The improvement of habitat quality is great significance to biodiversity conservation. Irrational development activities lead the degradation and loss biodiversity, especially in arid inland areas where ecological environment fragile. In this study, InVEST model used evaluate degree Ebinur Lake Basin from 1990 2020, while PLUS predict land use change under various scenarios. Combined with results zoning planning, spatial distribution inertia (ID) protection (EP) scenarios 2030 were compared analyzed, optimal scenario was selected. following four conclusions are drawn: (1) From cultivated land, grassland, construction significantly increased, forest water bodies, unused decreased. (2) watershed showed an increasing trend followed by a decreasing trend. area proportion high has always exceeded 50 % total level quality. (3) Furthermore, combined human footprint index (HFI), planning for basin conducted. three zones divided into key protected areas, restoration moderate zones, proportions 53.69 %, 29.37 16.93 respectively. (4) By comparing ID EP 2030, we found that increased 2730.06 km2 scenario, which improved overall quality, more conducive security basin. study may benefit analysis temporal variation characteristics provide reference region.

Carbon balance dynamic evolution and simulation coupling economic development and ecological protection: a case study of Jiangxi Province at county scale from 2000–2030

International Journal of Digital Earth, Journal Year: 2025, Volume and Issue: 18(1)

Published: Jan. 3, 2025

In addressing global climate change and promoting economic growth, achieving a comprehensive carbon balance at the county level is vital for sustainable development. However, most studies focus on between emissions sequestration (CESB), neglecting intricate ecological (EECB) this scale. This study introduces an analytical framework that couples development with protection by using coupling coordination degree analysis, zoning, Markov-PLUS model. Taking Jiangxi Province as case study, we evaluate spatio-temporal dynamics of from 2000–2020 predict future trends 2030 under four potential scenarios. Results reveal significant regional variations in CESB over two decades, which primarily exhibit net emission. Meanwhile, continuous decline EECB highlights need balanced By 2030, land use's capacity expected to increase different scenarios, leading 'middle-high, sides-low' spatial pattern CESB. These findings are crucial policymakers devising strategies
