On basis minimum cumulative resistance (MCR) model and cellular automaton (CA)-Markov model, we constructed new technical method delineating boundaries, exploring temporal spatial distribution characteristic land use in Wuhan from 2010 2020 through nighttime remote sensing images, simulating boundaries 2025 2035. The results show that: (1) scales City’s built-up areas 2010, 2015, were 500 km2, 566.13 885.11 respectively, trends expansion run east southeast, (2) on MCR boundary scale City 2025, 2030, 2035 perspective actual supply will be 903.52 937.48 1021.44 based CA-Markov ideal demand 912.75 946.40 1041.91 respectively. By combining two methods, determined 901.62 944.39 1015.36 km2 as 2035, According principle supply–demand balance, delineated by integration which line with trend growing cities, could optimize pattern; solve contradiction between development, farmland protection, ecological protection; methodological decision-making planning practice.

Delineating urban growth boundaries (UGBs) has been proved as an effective approach to constrain encroachment and achieve sustainable development. However, so far, many studies have not fully taken account of the ecosystem integrity in simulating well corresponding UGBs delineation. To bridge this research gap, paper proposes ESP-FLUS model predict future land use pattern with a comprehensive consideration ecological protection. In paper, on one hand, security (ESP) is integrated from four aspects (i.e., hydrology, geology, biodiversity, recreation) classified into three levels basic ESP, intermediate optimal ESP). On other drawing historical records, random forest coupled Gini importance are applied identify driving factors shaping variation. Taking ESP spatial constraint allied identified FLUS model, predicts 2035 multi-scenario manner.

Rapid urbanization and human activities make the contradiction between ecological environment more obvious, maintaining balance achieving harmonious development living has also become main goal of sustainable development. The urban agglomeration on northern slope Tianshan Mountains (UANSTM) is a typical arid inland emerging agglomeration, relationship here very sensitive. To reveal spatiotemporal changes in quality UANSTM from 2000 to 2020, this study used Google Earth Engine (GEE) platform, calculating remote sensing index (RSEI) based MODIS data products, addition an space atlas Land-Use Land-Cover Change (LUCC) sets. At same time, geographical detector model (GDM) been exploring influencing factor RSEI. result shows that 1) mean value RESI area continued rise first 15 decreased slightly last 5 a. 2) In past 20 a, improvement obvious (IO) gradually expanded, proportion increased. sum areas deterioration (DO) slight (DS) far smaller than (IS) (IO), which indicates UANSTMN tends improve. 3) distribution land (EL) > semi-ecological (SEL) weak (WEL). EL decreasing, while SEL WEL increasing. 4) RSEI greenness, interaction heat, dryness, greenness had effect better with higher wet, lower dryness or heat.

The Henan section of the middle and lower Yellow River (HMLYR) is a crucial economic zone ecological barrier in Central Plains. Rapid urbanization these areas has greatly exacerbated land use change (LUC), which now seriously threatening ecosystem. However, existing research lacks any spatio-temporal analyses method LUC impact on ecosystem service value (ESV), not conducive to precise regulation sustainable development resources. We attempted make up for this shortcoming by superimposing ESV hot spots map onto Tupu constructing an evaluation model show effect from spatial dimension. Our results showed that (1) cultivated was main type HMLYR. transformation construction had widest range largest area. (2) Between 2000 2018, decreased 9.774 billion CNY distribution consistent with topography. Forestland major type, while services types were mainly support (3) Construction changes greatest ESV. Conversion into water bodies forestland formed spot around River, transition other grassland, forest land, cold urban areas. (4) sensitivity index all less than 1, indicating coefficient (VC) little influence Decision-makers should recognize important take measures restructure use, especially develop lands.

Land use and land cover (LULC) contribute to both carbon storage emissions. Therefore, regulating the LULC is an important means of achieving neutrality under global environmental change. Here, West Liaohe River Basin, a semiarid watershed, was taken as case study. Based on assessment emissions induced by from 2000–2020, we set up three different coupled shared socioeconomic pathway (SSP) representative concentration (RCP) scenarios (SSP119, SSP245, SSP585), 2030–2060, optimize LULC. Then, patterns each scenario were simulated using patch-generating simulation (PLUS) model, corresponding changes in compared analyzed. It found that, since 2000, with expansion forest, cropland, construction land, well degradation grassland, have significantly increased, but increase lower than that The simulations revealed when LULC, mainly including protection ecological such forest grassland western southern edges basin, control management cropland northeast central parts there will be significant reduction 2030–2060. This indicates zone-based measures rational regulation can achievement study area. Supported results this study, direct decision-making basis for policy promote regional sustainable development undertaken basin. also provides reference low-carbon other regions.
