As a key food production base, land use changes in the Jianghan Plain (JHP) significantly affect surface landscape structure and ecological risks, posing challenges to security. Assessing risk of JHP, identifying its drivers, predicting trends under different scenarios can provide strategic support for management safeguarding security JHP. In this study, (LER) index was constructed by integrating indices from 2000 2020, firstly analyzing spatiotemporal characteristics, subsequently influencing factors using GeoDetector model, finally, simulating four Markov-PLUS model. The results showed that: (1) Cropland dominant use, most significant decreases increases occurred cropland built-up land, respectively. primary conversion interconversion water body. (2) LER exhibited trend initially increasing decreasing, levels were predominantly medium higher. spatial pattern high southeast low central northern areas. (3) patterns resulted combined effect multiple mainly influenced natural environment, which NDVI first factor. (4) intensity higher economic development than protection scenarios, predicted 2030 former latter two. These findings are important formulating scientific reasonable planning strategies balance growth preservation maintain sustainability

Ecological Waves at Tourist Attractions on the Qinghai-Tibet Plateau Promote Greenness of Surrounding Vegetation

Land, Год журнала: 2025, Номер 14(1), С. 159 - 159

The unique tourism resources of the Qinghai-Tibet Plateau have created conditions for development ecotourism, while existence attractions may also positive and negative impacts on surrounding environment. This study defines radiation waves that generate ecological effects as “ecological waves”, quantifies by buffer zone analysis normalized difference vegetation index (NDVI) within 20 km 38 4A 5A in 2020, elaborately explores By combining principle ripple effects, it analyzes impact urban environments. found a effect vegetation, suburban has distance threshold, effectively promoting greenness range 6–14 km, disappears beyond 14 km. In addition, applying model to city centers (Xining Lhasa), results indicated among five Xining, Kumbum Monastery, Qinghai Tibetan Culture Center, Country Farming Ecological Park (with restrictions 2–20 km) significant built-up area, Province Museum Qinghai-Tibetan Safari are not significant. Lhasa area significant, different thresholds effects. Furthermore, this better foundation around them than Tibet, making more suitable ecotourism. opened up new perspective provided scientific references Plateau.
