The Songliao Plain is the largest maize (Zea mays L.) cropland area in China and, thus, most influenced by water stress. To mitigate adverse impact of stress on yield and quality, various agricultural irrigation strategies have been implemented. Based land surface temperature an enhanced vegetation index, this study constructed dryness index (TVDI) combined Hurst Sen trend to analyze spatiotemp...

The temperature vegetation dryness index (TVDI) is widely used for the monitoring of global or regional drought because its strong drought-monitoring capabilities and ease implementation. However, temporal errors in land surface (LST) normalized difference (NDVI) can affect warm cold edges, thus determining quality TVDI, especially regions affected by climate change, such as Shandong Province. ...

Surface soil water content (SWC) is a major determinant of crop production, and accurately retrieving SWC plays crucial role in effective management. Unmanned aerial systems (UAS) can acquire images with high temporal spatial resolutions for monitoring at the field scale. The objective this study was to develop an algorithm retrieve by integrating texture into vegetation index derived from UAS ...

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 ...
