Abstract

In order to understand the status of cultivated land ecological security in the counties and districts of Eastern Liaoning, and provide theoretical basis and Countermeasures for the local government to formulate policies to protect cultivated land security, the PSR model was used to construct the index system of cultivated land ecological security, and the multi-factor comprehensive evaluation method was used to evaluate the status of cultivated land ecological security in eastern Liaoning. The results show that from 2005 to 2015, the ecological security index of cultivated land in Tieling, Dashiqiao, Kaiyuan, Fushun and Xifeng is relatively stable, and the ecological environment of cultivated land remains relatively good, while the ecological security index of cultivated land in the two counties of Bayuquan and Ganjingzi has been very low. Most of the counties and cities in eastern Liaoning have improved the ecological security of cultivated land. The security status of eight counties and districts is relatively stable and unchanged. The ecological security of cultivated land in 15 counties and districts has been improved. The ecological security of cultivated land in Ganjingzi has been in an unsafe state, which requires the government to take more effective measures to control it.
