Over the past decades, climate change has accelerated deterioration of heritage sites and archaeological resources in Arctic subarctic landscapes. At same time, increased tourism growing numbers site visitors contribute to degradation manipulation sites. This situation created an urgent need for new, quick, non-invasive tools methodologies that can help cultural managers detect, monitor, mitiga...

Drought poses a serious threat to agricultural production and food security in the context of global climate change. Few studies have explored response mechanism lag time drought meteorological from perspective cultivated land types. This paper analyzes spatiotemporal evolution patterns hysteresis relationship droughts middle lower reaches Yangtze River China. Here, Moderate Resolution Imaging ...

Water-use efficiency (WUE) is a crucial physiological index in carbon–water interactions and defined as the ratio of vegetation productivity to water loss. The variation climatic variables drought have most significant effects on WUE evapotranspiration (ET). Nevertheless, how varies with climate factors processes Tianshan Mountains (TMS) still poorly understood. In present work, we analyzed spa...

Studying grassland vegetation growing seasons’ spatial patterns and their environmental controls are crucial to promoting ecological restoration, formulating effective disaster prevention reduction measures building a stable barrier. However, multi-grassland phenological factors different, this has not been well studied before. In paper, the spatiotemporal of start season (SOS) end (EOS) in wer...

Accuracy soil moisture estimation at a relevant spatiotemporal scale is scarce but beneficial for understanding ecohydrological processes and improving weather forecasting climate models, particularly in arid semi-arid regions like the Chinese Loess Plateau (CLP). This study proposed Criterion 2, new method to improve relative (RSM) by identification of normalized difference vegetation index (N...
