Under the background of rapid urbanization, strengthening research on response and dynamic mechanism ecosystem services to land use is conducive optimization space ecological restoration governance in megacities. Using Hefei City as a case study, we examined specific analyzed how water yield, habitat quality, carbon storage, soil conservation changed over time from 2000 2020. We utilized spatial information technology InVEST model assess these changes. Additionally, developed comprehensive service index (CES) used Geodetector regression models investigate responded use. In addition, Patch-generating Land Use Simulation Model (PLUS) simulate distribution 2030. This was performed under four different scenarios: natural development (ND), urban (UD), cultivated protection (CP), (EP). Furthermore, assessed effects land-use changes functions by integrating PLUS results with InVEST. The findings indicate following: (1) between 2020, farmland consistently remained dominant type while construction experienced significant growth. Land-use conversion prevalent during this period, each indicator exhibited noticeable geographic variation; (2) past 20 years, clear clustering patterns. types showed quantitative relationships CES.

A marine nature reserve is an area designated by law for the special protection and management of sea areas, coasts, estuarine wetlands, islands, other areas needing protection, including objects exceptional conservation value. The purpose these reserves to protect natural environment resources sea. construction China’s protected can be traced back establishing Snake Island Nature Reserve in 1963. Over past six decades, China has established a network specially (including parks), which have played pivotal role safeguarding biodiversity, promoting integration land sea, defending country’s maritime rights interests. Nevertheless, challenge solve. It imperative further advance development enhancing spatial planning streamlining system, delineating interests associated with using areas.

Urbanization and economic growth have substantially modified the land utilization structure, affecting ecosystem services their spatial distribution. As a crucial component of Beijing’s urban framework, city’s green belts, located at periphery its core metropolitan area, play vital role in supplying services. They also represent focal point for use transformation conflicts, making them an important study area. This research utilizes data from 2000, 2005, 2010, 2015, 2020 as primary dataset. It adopts standard equivalent factor integrates it with Patch-Generaling Land Use Simulation (PLUS) model to belts 2035 under three scenarios: natural development scenario (NDS), ecological protection (EPS) cultivated (CPS). The aims analyze project temporal evolution service values (ESVs) different scenarios Beijing. results indicate that (1) is dominated by cropland construction land. Construction has expanded significantly since increasing 500.78 km2, while decreased 488.47 km2. Woodland, grassland, water seen reduction. Overall, there trend woodland being converted into cropland, subsequently transitioning (2) In NDS, increases 91.76 decrease. EDS, decelerates 22.09 reduction decelerates, conversion limited. Grassland remain largely unchanged, experiences slight increase. CPS, notably reduced, 11.97 slightly, grassland decreasing slightly. (3) ESV ranking across follows: EPS 1830.72 mln yuan > CPS 1816.23 NDS 1723.28 yuan. Hydrological regulation climate are dominant all scenarios. attains greatest gains. contributes understanding effects changes on ESV, offering valuable empirical evidence sustainable decision-making swiftly urbanizing areas.

ABSTRACT The Semporna Priority Conservation Area (PCA), located on the southeast coast of Sabah, Malaysia, spans 7680 km 2 within Sulawesi Sea and is part Coral Triangle, known for its rich marine biodiversity. Despite ecological significance, area faces multiple anthropogenic threats. study aimed to (1) evaluate reef health by assessing live coral cover, indicator fish invertebrate density in six locations Semporna; (2) examine survey team's threat rankings with vulnerability factors perceived experts; (3) compare scores 10 identified Underwater surveys were conducted using Reef Check methodology, supplemented situ observations from SCUBA divers boat attendants May–June 2017. Marine biologists or scientists familiar assessed based scales, frequency, functional impact, resistance, recovery time certainty towards different main threats include bombing, debris, commercial fishing artisanal fishing. Results indicate degradation, particularly destructive practices, highlight differences between local made field team expert assessments gathered through interview surveys. Tourism activities significant Centre Southwest Northeast regions, necessitating site‐based management. This integrated approach provides a comprehensive understanding PCA underscores importance combining empirical data insights guide management prioritisation develop effective conservation strategies, such as establishing new protected areas.
