【Abstract】 Based on the PSR model,the land ecological security evaluation system of Lianyungang city was constructed from three aspects of pressure,state and response.The land ecological security of Lianyungang from 2000 to 2016 was evaluated and analyzed by matter element analysis.The results showed that the level of land ecological security in Lianyungang city increased from "unsafe" to "safer" during the research period,and the overall security level tended to be better,but it was in a "safer" state of instability,and the situation of land ecological security was not optimistic.更多还原
