“…The findings indicated that the area with increased NDVI constituted 50.1% of the study area, suggesting an improvement in the vegetation and ecological environment. This finding is consistent with the results of previous studies conducted by Cheng Y., Yudong C., and others [37][38][39]. The research results also revealed that increased precipitation had a positive impact on local vegetation NDVI when the temperature remained stable, leading to a continuous increase in NDVI.…”

Desert farmland provides food for desert areas, but water is the main limiting factor of this region, thus desert farmland has an extremely fragile ecological environment. This study investigated the temporal and spatial variations of vegetation NDVI (Normalized Difference Vegetation Index) in the Ulan Buh Desert, China, from 1990 to 2022, using long-term Landsat satellite data obtained from the Google Earth Engine platform and local statistical data. The results showed that from 1990 to 2022, the NDVI exhibited relatively small fluctuations and a steady increase. Furthermore, the study analyzed the impact of climate factors, namely precipitation and temperature, on NDVI, and collected the groundwater lever changes under irrigation and farmland development. The results demonstrated a positive correlation between NDVI and both precipitation and temperature from 1990 to 2006. The study area experienced an overall trend of increasing humidity. Specifically, from 1990 to 2006, significant positive correlations with precipitation and temperature were observed in 4.4% and 5.5% of the region, respectively. From 2007 to 2022, significant positive correlations were observed in 5.4% and 72.8% of the region for precipitation and temperature, respectively. These findings suggest that temperature has become increasingly influential on vegetation NDVI, while the impact of precipitation remains relatively stable. Moreover, the study assessed the impact of human activities on vegetation NDVI. The results revealed that from 1990 to 2006, human activities contributed to 43.1% of the promotion of local vegetation NDVI, which increased to 90.9% from 2007 to 2022. This study provides valuable insights into the dynamics of vegetation in the Ulan Buh Desert and its response to climatic changes and human activities. The findings highlight the significance of climate conditions and human interventions in shaping the vegetation dynamics in the region, offering essential information for ecological restoration and conservation efforts.

“…Due to the influence of climate warming, along with prolonged droughts and overgrazing, the grassland in Inner Mongolia has suffered serious degradation, and approximately 90% have been degraded over a few decades (Akiyama & Kawamura, 2010;Shao, Chen, Zhang, & Huo, 2017), which led to myriads of environmental and economic problems, such as deterioration of biodiversity and ecosystem function and services and the aggravation of sandstorms, desertification, and poverty (Han et al, 2018a;Qi, Chen, Wan, & Ai, 2012;Shao & Dong, 2006). To mitigate grassland degradation and to promote the restoration of grassland ecosystems, a series of national grassland protection projects have been implemented in Inner Mongolia since 2000 (Jixia, Qibin, Jing, Depeng, & Quansheng, 2018;Li & Qin, 2014), for example, the Beijing-Tianjin Wind/Sand Source Control Program (BTWSSC), the Grazing Withdrawal Program, the Ecological Subsidy and Award System (ESAS), and the Natural Forest Protection Project (NFPP) (Dang, Li, Li, & Dou, 2018;Deng, Zhang, Cheng, Hu, & Chen, 2019;Feng, Tian, Yu, Yin, & Cao, 2019;Hua, Huang, & Li, 2019;Wang, Zhao, Fu, & Wei, 2019). In 2004, key ecological construction projects were first developed, and numerous studies have shown that the implementation of such projects has improved the ecological integrity of some areas of Inner Mongolia, although others are still being degraded (Cao, Liu, & Yu, 2018;Han, Song, Deng, & Xu, 2018;Yin, Hou, Langford, Bai, & Hou, 2019;Zhou & Zhao, 2017).…”

Assessing the degradation of grassland ecosystems based on the advanced local net production scaling method—The case of Inner Mongolia, China

The gradual degradation of grasslands on a global scale goes hand‐in‐hand with significant challenges for agriculture and animal husbandry development. Numerous relevant policies and projects have been implemented to protect and restore Chinese ecosystems, but it is still unclear to what degree grassland ecosystems can be recovered. In view of this, we constructed an advanced local net production scaling (ALNS) method by replacing the classification method by self‐organizing feature maps (SOFM) and tailoring the ideal state evaluation method in the LNS method. The ALNS method is used to analyze differences within grassland ecosystems, explore the ideal state of grassland ecosystems, and define degradation as the degree to which the actual state deviates from the ideal state, representing the degree to which grassland ecosystems can be recovered. It thereby quantifies and assesses the overall degradation of such systems in Inner Mongolia. Based on the results, more than 98.5% of the total grassland area failed to reach the ideal state, with the highest levels in the northeast with DN (degraded net primary productivity) values exceeding 200 gc/(m2·yr), followed by the midlands with DN values from 50 to 200 gc/(m2·yr) and the southwest with DN values between 0 and 150 gc/(m2·yr). The ALNS method can efficiently assess grassland ecosystem degradation and can be used to indicate the deviation degrees from ideal states, facilitating the development of protection and restoration programs for grassland ecosystems.
