Article analysis:
The article appears to be reliable and trustworthy as it provides a comprehensive evaluation of the ecological security of Jiuzhaigou Nature Reserve over the past 20 years. It uses a well-established model (PSR) and barrier factor analysis to assess the situation, which adds credibility to its findings. Furthermore, it provides detailed information on potential obstacles to ecological security such as population growth rate, number of geological disasters, and legal perfection degree.
However, there are some potential biases that should be noted. For example, while it does provide an overview of potential risks associated with human activities in the area, it does not explore counterarguments or present both sides equally. Additionally, there is no discussion about possible solutions or strategies for mitigating these risks or improving ecological security in general. Finally, there is no mention of any promotional content or partiality in reporting which could potentially influence readers’ opinions on this topic.
