The relationship and obstacles between sustainable development (SD) ecosystem services (ESs) are crucial factors for SD decision-making ecological conservation strategies. production-living-ecological (PLE) functional perspective provides a new research entry point to analyze the interrelationship of human society ESs. In view this, based on Sustainable Development Goals (SDGs), this study esta...
Urban ecosystem services provide a wide range of to sustain life, social relation, health, etc., and address most the challenges, including climate change environmental pollution. While it is recognized that urban substantially contributes human well-being in cities, there less attention consider value service planning policymaking. This study analyzed land use cover (LULC) dynamics city Dhaka ...
Catchments support the survival and development of humans in a region investigating mechanism land-use changes ecological responses catchments is great significance for improving watershed service functions. Taking Dongting Lake catchment as study area, this used spatial analysis, an ecosystem value (ESV)-equivalent factor method, grid other analysis methods to explore corresponding response fr...
in this paper, we report an investigation of changes in land use and ecosystem services on loess plateau in northern shaanxi province from 1978 to 2004. we used three landsat tm and/or etm data sets to estimate changes in the size of five land-cover/land-use categories, and we also used previously published value coefficients to estimate changes in the value of ecosystem services delivered by e...
The Tarim River Basin (TRB) is situated in the hinterland of northwest China, which an extremely arid and fragile ecological zone. In recent years, region’s civilization construction has been facing huge challenges that are exacerbated by climate change human activities. order to verify current status TRB, this paper explores spatial temporal variation ecosystem service value (ESV) impact mecha...
Being closely related to ecosystem services, land use changes can affect service functions by acting on patterns and its processes, thus having impact regional sustainable development. Taking the Western Sichuan Plateau as study area based data from 1990 2020, CA-Markov model was employed predict pattern under natural change scenarios, improved InVEST equivalent method were used evaluate servic...
The arid region of northwest China is an extremely fragile area natural ecology. With population growth and continuous expansion urban scale, the ecosystem in facing greater pressure. Scientific assessment prediction value services areas are necessary great significance for sustainable development regional ecological environments. In this paper, a parametric optimal geographic model used to ana...
The evaluation of the ecosystem service value (ESV) and its regionalization toward coordinating ecological protection socioeconomic development is great significance. In this study, we developed a classification method based on Random Forest algorithm feature optimization to identify grassland types. Then, proposed an approach quantitatively evaluate ESV in Ethiopia, which net primary productio...
The new urbanization (NU) will lead to changed land use types, affecting the ecological environment and ecosystem service value (ESV). NU is affected by because of resource scarcity when damaged. levels ESV were used evaluate degree development provided services (ES), respectively, analyze their coupling coordination relationships. This study shows that (1) Nanchang city increases annually, at ...
Basin ecosystems are vulnerable to natural resource depletion, ecological damage, and environmental pollution due their fragile environment. Assessing the value of basin ecosystem services (ES) can facilitate informed decision making by policy makers stakeholders in context competing use. The Konqi River China, an arid inland river basin, has suffered from degraded overexploitation soil water r...
