Abstract

Take Hangzhou as an example, ecological safety evaluation of urban land provides the basis for promoting urban ecological security.21 indicators were chose to set up the evaluation system. By using BP neural network method, the study followed is trying to evaluate ecological security of urban land. The 2001 to 2007 data for all indicators as input nodes of neurons, the neural network training. Then enter the 2008-2010 data of the indicators, and finally get the sub-level of security evaluation results. And the result shows that the security level of Hangzhou’s in 2008 and 2009 are both , and its in 2010. Finally, BP neural network is able to achieve the purpose no evaluating the ecological security of urban land. And it takes an important part in exploring a new way for security of urban land as well.
