The prolonged and rapid urbanization has intensified land use conflicts, consequently escalating ecological risks. However, the current deficiency in acknowledging adverse impacts of these conflicts hampers effective identification governance. Taking urban agglomeration middle reaches Yangtze River (UAMRYR) as an example, we analyzed regional terms scope, intensity, spatial–temporal patterns based on "risk-effect" conflict framework center gravity-standard deviation ellipse method. Subsequently, elucidated dynamic response 12 natural-social factors to changes intensity using a random forest model. results showed significant 2.9 % decrease proportion areas during latter decade (2010–2020) compared first (2000–2010), there was noticeable shift gravity towards northwest. Over past 20 years, predominant UAMRYR been characterized mild moderate. Specifically, moderate area accounted for 16.02 8.51 region's total from 2000 2010. This decreased 15.84 7.62 2010 2020, respectively. Variations were mainly influenced by climate (annual precipitation, average annual temperature), topography (elevation), economic development (GDP density), displaying pronounced nonlinear characteristics. Accordingly, investigation driving mechanism governance should fully consider influencing factors. Additionally, this study provides methodological guidance identifying rapidly urbanizing areas, serving foundation decision-making territorial spatial

In recent years, rapid economic development, increasing human activities, and global climate change have led to escalating demands for land across production, residential, ecological domains. This surge has heightened use conflicts, significantly impacting sustainable utilization regional development. Drawing upon the “Production–Ecological–Living Space” (PELS) theory, this study employs a Patch-generating Land Use Simulation (PLUS) model project PELS of Harbin–Changchun Urban Agglomeration (HCUA) under four scenarios 2030. Introducing concepts absolute relative conflicts in use, utilizes spatial comprehensive conflict index (SCCI) assess progression from 2000 2020 various 2030, while remote sensing (RSEI) is utilized evaluate evolution 2020. The results indicate following: (1) From different HCUA dominated by forest space (E1) agricultural production (P1), with no substantial alterations overall distribution PELS. (2) Absolute between are mainly concentrated plains western regions, characterized arising encroachment living on space; however, declined annually, accompanied notable enhancement quality.

Synergizing economic growth and carbon emission reduction in China: A path to coupling the MFLP and PLUS models for optimizing the territorial spatial functional pattern

The Science of The Total Environment, Год журнала: 2024, Номер 929, С. 171926 - 171926

Carbon emissions caused by economic growth are the main cause of global warming, but controlling to reduce carbon does not meet China's conditions. Therefore, how synergize and emission reduction is only a sustainable development issue for China, also significant mitigating warming. The territorial spatial functional pattern (TSFP) carrier coordinating emissions, establish TSFP remains unresolved. We propose decision framework optimizing coupled with multi-objective fuzzy linear programming patch-generating land use simulation model, provide new path in China. To confirm reliability, we took Qionglai City as demonstration. results found spatiotemporal coupling between synergistic effect (q ≥ 0.8220), which resolves theoretical uncertainty about synergizing through TSFP. urban space 2025 2030 obtained was 6497.57 hm2 6628.72 respectively, distributed central eastern regions; rural 60,132.92 56,084.97 hm2, concentrated east, few located west; ecological 71,072.52 74,998.31 mainly western southeastern areas. Compared 2020, intensity that realized synergy (decoupling index 0.25 0.21, respectively) reduced 0.7 4.7 tons/million yuan, respectively. Further confirming an effective way reduction, can policy implications China even similar developing countries.

Territorial spatial conflicts (TSCs) refer to a contradiction of utilization resulting from the inconsistency needs and objectives different subjects interest for resources in planning, utilization, management. This research aimed unveil TSCs, construction land expansion (CLE), their relationship Guizhou Province 1980 2020, both temporally spatially. paper established indicators assess CLE, including velocity, intensity, pattern analyze characteristics Province. At same time, territorial conflict indicator (SCII) was constructed study TSCs Province, its evolution explored through cold hotspot analysis. On this basis, it investigated linkage between CLE ordinary least squares (OLS) regression model geographically weighted (GWR) model. Furthermore, also an economic elasticity coefficient population collaborative GDP along with volume. The revealed that while velocity intensity have escalated over displayed considerable geographical variation across various locations. Simultaneously, intensified, demonstrating slight positive correlation expansion. temporal response provided reference optimization regional space. It is highly valuable significant fostering efficient resources, adjusting social transformations, improving scientific rigor planning.

The low-carbon utilization (LCU) of territorial space represents a critical strategy for addressing climate change and promoting sustainable development, yet current assessments in this domain remain insufficient. This study develops an integrated assessment framework utilizing kernel density estimation, optimal parameter-based geographical detector, the Tobit regression model to analyze spatiotemporal evolution, typology, driving factors LCU Yangtze River Economic Belt. findings reveal that index region increased from 0.548 2005 0.569 2020, despite significant regional disparities. Cities are classified into eight distinct types LCU, with over 80% demonstrating poor performance at least one functional space, particularly urban where number cities below average is highest. analysis demonstrates spaces influenced by integration natural conditions, socio-economic factors, landscape patterns. In light these findings, systematically proposes policy recommendations enhance space. research contributes establishment scientific evaluation providing empirical evidence improve spatial governance policies support development.

Cultivated land plays a crucial role as the basis of grain production, and it is essential to effectively manage unregulated expansion non-grain production (NGP) on cultivated in order safeguard food security. The study NGP has garnered significant attention from scholars, but prediction trends relatively uncommon. Therefore, we focused Jiangsu Province, region China, area. We extracted data for (NGPCL) 2000, 2005, 2010, 2015, 2019, calculated ratio (NGPR) each county unit province. On this basis, Kernel Density Estimation (KDE) spatial autocorrelation analysis tools were utilized uncover spatio-temporal evolution Province. Finally, Patch-Generating Land Use Simulation (PLUS) model was predict trend Province 2038 under three development scenarios natural (NDS), protection (CPS), security (FSS). After analyzing results, came following conclusions:(1) During period 2000–2019, NGPCL area NGPR exhibited general decreasing trend. (2) level displayed distribution pattern being “higher south central lower north”. (3) results multi-scenario simulation show that NDS, (GPCL) decreases significantly; CPS, decrease GPCL smaller than NDS. Under FSS, decreases, while increases.

Land Degradation and Development, Год журнала: 2024, Номер unknown

Опубликована: Окт. 1, 2024

ABSTRACT Conflicts between different types of land use, driven by rapid urbanization, are altering ecosystem services supply–demand balances (ESDB), and the reduction ESDB will threaten regional sustainable development human welfare. However, there few studies on interrelationships their drivers use conflicts (LUCs) from a coupling perspective, especially in main functional areas. Therefore, this study focused Southwest China. Firstly, coordination degree model was employed to measure ESDB‐LUCs relationship analyze its dynamic changes 1990 2020. Then, RDA method used explore driving factors areas (i.e., urban area (UDA), agricultural (APA), ecological protection (EPA)). The results show that LUCs index displayed downward trend SW during 1990–2020, with decreasing distribution pattern northeast southwest. exhibited then upward trend, an increasing mode There spatial dependence ESDB. type dominated moderate coordination, showing UDA > APA EPA. Among these, proportion cropland were influencing (explanation rate 80%), positive negative effects, respectively. forestland EPA 70%), mitigating conflict land, forest is essential achieve balance SW.
