With the advancement of remote sensing technology, acquisition ultra-high-resolution imagery has become a reality, opening up new possibilities for detailed research and applications Earth’s surface. These images, with spatial resolutions at meter or sub-meter level pixel counts exceeding 4 million, contain rich geometric attribute details surface objects. Their use significantly improves accuracy feature analysis. However, this also increases computational resource demands deep...
Global warming significantly affects forest ecosystems in the Northern Hemisphere’s mid-to-high latitudes, altering tree growth, productivity, and spatial distribution. Additionally, temporal heterogeneity exists responses of different species to climate change. This research focuses on two key China’s Greater Khingan Range: Larix gmelinii (Rupr.) Kuzen. (Pinaceae) Quercus mongolica Fisch. ex Ledeb. (Fagaceae). We utilized a Maxent model optimized by kuenm R package predict species’...
Under the background of increasing global climate change, understanding impact variables on forest ecosystems has become an important topic in ecology and climatology. To explore connection between tree-ring density climatic variables, Pinus sylvestris var. mongholica (Ps) trees growing at northwestern foot Greater Khingan Mountains (GKM) were selected as research subjects. Correlations their index factors analyzed using basic theory methods dendrochronology. The impacts either variable...
We developed a tree ring width chronology from 1797 to 2020 (224 years) for the northwestern foothills of Greater Khingan Mountains (GKMs) in northeastern China using 51 sample cores 24 Pinus sylvestris var. mongolica (PSM). Pearson’s correlation analysis was used analyze relationship between and regional climate factors. The standardized positively associated with minimum temperature (Tmin) previous May (r = 0.721, p < 0.01), indicating that this parameter main climatic factor limiting...
To study the radial growth of Mongolian pine (Pinus sylvestris var. mongholica, MP) trees in response to climatic factors against global warming background northeast part Greater Khingan Mountains (GKM), 101 tree cores were collected at contrasting altitudes (1100 and 650 m) Mordoga area, a tree-ring width chronology MP was established for that region both altitudes, relation between ring trends different time scales investigated. The results revealed four major findings. (1) low-altitude...
Soil erosion (SE) threatens food security and the environment, predictive models are essential for guiding prevention efforts. This study couples PLUS-InVEST model with CMIP6 climate dataset to examine land use SE changes in Xijiang River Basin (XRB) from 2000 2020 predict scenarios 2030. Using Geodetector, influence of six driving factors on was analyzed. Key findings include:(1) Human activities XRB have intensified, development growing 2.09 times faster recent years. Rapid urban expansion...
