- Abstract
In order to correctly evaluate the ecological security of cultivated land in the main grain producing areas of Liaoning Province in recent years, this paper takes Tieling City as an example and uses the PSR evaluation model to dynamically study the ecological security of cultivated land in the whole city. Based on the actual situation, 12 indicator factors were scientifically selected to construct an evaluation indicator system, and the weights of each indicator were determined using the combination weighting method. The weighted TOPSIS model was used to calculate and scientifically analyze the ecological security dynamics of cultivated land in Tieling City from 2014 to 2021. From 2014 to 2021, the ecological security of cultivated land in Tieling City showed significant fluctuations but an overall positive development trend. The dynamic changes in cultivated land ecological security in Tieling City are closely related to the overall economic development of the city. The cultivated land ecological security level of the pressure and response subsystem still needs to be improved.
