The wheat ripening process is divided into the milk stage, the waxy stage, and the full maturity stage. The final harvest standard for wheat is determined by the degree of maturity of the grains. Generally speaking, the harvest standard for wheat is the grain moisture content, and the general safe storage standard is 12.5%, although this indicator may vary slightly depending on the variety. In practice, wheat is often harvested when it reaches about 90% maturity.

Land surface temperature (LST), as a key physical quantity driving the exchange of matter and energy between the Earth's surface and the atmosphere, plays a crucial role in numerous fields, including climate change, environmental monitoring, evapotranspiration estimation, and geothermal anomaly exploration. As a key parameter for studying regional and global-scale land surface physical processes, LST directly participates in the calculation of related models such as global circulation models and surface parameters such as latent heat flux, sensible heat flux, and soil heat flux. LST is widely used in meteorology, geology, hydrology, ecology, agriculture, and urban heat island research. Particularly in the agricultural environment, LST is a fundamental parameter in many soil moisture and agricultural drought monitoring models. Therefore, timely and accurate acquisition of the spatiotemporal distribution of land surface temperature is vital for explaining and understanding global climate change.

On November 17, 2023, a delegation of six people led by Zhou Dongming, Director of the Standing Committee of the Anqing Municipal People's Congress, visited Xi'an Xi'an Institute of Optics and Precision Mechanics CAS Aerospace Science and Technology Group Co.,LTD Technology Co., Ltd. for inspection and exchange. Qin Jing, General Manager of Xi'an Xi'an Institute of Optics and Precision Mechanics CAS Aerospace Science and Technology Group Co.,LTD Technology Co., Ltd., Wang Yantian, Deputy General Manager, and relevant personnel warmly received the delegation and accompanied them on their inspection.

On-board hyperspectral images are due to theirHigh spectral resolutionandLarge-scale spatial coverageHyperspectral targets have significant applications in tasks such as ground feature identification, urban monitoring, agricultural surveys, and environmental assessment. However, this type of data typically features numerous spectral bands, large target scale variations, complex backgrounds, and scarce labeled samples, making target detection tasks highly challenging. Traditional spectral matching and statistical feature methods struggle to simultaneously process spectral and spatial information, resulting in limited effectiveness for detecting small targets and complex backgrounds. In recent years, the development of deep learning technology has provided a new solution for on-board hyperspectral target detection. By automatically extracting spectral-spatial features through end-to-end training, it significantly improves the accuracy and robustness of detection.

In March 2021, General Secretary Xi Jinping emphasized at the Ninth Meeting of the Central Financial and Economic Affairs Commission that achieving carbon peaking and carbon neutrality is a broad and profound systemic transformation of the economy and society. He stressed that carbon peaking and carbon neutrality must be incorporated into the overall framework of ecological civilization construction, and that resolute efforts must be made to achieve the goals of carbon peaking before 2030 and carbon neutrality before 2060 on schedule. These "dual carbon" goals are a solemn commitment my country has made to the world, demonstrating China's firm determination to actively address climate change, pursue a green and low-carbon development path, and promote the common development of all mankind.

From October 26th to 29th, 2023, the four-day 2023 Xi'an Unmanned Aerial Vehicle (UAV) Conference was held at the Xi'an Aerospace Base General Airport. The conference, themed "Innovation Connects the Future, Integration Unleashes Dreams," aimed to promote exchange and cooperation among UAV R&D, production, and application units, create a more favorable environment for UAV development, and promote the high-quality development of the UAV industry.

Inland water bodies are an important component of the natural ecosystems upon which humankind depends for survival and development, playing an irreplaceable role in water supply, drought and flood control, transportation and navigation, climate regulation, providing habitats for organisms, and maintaining biodiversity. In recent years, under the influence of human activities and climate change, inland water resources, the water environment, and aquatic ecosystems have faced varying degrees of problems and threats. Eutrophication and the resulting algal blooms are prevalent pollution problems in inland water bodies, and the steady-state balance between watershed development and ecological coordination has gradually received attention from relevant departments.
