- W2979799445 abstract "The accurate control of the degree of land development and the objective assessment of current land ecology are important issues that human beings must consider. Taking Henan province as the research area, this paper uses the Driver-Pressure-State-Impacts-Response (DPSIR) conceptual model to establish an assessment index system of land ecological security, and employs the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) assessment model to evaluate the land ecological security of Henan province from 2007 to 2017. The assessment results show that the land ecological security value of Henan province is generally continuously improving in 2007-2017 (from 0.5640 in 2007 to 0.6512 in 2017), but there were minor fluctuations in 2009, 2013 and 2016. In 2012, the land ecological security level starts to improve from a critically secure state to a secure state. Finally, according to the evaluation results and the actual situation of Henan province, specific countermeasures are put forward from the three main factors that cause the low value of land ecological security: state, response and pressure." @default.
