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.

Urbanization has significantly impacted ecological connectivity, making the optimization of networks (ENs) crucial. However, many existing strategies focus on overall network structure and overlook spatial concentration local processes flow (EPF), limiting effectiveness planning. This study proposes a novel EN framework based urban–rural gradient zoning to enhance connectivity from perspective EPF. The divides areas outside core urban zone (CUZ) into fringe (UFZ), interface (UIZ), natural rural (NRZ), applying tailored in each zone. These include increasing corridor redundancy, reducing resistance, expanding width alleviate EPF concentration. Using Jinan, mega-city China’s Yellow River Basin, as case study, this simulated changes over 20 years validated framework’s effectiveness. Optimization validation showed that land low-flow corridors 65% UIZ NRZ 5 km improved by 6.3%, addressing seven pinch points three barrier points. highlights importance optimizing ENs via support sustainable development protection policies.

The construction of ecological networks and the optimization spatial layouts are essential for maintaining regional security promoting sustainable development, especially in high-population-density urban agglomerations. This study employs Central Plains Urban Agglomeration (CPUA) as a case to establish an network through quantitative assessments land use/cover change (LUCC) ecosystem service value (ESV), utilizing morphological pattern analysis (MSPA) methods tools such Linkage Mapper further optimize layouts. findings reveal following: (1) use structure within CPUA experienced notable shifts. magnitude changes ranked follows: > cultivated grassland waterbody forest bare land. (2) southwestern mountainous hilly regions, designated high ESV areas, primarily rely on water conservation soil retention functions. In contrast, central western characterized by low ESVs, dominated land, significantly influenced urbanization agricultural activities. (3) An system was developed based region’s natural geographic features, incorporating 20 sources covering approximately 21,434.70 km2, 36 corridors with combined length around 2795.19 km. extends north–south direction parts CPUA.

Constructing a rational ecological network is crucial for balancing regional development with environmental protection. However, existing research typically emphasizes the analysis of overall patterns, lacking an in-depth exploration dynamic changes in key elements and interactions between different components. Using Yongding River floodplain as case study, this study applied morphological spatial pattern analysis, landscape connectivity metrics, biodiversity assessments to identify core source areas. Circuit theory was used delineate corridors analyze evolution across four years, while graph facilitated structural characteristics. Furthermore, areas restoration were identified within floodplain. We found that number patches area has remained relatively stable, though their total shown fluctuating decline, accounting approximately 10% Additionally, have decreased significantly from 1967 2021, marked reduction major corridors, leading increased resistance material energy flow corresponding decline stability. More importantly, current pinch points are primarily distributed bead-like along channel, barriers concentrated northern eastern floodplain, often at intersections dense road networks corridors. These critical fragmentation prioritized targeted protection efforts. Overall, advances our understanding distribution composition river corridor offers framework evaluating these through multidimensional optimization approach patches.

The ecological conservation of nature reserves has garnered considerable attention and is subject to stringent management in China. However, the majority these areas have a history underdeveloped economies require urgent improvements well-being local communities. Effectively coupling harmonizing dynamic relationship between ecosystem services socio-economic development emerged as crucial concern for reserves. Therefore, further exploration needed achieve spatio-temporal balance alignment supply demand ESs Utilizing multiple datasets, RULSE, bivariate autocorrelation methods, this study investigated evolution supply–demand ratio (ESDR) spatial matches soil (SCSs) Qinling Mountains (QMs) from 2000 2020. results indicated following: (1) Over years, SCSs exhibited consistently high level, with an upward trend observed 63.10% QMs, while generally low, decreasing 82.68% QMs. (2) remained favorable, positive ESDR reaching 82.19% From 2010, there was significant decline ESDR; however, substantial rebound across region 2010 (3) counties districts values ESDR. When examining cities, Weinan, Xi’an, Ankang demonstrated relatively consistent patterns higher over time. In 2000, on northern slope lower than that southern slope; situation subsequently underwent reversal. (4) distribution SCS predominantly characterized by matching regions exhibiting either High Supply–High Demand or Low Supply–Low years. This suggests dynamics been favorable recent matches. These findings can provide valuable insights similar aiming implement environmental protection sustainable development. future research endeavors, should strive expand upon exploring associated other diverse reserves, considering their unique geographical characteristics, order promote more rational strategies.
