“…For the surface water ecosystem, the effects of drought were analyzed for rivers, wetlands, and slope ecosystems. Because the long-term vegetation index is a powerful tool for analyzing changes in ecological and climatic processes [21,22], remote sensing data of GIMMS NDVI were used to determine the effects on slope ecosystems.…”

This study produced a drought map for the Fenhe River basin covering the period from 150 BC to 2012 using regional historical drought records. Based on meteorological and hydrological features, the characteristics and causes of water scarcity in the Fenhe River basin were examined, along with their impact on the national economy and ecological environment. The effects of water scarcity in the basin on the national economy were determined from agricultural, industrial, and domestic perspectives. The impact on aquatic ecosystems was ascertained through an evolution trend analysis of surface water systems, including rivers, wetlands, and slope ecosystems, and subterranean water systems, including groundwater and karst springs. As a result of these analyses, strategies are presented for coping with water scarcity in this basin, including engineering countermeasures, such as the construction of a water network in Shanxi, and the non-engineering approach of groundwater resource preservation. These comprehensive coping strategies are proposed with the aim of assisting the prevention and control of water scarcity in the arid and semi-arid areas of China.

“…LTDR AVH13C1 products are supported by the LTDR project that was funded as part of the National Aeronautics and Space Administration (NASA) Earth Science Research, Education, and Application Solution Network. This was designed to derive consistent and longtime datasets from the Advanced Very High Resolution Radiometer (AVHRR) series of satellites (NOAA 7, 9, 11, 14, and 16) [32] and MODIS apparatuses for application in global climate warming research studies [33]. The LTDR AVH13C1 products consisted of a series of daily NDVI data, which was produced with a spatial pixel resolution of 0.05° for the period 1981-1999.…”

“…Both datasets have considered the effects of atmospheric and geometric calibrations, particularly for those deviations that are generated by the satellite shift to ensure the quality of the data [33,37]. MOD13C2 monthly datasets were generated by employing the maximum value composite (MVC) approach to further reduce the influence of clouds, atmospheric conditions, and the solar zenith angle.…”

Permafrost is extremely sensitive to climate change. The degradation of permafrost has strong and profound effects on vegetation. The permafrost zone of northeastern China is the second largest region of permafrost in China and lies on the south edge of the Eurasian cryolithozone. This study analyzed the spatiotemporal variations of the growing-season Normalization Difference Vegetation Index (NDVI) in the permafrost zone of northeastern China and analyzed the correlation between NDVI and ground surface temperatures (GST) during the years 1981-2014. Mean growing-season NDVI (MGS-NDVI) experienced a marked increase of 0.003 year −1 across the entire permafrost zone. The spatial dynamics of vegetation cover had a high degree of heterogeneity on a per pixel scale. The MGS-NDVI value increased significantly (5% significance level) in 80.57%, and this increase was mostly distributed in permafrost zone except for the western steppe region. Only 7.72% experienced a significant decrease in NDVI, mainly in the cultivated and steppe portions. In addition, MGS-NDVI increased significantly with increasing growing-season mean ground surface temperature (GS-MGST). Our results suggest that a warming of GS-MGST (permafrost degradation) in the permafrost region of northeastern China played a positive role in increasing plant growth and activities. Although increasing ground surface temperature resulted in increased vegetation cover and growth in the short time of permafrost degradation, from the long term point of view, permafrost degradation or disappearance may weaken or even hinder vegetation activities.

“…In the semi-arid forests of inner Asia, tree growth has declined since 1994 due to a temperature-induced reduction in effective moisture (Liu et al 2013). However, an increase in vegetation cover occurred between 1991 and 2000 on the Loess Plateau, especially in hilly regions (belonging to the semi-arid region), mainly as a result of ecological restoration (Sun et al 2015). The transition zones between forest and non-forest biomes, therefore, will likely continue to be sensitive to climate change and human impact.…”

Recent global warming is pronounced in high-latitude regions (e.g. northern Asia), and will cause the vegetation to change. Future vegetation trends (e.g. the "arctic greening") will feed back into atmospheric circulation and the global climate system. Understanding the nature and causes of past vegetation changes is important for predicting the composition and distribution of future vegetation communities. Fossil pollen records from 468 sites in northern and eastern Asia were biomised at selected times between 40 cal ka bp and today. Biomes were also simulated using a climate-driven biome model and results from the two approaches compared in order to help understand the mechanisms behind the observed vegetation changes. The consistent biome results inferred by both approaches reveal that long-term and broad-scale vegetation patterns reflect globalto hemispheric-scale climate changes. Forest biomes increase around the beginning of the late deglaciation, become more widespread during the early and middle Holocene, and decrease in the late Holocene in fringe areas of the Asian Summer Monsoon. At the southern and southwestern margins of the taiga, forest increases in the early Holocene and shows notable species succession, which may have been caused by winter warming at ca. 7 cal ka bp. At the northeastern taiga margin (central Yakutia and northeastern Siberia), shrub expansion during the last deglaciation appears to prevent the permafrost from thawing and hinders the northward expansion of evergreen needle-leaved species until ca. 7 cal ka bp. The vegetationclimate disequilibrium during the early Holocene in the taiga-tundra transition zone suggests that projected climate warming will not cause a northward expansion of evergreen needle-leaved species.
