Tourism Ecological Security Assessment and Its Driving Mechanisms in Anhui Province: An Integrated DPSIR– SBM-DEA Framework
This study evaluates the spatiotemporal evolution and driving mechanisms of tourism ecological security across 16 prefecture-level cities in Anhui Province from 2008 to 2019 using an integrated DPSIR–SBM-DEA framework, revealing a fluctuating upward trend with a distinct "high-south, low-north" spatial pattern driven by factors such as tourist arrivals, population density, and environmental indicators.

Imagine the Earth as a giant, complex video game world where every player (us) leaves footprints. Sometimes we build cool cities and trade goods, but sometimes we trample the grass, pollute the rivers, and make the air hard to breathe. Scientists call this balance "ecological security"—basically, checking if the game world is still healthy enough to keep playing without crashing. In this story, we aren't looking at the whole world, but at a specific province in China called Anhui, which is famous for its beautiful mountains and ancient villages. To understand how tourism (people visiting for fun) affects this "game world," the researchers used a special toolkit. They combined a "cause-and-effect" map called DPSIR (which tracks how our actions lead to problems and then to fixes) with a "scorecard" system called SBM-DEA (which measures how efficiently a place uses its resources without breaking them). They also used satellite eyes to take pictures of the greenery and water, and some math tricks to see if the changes were real or just random noise.
So, what did the team from Yili Normal University actually find when they looked at Anhui's tourism between 2008 and 2019? Think of Anhui's tourism health as a rollercoaster that started with a scary drop, wobbled a bit, and then slowly climbed to a higher, smoother track. The researchers discovered that while the number of visitors and the pressure on the land were increasing, the overall "ecological security" score actually went up. It wasn't a straight line up, though; it had a few dips, especially around 2009 and 2013, before settling into a steady, high-level groove after 2015.
The map of this health score looks like a game of hot and cold spots. The southern part of the province, with its famous mountains like Huangshan, and the central-eastern areas like Hefei, turned into "hot spots" of high ecological security. These areas are like the VIP zones where the scenery is lush, the hotels are great, and the environment is well-protected. In contrast, the northern parts, including cities like Bengbu, remained "cold spots," where the ecological security was lower, likely because of denser populations and less green cover. The study suggests that this isn't just random; it's a pattern where the south and center-east are winning the green game, while the north is still catching up.
What made the difference? The researchers used a digital detective tool called the Geo-Detector to figure out which factors were pulling the strings. They found that the biggest drivers were the number of people visiting (tourist arrivals), how crowded the cities were (population density), and how green the land looked from space (a measure called NDVI). It turns out that having more tourists and more people living there puts a heavy load on the system, but having more green plants and better government spending on waste treatment helps pull the score back up. The study didn't find that tourism automatically destroys nature; instead, it showed that if you manage the pressure (like water use and crowd control) and boost the response (like cleaning up trash and funding parks), you can have a booming tourism industry without ruining the ecosystem.
In short, the paper suggests that Anhui is learning to play the "tourism game" better over time. By 2019, the province had moved from a state of fluctuating stress to a more stable, high-security zone, proving that with the right mix of green policies and smart management, you can keep the tourists happy and the mountains green at the same time. The authors are careful to note that this is based on data up to 2019, before the global pandemic changed everything, so it's a snapshot of a specific era of growth. But the lesson remains: if you watch your footprints and fix the holes you make, the game world stays safe for everyone.
