Regions in which eco-environmental quality has been degraded by unreasonable land use are urgent to optimize land use management.Ībdalla M, Saunders M, Hastings A et al (2013) Simulating the impacts of land use in northwest Europe on net ecosystem exchange (NEE): the role of arable ecosystems, grasslands and forest plantations in climate change mitigation. The results indicated that under the influence of climate change, the changes in land use and eco-environmental quality were inconsistent in part regions, mainly including the central and southern Tibet and the border zone. Conversely, the expansion of built-up land and land degradation contributed to decline in local eco-environmental quality in the Hengduan Mountains, northeastern plateau, and Qaidam Basin. The improvement in eco-environmental quality attributed to land use change was mainly due to the conversion of unused land into grassland, and ecological conservation projects also improved the local ecological environment. The overall eco-environmental quality on the QTP was low, and increased at a rate of 9.39% over the past 25 years, presenting a distribution of decreasing from southeast to northwest. The unused land and forest decreased, but those of grassland, water body, built-up land, and cultivated land increased. The area change in land use on QTP was small from 1990 to 2015. It provides a statistical measurement of system structure and more information than the traditional methods to reveal the land use change. In this study, an eco-environmental quality assessment index system was established to characterize the QTP, and the information entropy and elasticity methods were introduced to quantify the impact of land use dynamic trajectory on the eco-environmental quality. Although land use activities on the plateau have increased gradually in past decades, its effects on eco-environmental quality and the underlying mechanisms of regional heterogeneity remain unclear. ![]() The primitive ecosystem and environment of the Qinghai-Tibet Plateau (QTP) occupies a special position in the world, but it is very fragile. Regional land use change affects eco-environmental quality by altering ecosystem structure and function.
