    Construction land transition in Qinghai-Tibet Plateau and its eco-environmental effects during 2000-2020 by ZHANG Zining, LUO Junqiang, ZHANG Peilei, RONG Han, LIU Haiyang, AN Shuang, CHANG Genying

    Published 2025-01-01
    “…Early expansion mainly occupied unused land, whereas later expansion predominantly encroached on ecological land such as cropland, forest, and grassland. Regional differences in land-use transitions were evident: the Northern Tibet Plateau and Qaidam Basin showed higher proportions of transitions to water bodies, water conservancy land, and unused land, while the expansion mainly occupied grasslands and unused land; in other regions, construction land predominantly shifted between cropland and grassland. (3) The <i>IRSEI</i> values of construction land in the regions of Qinghai-Tibet Plateau were ranked as follows: Sichuan-Tibet alpine canyon region &gt; Qilian Mountains region &gt; Southern Tibet valley region &gt; Qinghai Plateau &gt; Qaidam Basin &gt; Northern Tibet Plateau. (4) Overall, construction land transition demonstrated negative ecological effects. …”
