Abstract

This study has been performed in order to analyze the coordinated degree and evolving trends of the land intensive use and land eco-security based on the statistical data from 1998 to 2007 in Chengdu city by Synergetios theory and dynamic coordinated degrees model. Results show that during the study period, the level of land intensive use and land ecological security both rose in Chengdu, the former continuing to raise, the overall increasing but some fluctuations in the latter. Dynamic coordinated degree in 10 years is between 8.99°~57.71° with a trend of rising firstly then dropping, undergoing the process from a relatively harmonious development to the best coordinated development, then to less coordinated development. From 2005, the coordinated degree between the two systems began to decline.
