Vegetation cover change and its response to climate extremes in the Yellow River Basin.

Extreme climate events have increased in frequency and severity under the background of climate change, with vegetation growth exhibiting a sensitive response to them. By assimilating GIMMS NDVI and MODIS NDVI using the Residual Network, we obtained a long time series and high resolution NDVI dataset of the Yellow River Basin (YRB). The dataset was utilized for examining the spatiotemporal variability of NDVI and analyzing the response of vegetation cover to climate extremes with meteorological data.

[Soil quality and its evaluation].

Preservation and improvement of soil quality is the basic task for agricultural sustainable development. For this reason, the concept and the evaluation method of soil quality should be clearly understood. In this paper, the concept of soil quality and its advanced researches were reviewed.
