Abstract The rapid process of urbanization and industrialization has intensified the competition among various stakeholders for land resources, leading to increasingly fierce mutual conversion between production, living ecological land, thus causing fluctuations in regional environmental quality. This study focuses on upper reaches Yangtze River (URYR), use data were obtained by interpreting five remotely-sensed images taken 1980, 1990, 2000, 2010, 2020. Using methods such as transfer matrix, quality index, geographic detector etc., conducts quantitative analysis transformation, eco-environmental effects, influencing factors URYR. results show that from 1980 2020, transformation is manifested an increase a decrease production land. primary type space evolution overall eco-environment declined. high-value areas are mostly concentrated southwest east, while low-value aggregation formed central western parts. Natural environment serve base influence strong weak topographic relief, slope, net productivity (NPP), mean annual temperature, altitude, intensity, economic density, average precipitation, road network population density diversity. research findings presented this paper can valuable reference fields conservation territorial spatial planning.

Investigating large-scale spatial patterns of ecosystem services (ESs) and their underlying drivers can greatly contribute to policies-making regional sustainability development. With water yield (WY), soil conservation (SC), carbon sequestration (CS) as representative ESs, we aim quantify in the Yangtze River Economic Belt, China, identify driving factors, formulate sound environmental management strategies. Spatial geography socioeconomic data from 2000 2020 were mined a range research methods, including multiscale geographic weighted regression, self-organizing maps, linear discriminant analysis, employed for such purpose. Annual average WY, SC, CS 403 mm, 9897 t·km−1, 1071 g·CO2·m−2. The three ESs examined exhibit heterogeneity. WY exhibited significant variation along north–south gradient, while SC topographic gradient. In context high correlation factors among greater sensitivity natural (such precipitation), demonstrated height human activities addition vegetation cover. heterogeneity is pronounced main ESs. Three threshold equations established describe manner which different undergo transformations, possessed level credibility this study (coincidence > 80 %). This reveals variations socio-economic drivers. More specifically, quantitatively validated expression service drivers, establishing strong scientific foundation management.

Territorial space is a multi-functional complex. The coordinated production-living-ecological (PLES) effectively coordinates the man-land relationship, promotes regional sustainable development, and maximizes territorial space. How to build high-quality national spatial layout support system for development has become hot topic of concern in all sectors society. However, few studies have explored coupling coordination considering various functions land use type its influencing factors PLES at county scale China. To address gap, based on connotation theory, this study established classification evaluation analyzed spatio-temporal characteristics, degree, autocorrelation, China from 2000 2020. results are as follows: (1) production index living showed continuous increase tendency, while ecological decreased continuously during period. were concentrated east Hu Line, indexes mountainous areas significantly higher than those plain (2) gravity centers migrated west different degrees (3) From 2020, basically balanced category was main type, number seriously unbalanced categories accounted least. In dominant, Line moderately above. (4) During period, low-low relationship widely distributed western China, followed by high-high mainly situated North Plain, Yangtze River Delta, Pearl Jianghan Chengdu Northeast some provincial capital cities. (5) Regression that natural reason restricting PLES, socioeconomic could promote PLES. Landscape pattern also influenced but varied greatly. findings can provide scientific reference optimization promotion

The coupling coordination degree (CCD) of the production-living-ecological space (PLES) functional index is an indicator regional sustainable development potential. However, previous studies have failed to reveal driving mechanisms CCD PLES on a global scale. Therefore, this study employed model evaluate and spatial regression models measure heterogeneous drivers using multi-source data in 2000, 2010, 2020. results demonstrated that ecological spaces dominated (85%) globally, while living comprised smallest share (3%). was higher than production indices. Further analyses revealed topographic factors were main restricting for PLES; proportion decreased with increasing altitude slope, whereas showed opposite trend. values 2020 0.186, 0.189, 0.198, respectively, showing High generally observed areas dense population industry where human activity systems interact natural ecosystems. formation pattern from joint action socioeconomic factors, pronounced heterogeneity. Our findings can help optimize territorial utilization, improve utilization efficiency, realize goals.

The identification of land type multi-functionality is a basic tool for the organization, coordination, and configuration basin land, provides key criterion determining combination land-use functions status quo ecological environment in basin. However, feasible method system this purpose has not yet been established. Therefore, study, we construct production–living–ecological space (PLES) classification from comprehensive perspective environment. Based on remote sensing PLES statistical data 2000, 2005, 2010, 2015, 2020, analyze evolutionary characteristics function using transfer matrix center gravity methods. These are combined with eco-environmental quality index to reveal driving factors spatial differentiation geographic detector model. results indicate that overall Tarim River Basin presents downward trend, pattern high northwest low southeast. Over past 20 years, dropped by 0.852. structural evolution regional areas remarkable, all which expanded over study period (except land). production presented most obvious migration, total migration 10,601.76 m northeast. Eco-environmental effects found be mainly driven socio-economic factors, population density growth important. implementation some restoration projects played role slowing down degradation trend Basin; however, due increases development, exacerbated.

High-intensity human activities have caused dramatic transformations of land function in China’s coastal zone, putting enormous pressure on the region’s ecological environment. It is urgent to fully understand spatiotemporal evolution land-use zone promote sustainable development. Therefore, based CNLUCC data for 2000, 2010, and 2020, this study quantitatively explored production–living–ecological (PLEL) its eco-environmental response by using multiple analysis methods, gradient analysis, quality index. The results showed that over past 20 years, production (PL) continued decrease, whereas living (LL) blue (BEL) increased. In vertical direction, PL (EL) dominated northern southern respectively. horizontal with increasing distance from coastline, green (GEL) increased, it was opposite BEL. PLEL were high low frequency north south, From 2000 slightly degraded, conditions “excellent south poor north”. qualities each sub-coastal gradually improved coastline. main transformation types led improvement degradation other lands (OPL) BEL OPL, findings will guide planning, protection, science-based usage.

This paper takes Caohai National Nature Reserve (CNNR) China as research object on basis referring to previous results. Firstly, remote sensing data was employed examine spatio-temporal evolution process CNNR from three aspects: structure change, dynamic degree and space change. Then quality studied greenness, wetness, dryness heat. Based spatiotemporal changes types in 2000 2020, a comprehensive index, index (RSEI), constructed analyze environmental effects changes. The results indicate that went through two major periods: first, period decline cultivated land, second, sharp increase land. During study area showed an upward trend. However, during increased gradually stabilized. provides for coordinated economy area.
