Ecological management zoning is crucial for maintaining regional ecological security and realizing differentiated urban governance. However, the existing methods are overly focused on functional attributes fail to adequately consider impacts of human activities, resulting in an insufficiently rational allocation resources. Taking Guizhou Province as example, using multi-source data spatial analysis tools, this study proposed framework based coupling blue-green infrastructure (BGI) network gray (GI) network. The results indicated that (1) BGI area included 179 sources, with a total 54,228.80 km2, 232 corridors. (2) There were 53 sources GI network, totaling 709.19 corridors first, second, third levels 11,469.31 km, 6703.54 5341.30 respectively. (3) 606 barrier points identified, mainly distributed central part area, disturbance zone was 1132.50 which had largest distribution Qiandongnan, followed by Qiannan. (4) At county scale, five zones identified four indicators, namely, source ratio corridor density ratio, point. Then, we targeted optimizations restorations each zone. This organically linked anthropogenic identify zones, will provide new perspectives synergies between protection economic development.

The Huaihe River Eco-Economic Belt (HREEB) is a pivotal region in China’s national strategic planning. Land use this crucial to improving ecological quality and ensuring food security. Using the PLUS model Geodetector, we evaluated contribution interaction of 10 drivers production–living–ecological land (PLEL) performed multi-scenario simulations PLEL. results show that following: (1) Ecological mainly affected by elevation (contribution value > 0.16 for forest, grassland, water). Production influenced topographic relief, elevation, GDP per capita 0.13). Living driven capita, population density Interaction analysis shows nonlinear or two-factor enhancement among factors. (2) HREEB has relatively stable spatial pattern. Simulation indicate will not exceed 12% change next 50 years. (3) By 2075, under various scenarios predict significant changes area. Compared with natural development scenario, production increased 14.8% farmland protection living 14.3% urban scenario. This research vital managing developing PLEL resources within HREEB.

Land use change significantly influences landscape pattern adjustments, thereby altering ecosystem functions and service flows, ultimately impacting value (ESV). However, previous studies have often examined the impacts of land patterns on services from a one-dimensional perspective, overlooking complex interactions among these factors. This study proposes “process–structure–value” response framework applies it to case western Sichuan urban agglomeration. Its aim is identify spatial temporal characteristics evolution. Additionally, quantitatively evaluates synergistic effects changes ESV evolution 2000 2020 using correlation analysis. The results show that, over past 20 years, area experienced significant expansion construction by 184,729.41 hm2, leading dispersion fragmentation arable land, grassland, waters, resulting in an overall trend diversification patterns. increased CNY 2.619 billion, primarily due associated with forest waters. found that processes structures enhanced ESV. transition waters notably improved Meanwhile, diversity patch connectivity further function. Furthermore, ecological environment remained vulnerable despite Overall, highlight between processes, patterns, ESV, emphasizing necessity integrating future research comprehensively assess responses providing more comprehensive reference for planning policy development.

Examining the spatiotemporal changes of territorial space is crucial for addressing conflict between economic-social development and natural environment achieving optimal utilization. However, there a research gap regarding spatial characteristics optimization in mountain–flatland area. To address this gap, paper focuses on urban agglomeration Central Yunnan (UACY) as representative mountain-flatland A classification model was established. Based evaluation production– living– ecological functions, economic models were introduced to measure balance degree, further researched evolution coupling coordination by analysis from 2010 2020. The findings indicate following: (1) study area exhibited distinct differentiation, with "western mountainous counties (MCs)/semi-mountainous semi-flatland (SMSFCs), central flatland (FCs), eastern SMSFCs". production function (PF) primarily formed cluster central-northeastern areas FCs SMSFCs, living (LF) highly clustered FCs, remained stable, (EF) significantly northwestern regions MCs enhanced northeast. (2) imbalance degree followed order LF > PF EF, showing decreasing trend driven intra-group imbalances within MCs. coordinate mainly concentrated dysfunctional largely located improved, especially southeastern SMSFCs. (3) fell into 18 functional areas, optimized 13 recommendations differentiated control paths achieve an PLEFs.
