- Abstract:
- Aiming at the ecological sensitivity risk caused by the evolution of the ecological landscape pattern of the Tibet Plateau, taking the Nyang River Basin in the ecologically fragile area of the Tibet Plateau as the research object, based on the four periods of land use data in 1980, 1995, 2010 and 2020, quantitative analysis of the changes in land use structure and transformation characteristics of the Nyang River Basin in the past 40 years, the theory of landscape ecology, we divided Nyang River Basin into 814 ecological risk assessment units, constructed a landscape ecological risk assessment model, and quantitatively evaluated the spatial and temporal dynamic evolution characteristics of landscape ecological risks in the Nyang River Basin. The results show that:(1)the area of the six land use types in the Nyang River Basin has changed in the past 40 years, of which the water area and construction land has changed the most;(2)the area with high ecological risk and medium ecological risk in the basin from 1980 to 2020 increased, and the overall landscape ecological risk in the basin was increasing; the areas of ecological deterioration mainly occurred in the valley area of the Nyang River and high-altitude areas; the ecological risk levels of the Nyang River Basin in each period were based on the Nyang River as the axis presented a symmetrical distribution, and the ecological risk level increased with the increase in altitude;(3)the spatial distribution of landscape ecological risk in the Nyang River Basin was positively correlated year by year, which manifested as an agglomeration effect in space. From 1980 to 2020, the ecological risk of the Nyang River Basin rose. Human activities and climate change are important factors driving the ecological deterioration.
