Ecosystem service value (ESV) is a crucial indicator for evaluating ecosystem health, and identifying its spatial driving factors will help to provide scientific decision support ecological protection restoration. This study took the Liuxi River Basin in China as research object used equivalent method estimate regional ESV. In process of using Geodetector model (GDM), area was spatially stratif...
A clear understanding of the spatiotemporal evolution and driving factors ecosystem service value (ESV) landscape ecological risk index (ERI) can effectively link human well-being security, which is essential for sustainable management. Based on multitemporal land use data (1990, 2000, 2010, 2018), ESV ERI in Ulan Buh Desert was evaluated. The forces were quantitatively evaluated by Geodetector...
The concept of Ecosystem Service Value (ESV) is indispensable when balancing the need for economic development and ecological protection, because it can clarify assets values provided by a region. study spatio-temporal variation ESV in ecologically fragile regions helpful attempting to restore regional function. Taking area Western Jilin as an example, this paper analyzes spatial distribution s...
The assessment of sustainability in cropping system is an important issue for natural resources management and environmental protection. Incorporating the geographical information system (GIS) and remote sensing (RS) technologies, an initial idea of the crop sustainability assessing system was thus proposed, based on ecosystem services value (ESV) assessing criterions. The system is basically c...
Saline–alkali land is an important resource with high development potential and ecological product ecosystem service value (ESV). It of great significance for rational protection saline–alkali resources to carry out research on the evaluation methods ESV scientifically quantify development. Taking typical in Yellow River Delta Huanghe Island China as example, this constructed index system from ...
Eco-compensation is an effective means of coordinating ecological protection and economic development, the assessment its standards core content in study eco-compensation projects. To improve operability standards, taking Nujiang Prefecture as area, we combine equivalent factor method water footprint to evaluate ecosystem-service-value (ESV) spillover use market comparison calculate opportunity...
Habitat quality and ecosystem service value (ESV) are important foundations for sustainable development. Baoding, as the strategic hinterland of Beijing–Tianjin–Hebei, is great significance to regional ecological conservation urban Based on land-use data from 2000 2020, scenarios natural development (ND), water protection (WP), forest rehabilitation (FR), cultivated land (CP) in 2030 were predi...
Massive growth is posing threat to the ecological security and sustainability of cities. Ecosystem service value (ESV) risk index (ERI) assessment can be conducted enhance urban ecosystem management through enhanced recognition these values risks in decision-making. This paper aimed measure spatiotemporal ESV ERI for Shizuishan City located central China, and, based on this, how zone space usin...
Assessing the influence of landscape pattern changes on ecosystem service value (ESV) is critical for developing land-use polies and increasing services. The data sources include remote-sensing image statistical yearbooks from 2000, 2010, 2020. This study employs patch-generating simulation model, index, ecological estimation to analyse in patterns ESV Fujian coastal areas over last 20 years. f...
this study aims to quantify the impacts of land use changes on ecosystem service value during large scale land development, and to provide key information for both economic development and policy makers for eco-environmental protection. the study area locates in manas river watershed which is a typical land development region in northwest china. landsat mss/tm/etm+ images in 1976, 1989, 1999 an...
