Effects of Drought on Plant Phenology in China
Plant phenology, which reflects seasonal changes in plant growth, is a vital indicator of the impacts of climate change. Drought, as a recurring natural phenomenon, has disastrous effects on plant phenology as it can lead to stunted plant growth, reduced greenery, and increased plant mortality. Therefore, understanding how drought affects plant phenology in regions such as China, which has the largest agricultural area in the world, is critically important. China has experienced a decade of recurring drought, affecting agricultural ecosystems and vital resources, and thus this topic must be addressed in depth.
While
previous studies focused on examining the spatiotemporal relationship between drought indicators and the Normalized Difference Vegetation Index (NDVI). However, this index alone cannot capture the specific physiological indicators of plants. Therefore, using direct phenological indicators, such as the Start of Growing Season (SOS), End of Growing Season (EOS), and net primary productivity rate, provides better insights into understanding the effects of drought on plant phenology. For example, prolonged drought periods can delay both SOS and EOS, impacting the productivity efficiency of plants and the ecological balance in the environment.
In summary, drought disrupts the growth cycle of plants, negatively impacts the food chain, and disturbs the carbon balance in ecosystems. Thus, investigating this topic requires an in-depth analysis of the climatic and geographical factors affecting plant phenology’s response to drought.
Temporal and spatial response to drought in China
In recent years, studies on the response of plant phenology to drought in China have proliferated, confirming the existence of complex and diverse responses. Drought can cause delays in harvest or accelerate plant growth in some agricultural areas, heavily depending on the region and type of ecosystem. For instance, in dry northern regions, significant declines in crop productivity have been reported due to the negative effects of drought. Meanwhile, in the more humid southern regions, long-term drought periods may lead to negative changes in growth timings, potentially resulting in changes in flowering times or even reduced production rates.
Extreme weather events in these contexts have heightened the importance of the study, as the effects of climate change have intertwined with historical drought factors, making it essential to understand how agricultural strategies can adapt to this new situation. Based on assessments of heat monitoring and water deficiency, researchers have questioned whether current agricultural systems rely solely on natural water resources or need new technologies and more sustainable farming methods.
These challenges include the necessity to improve planning and management of water resources, along with enhancing understanding of how ecosystems respond to emerging climatic stresses. By assessing the drought index known as PDSI (Palmer Drought Severity Index), the spatiotemporal patterns of drought can be determined over a specific timeframe, enabling researchers to assess changes in plant phenology and plan appropriate responses.
Drought as a factor influencing plant phenology
It is well known that drought plays a pivotal role in shaping the behavior of plants temporally and spatially. As climate change intensifies, optimal conditions for plant growth are subject to unprecedented changes, increasing the significance of drought as an influencing factor. Studies indicate that drought affects not only the timing of the start and end of the growing season but can also lead to changes in the carbon content of plants, which subsequently impacts the climate overall. This reflects how plant phenology can be a solution in understanding climate changes and guiding environmental policies.
For instance, some studies have demonstrated that various environmental models agree that high drought-associated temperatures linked to climate change will advance the start date of the growing season for some plant species. Conversely, in certain environments, drought may lead to delays in recovery and biomass production, negatively impacting local agriculture. Therefore, farmers and agricultural planners must consider the sharp differences in plant species’ responses to drought, which may require diverse agricultural techniques and careful monitoring of drought conditions.
In summary,
In general, the impact of drought on plant phenology requires a multidisciplinary response, including agricultural practices, water management strategies, and risk management related to climate change. By integrating these aspects, countries can enhance the ability of ecosystems to cope with the impacts of drought.
