abstract = {【Objective】Ecological security is an important part of national security and an important guarantee for the sustainable and healthy development of economy and society. Constructing the landscape ecological security pattern of forest parks and exploring its obstacle factors can provide reference for the sustainable development of China’s ecosystem.【Method】The evaluation index system of landscape ecological security of forest parks was constructed from three sub-target layers of pressure, bearing capacity and maintenance capacity. Taking Baiyun mountain national forest park in Henan Province as a sample, 2013-2022 as the research period, the entropy weight TOPSIS method was used to measure the landscape ecological security level of Baiyun mountain national forest park in Henan Province, and the obstacle degree analysis was further used to indicate its influencing factors.【Result】The five indicators of population density, natural disaster area, broadband greenness index, Shannon-Wiener index and government forestry investment intensity have higher weights in the evaluation index system of forest park landscape ecological security. During the study period, the landscape ecological security level of Baiyun mountain national forest park in Henan Province showed a fluctuating upward trend; from the analysis of the sub-target layer score, it can be seen that the average annual growth rate is ranked as maintenance force > bearing capacity > pressure. During the study period, the relative closeness of the three sub-target layers showed an increasing trend year by year, while the obstacle degree showed a decreasing trend year by year, and the sub-target with the largest obstacle degree was the pressure layer.【Conclusion】Based on the results of landscape ecological security evaluation of Baiyun mountain national forest park in Henan Province, some suggestions were put forward to improve vegetation richness, continuously improve species diversity and strengthen forestry investment intensity, so as to promote the safe and sustainable development of ecological system.}
