“…The four ecosystem services provided by Wafangdian forestland have changed steadily in 14 years, while coastal wetland and cropland have changed dramatically. Most previous studies showed that forest ecosystem had great natural recovery and ecology resilience, while wetland and farmland ecosystem were more fragile and less resilient (Liu et al, 2018;Seidl et al, 2014). Evidently, there was a linear correlation between ecosystem services and ecosystem resilience (Li et al, 2017).…”

Developing effective methods to coordinate the trade-offs among ecosystem services (ES) is important for achieving inclusive growth and sustainable development, and has been the focus of scholars and ecosystem managers globally. Using remote sensing and geographic information system (GIS) data, our study examined Wafangdian County of Liaoning Province as a case study to reveal the spatiotemporal evolution of four ES (food supply [FS], net primary productivity [NPP], water yield [WY], and soil conservation [SC]) and changes among their interactions. Then, an ordered weighted averaging model was introduced to simulate the optimal scenario of ES allocation. Results showed that: 1) The spatial and temporal changes in ES were significant over 14 years. All ES presented an inverted U-shaped growth curve from 2000-2014. 2) Synergies were observed within provisioning services, and there were trade-offs between provisioning services and regulating services, as well as provisioning services and supporting services. 3) The optimal scenario for Wafangdian was scenario 5 (trade-off coefficient, 0.68). The allocation of FS, NPP, WY, and SC in scenario 5 were 0.187, 0.427, 0.131, and 0.063, respectively. Implementing each ES weight of optimal scenario in land use management contributed to achieving intercoordination of ES. We propose to coordinate land and sea management to restore natural habitats that were expanded into in the high ES area. It is our anticipation that this study could provide a scientific basis for optimizing the allocation of ES and improving land use structure of coastal zones in the future.

“…Wetlands in forests have particular potential to be highly valued in terms of their conservation and use. Wetlands, which include mangroves, forests, carr, pocosin, and floodplains [15] are of great conservation value due to their rich biodiversity and function as land and water transition zones, including mitigating climate change impacts [5,16], wetland ecosystems have irreplaceable and important functions in protecting water resources and both globally and locally, the water cycle relies on wetlands [17].…”

The aim of this study was to determine the characteristics of forest wetlands by developing factors for site suitability and applying these factors to 107 sites in South Korea. We developed a forest wetland assessment in a Geographic Information Systems (GIS) environment to assess site suitability. We considered 16 factors including slope, elevation, visibility, land ownership, distance to city, and so on. We conducted an expert survey with experts to analyze the relative importance by using the Analytic Hierarchy Process (AHP). We found that the order of importance of the 5 criteria applied in this study was: (1) Natural Ecology, (2) Land Use, (3) Natural Landscape, (4) Tourist Attraction, and (5) Accessibility. We then analyzed the spatial characteristics of each site based on the AHP result and divided the 107 forest wetlands into three categories by cluster analysis. Sites with high scores on the assessment were primarily the landscape ecology or land use criterion. Our differentiation of these forest wetland characteristics could help enable policymakers to develop sustainable management with the aim of balancing conservation with utilization in ecotourism destinations.

Global environmental issues, such as pollution, desertification and biodiversity loss, which are attracting people's attention to the environment on which human beings depend [11][12][13]. These problems have seriously damaged the ability of many ecosystems to provide important services ISPRS Int.…”

Hemeroby is an integrated indicator used to measure the impact and degree of all human interventions on ecological components or ecosystems. The constant exploitation of resources is a strong interference of human beings to the natural environment. With the depletion of non-renewable resources, some cities with resource exploitation as their main industry—“resource-based cities”—are facing great development pressure. In order to quantify the impact of human disturbance on the natural environment and provide some scientific support for policy makers of the resource-based city, we used remote sensing images and landscape pattern metrics, introduced the synthetic hemeroby index model and analyzed the relationship between human disturbance and landscape pattern during 1990–2017. The results showed that: (1) The hemeroby in Daqing continued to rise during 1990–2017, and the main factor was the continuous expansion of the construction land and the reclamation of farmland. (2) In the areas with different hemeroby, there were significant differences in landscape pattern. In the areas with high-level hemeroby, the heterogeneity of landscape pattern was low, the aggregation among patches was high, and the shape of patches was regular, whereas the landscape pattern in the areas with medium-level hemeroby was just opposite. Although the heterogeneity of landscape pattern and the aggregation among patches were high in the areas with low-level hemeroby, the complexity of landscape was low and the shape of patches was regular. (3) In the temporal dimension, the increase of hemeroby contributed to the complexity of patch shape, the decrease of the aggregation among patches, and the fragmentation of landscape pattern. In the spatial dimension, the response in landscape pattern to human disturbance was relatively insensitive in the areas with low-level hemeroby, and this response was basically same in the high-level hemeroby and the whole study areas.
