Abstract:: Based on a pressure-status-response (PSR) model, the evaluation index system of land ecological security early-warning was built. And then the entropy weight and RBF model were used to evaluate and make a prediction for land ecological security development trend of Guangdong Province, meanwhile the spatial variation of eco-security in Guangdong Province in 2012 was analyzed. The results are shown as follows: (1) the comprehensive land ecological security index showed the rising trend with fluctuations, and remained in the heavy warning from 2000 to 2006, in the high warning from 2007 to 2009, in the moderate warning from 2010 to 2012, if the serious event didn’t existed, comprehensive land ecological security index would keep the same development trend, and still in the moderate warning from 2013 to 2016; (2) the spatial variation of eco-security in 2012 in Guangdong Province showed that the warning degree was high in the northern and western areas of Guangdong Province, and the eastern area and Pearl River Delta were lower than the northern and western areas; (3) the main factors influencing the land ecological security of Guangdong Province include the proportion of natural disaster-affected area, road density, the proportion of built-up urban area, per capita GDP, economic density, per capita net income of farmers, the proportion of nature reserves, which will be the focus of land ecological security regulation in the future.
