Abstract: In order to understand the status of land eco-security of Sichuan Province, evaluation index system based on P-S-R model was built, land eco-security of 18 cities in Sichuan Province was evaluated with the method of entropy weight and matter element. The results showed that: the land eco-security level of Chengdu was “criticality safety”, the land eco-security level of Zigong, Luzhou, Guangyuan, Neijiang and Dazhou transformed to “safety”, the land eco-security level of Panzhihua, Deyang, Mianyang, Suining, Leshan, Nanchong, Meishan, Yibin, Bazhong and Ziyang transformed to “safer”, the land eco-security level of Guangan and Yaan transformed to “less safe”. Combined with single index correlation degree and comprehensive correlation degree, land eco-security of every city of Sichuan Province tended to be good.
