The spatial-temporal differentiation characteristics and driving mechanisms of ecosystem services are great significance for optimizing the pattern land spatial protection realizing regional sustainable development. Existing studies seldom consider segmental influence mechanism various influencing factors on different levels service value (ESV). Therefore, this paper analyzes temporal evolution...
The transition of land use function and its effects on ecosystem services is a key issue in eco-environmental protection the basis territorial space governance optimization. Previous studies have typically selected types to evaluate service value (ESV) overlooked comprehensive characteristics mutual feedback relationship between human social systems ecosystem. Taking Three Gorges Reservoir Area...
The southern hilly mountains are rich in natural resources and one of the important ecological security barrier zones China. However, disturbance ecosystem caused by human activities has led to a differentiated character spatial services. Such spatially characteristics have not been well studied, thus bound limit our ability manage ecosystems sustainably. Taking Ruijin City, typical mountainous...
Accurate assessment and response analysis of land use cover change (LUCC), ecosystem service values (ESV), are critical to regional ecological security economic development. There is a lack detailed reports on the impact LUCC temporal spatial evolution ESV in Yinchuan City, which inconsistent with pilot urban design policy. This paper, using data City from 1980 2018, calculated ESV, analyzed pa...
Based on the equivalent factor table of terrestrial ESV in China 2010, this paper proposes a regionalized and interannual correction method. Taking southern Guangzhou as study area, which is located geometric center Guangdong–Hong Kong–Macao Greater Bay Area (GHM GBA), evaluated ecosystem service value (ESEV) (ESV) their changes 2004, 2010 2016 carried out grid processing, trend analysis global...
Structural changes in land use caused by urban development are one of the most important threats to ecosystem services. An in-depth study impacts that different patterns have on service value (ESV) can provide guidance for sustainable planning and ecological conservation. In this research, we sought explore response mechanisms services under scenarios from perspective “production–living–ecologi...
With the rapid development of Chinese economy, many negative effects of land use transitions under the pressure of rapid urbanization on local ecological system and environment have occurred. This paper examines the dynamic patterns of land use in Tianjin Binhai New Area experienced rapid urbanization, using high-resolution Landsat TM (Thematic Mapper) data in 1985, 1995, 2005 and 2010, and soc...
Under a background of uncoordinated economic development and the ecological environment, quantifying effect brought by land resource changes, have become research key hotspots. To explore use change its impact on ecosystem service value (ESV), analysis method, evaluation model, flow direction model two-dimensional graph theory clustering method were used to analyze profit loss ESV in Qiqihar 20...
Reasonable quantitative assessment on urban ecosystem health is conducive to the sustainable development of economy and human society. This paper quantitatively evaluated impact land use change services by building a comprehensive evaluation system (vigor–organization–resilience–ecosystem services), then analyzed spatial-temporal pattern, evolution characteristics, driving factors in Shanghai–H...
The ecosystem service value (ESV) is a critical metric for assessing the construction and protection of environment. research into ESV pattern future development trend in Loess Plateau Northern Shaanxi important conservation water soil enhancement natural environment region. In this study, variations distribution patterns study area from 2000 to 2020 were analyzed, influence various social fact...
