization of resources, Changzhou City
