“…Advance in SOS has been shown to increase spring gross primary production (GPP) and biomass and net primary production across most of the QTP; the delay in EOS could facilitate increased autumn GPP, biomass, net primary production, and evapotranspiration, as well as water use efficiency 50,56,141,[165][166][167][168][169] . In a semi-humid alpine meadow in the north-eastern QTP, warming-induced advance in spring phenology increased the temperature sensitivity of ecosystem respiration 170 , leading to increasing loss of carbon.…”

Start of growing season advanced by 9.4 ± 2.2 and 8.3± 2.0 days during 1982-1999 and 2000-2020 respectively, whereas its end delayed only by 8.2 ± 1.9 days during 2000-2020.Current models project an advance in season start by 8.8 days and a delay in season end by 14.0 days in 2086-2100 relative to 2000-2014 under Shared-Socioeconomic-Pathway 5-8.5. Warming and increasing precipitation are the main climatic drivers of advancing spring phenology (start of vegetative growing season and first flowering) and delaying end of the growing season. The direction and magnitude of responses of phenophases to temperature depend on soil water availability, with greater temperature sensitivity of the start and end of the season under wetter conditions.First flowering date is more sensitive to temperature on the Qinghai-Tibetan Plateau than in Arctic grasslands.The temperature sensitivities of the start and end of the growing season are greater than those of Arctic grasslands, but smaller than those of mid-latitude alpine and subalpine grasslands.

“…From different parts of the country, the timings of leaf-out and fruit-set significantly advanced in Qinghai Tibet Plateau in recent years [16,17]. In recent decades, warming in Inner Mongolia Plateau has been much faster than the global warming rate [18], and the increase of temperature impacts grassland phenology significantly [19].…”

Response of Biodiversity, Ecosystems, and Ecosystem Services to Climate Change in China: A Review

2021

Climate change is having a significant impact on the global ecosystem and is likely to become increasingly important as this phenomenon intensifies. Numerous studies in climate change impacts on biodiversity, ecosystems, and ecosystem services in China have been published in recent decades. However, a comprehensive review of the topic is needed to provide an improved understanding of the history and driving mechanisms of environmental changes within the region. Here we review the evidence for changes in climate and the peer-reviewed literature that assesses climate change impacts on biodiversity, ecosystem, and ecosystem services at a China scale. Our main conclusions are as follows. (1) Most of the evidence shows that climate change (the increasing extreme events) is affecting the change of productivity, species interactions, and biological invasions, especially in the agro-pastoral transition zone and fragile ecological area in Northern China. (2) The individuals and populations respond to climate change through changes in behavior, functions, and geographic scope. (3) The impact of climate change on most types of services (provisioning, regulating, supporting, and cultural) in China is mainly negative and brings threats and challenges to human well-being and natural resource management, therefore, requiring costly societal adjustments. In general, although great progress has been made, the management strategies still need to be further improved. Integrating climate change into ecosystem services assessment and natural resource management is still a major challenge. Moving forward, it is necessary to evaluate and research the effectiveness of typical demonstration cases, which will contribute to better scientific management of natural resources in China and the world.

“…(2) Research on the process of grassland ecosystem management [5,16,50,55,103], including grassland degradation and restoration, stocking capacity estimation, crude protein content estimation, and alien species invasion monitoring. Studies have focused on nitrogen, carbon, and water cycle processes in grassland [4,16,104], and phenology is also an important research topic [5,8,9,22,74,105,106]. Most of the early grassland resource research did not classify grasslands or distinguish dominant species, poisonous weeds, etc.…”

Grassland remote sensing (GRS) is an important research topic that applies remote sensing technology to grassland ecosystems, reflects the number of grassland resources and grassland health promptly, and provides inversion information used in sustainable development management. A scientometrics analysis based on Science Citation Index-Expanded (SCI-E) was performed to understand the research trends and areas of focus in GRS research studies. A total of 2692 papers related to GRS research studies and 82,208 references published from 1980 to 2020 were selected as the research objects. A comprehensive overview of the field based on the annual documents, research areas, institutions, influential journals, core authors, and temporal trends in keywords were presented in this study. The results showed that the annual number of documents increased exponentially, and more than 100 papers were published each year since 2010. Remote sensing, environmental sciences, and ecology were the most popular Web of Science research areas. The journal Remote Sensing was one of the most popular for researchers to publish documents and shows high development and publishing potential in GRS research studies. The institution with the greatest research documents and most citations was the Chinese Academy of Sciences. Guo X.L., Hill M.J., and Zhang L. were the most productive authors across the 40-year study period in terms of the number of articles published. Seven clusters of research areas were identified that generated contributions to this topic by keyword co-occurrence analysis. We also detected 17 main future directions of GRS research studies by document co-citation analysis. Emerging or underutilized methodologies and technologies, such as unmanned aerial systems (UASs), cloud computing, and deep learning, will continue to further enhance GRS research in the process of achieving sustainable development goals. These results can help related researchers better understand the past and future of GRS research studies.
