Forested catchments are generally assumed to provide higher quality water. However, this hypothesis must be validated in various contexts as interactions between multiple land use and land cover (LULC) types, ecological variables and water quality variables render this relationship highly complex. This paper applies a straightforward multivariate approach on a typical large monitoring dataset o...
Forests in Washington State generate substantial economic revenue from commercial timber harvesting on private lands. To investigate the rates, causes, and spatial and temporal patterns of forest harvest on private tracts throughout the Cascade Mountains, we relied on a new generation of annual land-use/land-cover (LULC) products created from the application of the Continuous Change Detection a...
Rapid urbanization, land scarcity, and accompanying ecological deterioration in China have received growing attention. In this paper, two fast-growing metropolitan regions, Greater Shanghai and Greater Hangzhou, were selected as case studies to quantify the impact of land use/land cover (LULC) change on regional ecosystem services value (ESV) at the landscape scale since the late 1970s. The res...
This study analyzes land use dynamics, spatiotemporal patterns of ecosystem service value (ESV), and the forces driving growth in the Hangzhou metropolitan area (HMA) in China. An integrated approach utilizing a Geographic Information System (GIS) and Remote Sensing (RS) was used to extract information on land use/land cover (LULC) change over the period of 1978–2008 from time-series Landsat MS...

Owing to limited land resources and unique ecosystems, islands face more serious ecological risks under the interference of climate change human activities. In this study, selecting Zhoushan Island as study area, a landscape risk index model was constructed based on LULC (land use/land cover) data for from 2000 2020 were analyzed. The results showed that: (1) From 2020, proportion forest grassl...
Unprecedented rates of changes in land use/cover (LULC) on the local and regional scales lead to alterations of global biogeochemical cycles, and loss of productive ecosystems and biodiversity. Driving forces behind LULC changes mainly include rapid growth rates of population and consumption, lack of valuation of ecological services, poverty, ignorance of biophysical limitations, and use of eco...
