Theory and method of urban landscape ecological planning based on complexity theory

Yanyan Cheng

Many cities face a series of so-calledcity diseasessuch as traffic jam, housing problems and environmental pollution as economy has developed and cities have expanded rapidly. In this paper, based on the discussion on the theory of restoration ecology and landscape ecology of urban green space system planning, according to the need of economic development and the results of the above research, the framework and measures of urban green space system planning was proposed. Based on the complexity characteristics of urban ecosystem, the systematical theory and ecology, assessment and planning of urban ecosystem were developed. Thisstudy has been helpful to develop ecosystem modeling based on complexity theory and further improve cognition to the development law of urban ecosystem. Moreover, the complexity theory could more accurately and effectively account for the complex behaviors of urban ecosystem, and promote the sustainable development of urban ecosystem more effectively.
