西藏农业气候资源评价（1973-1979）
收藏资源简介：
青藏高原的崛起伴随着沧海巨变，促使西南季风和高原季风的形成，显著改变了我国副热带高压带的高温干旱特征，塑造了西藏地区独具特色的农业气候资源。农业气候资源是指在农业生产中可利用的自然能源，包括光、热、水、二氧化碳和风等。在绿色植物的光合作用过程中，光和热提供动力，而水和二氧化碳则作为原料，风则负责输送这些重要成分。因此，地区农业气候资源的丰富程度主要取决于生长季内对植物光、热、水等资源的供给特性，这种特性被称为气候肥力。气候肥力的高低取决于光、热、水等资源的数量、质量及相互协调。西藏的农业气候资源是在其独特自然地理环境条件下形成的，复杂的气候特征使其农业气候资源相对丰富。该数据集以Excel格式存储，包含11张工作簿，涵盖农业气候资源的评价，包括四季划分、太阳辐射强度、不同海拔的光谱组成、水分余亏等内容，是第一次青藏科学考察数据的数字化整理成果，为进一步研究西藏的农业气候条件提供了重要依据。
The uplift of the Tibetan Plateau, accompanied by tremendous climatic and environmental changes, promoted the formation of the southwest monsoon and plateau monsoon, significantly altered the high-temperature and arid characteristics of the subtropical high-pressure belt in China, and shaped the unique agroclimatic resources for Tibet. Agroclimatic resources refer to natural energy sources available for agricultural production, including sunlight, heat, water, carbon dioxide, wind, and others. During the photosynthesis of green plants, sunlight and heat provide energy, while water and carbon dioxide act as raw materials, and wind is responsible for transporting these essential components. Therefore, the abundance of regional agroclimatic resources mainly depends on the supply characteristics of resources such as sunlight, heat and water for plants during the growing season, and this characteristic is called climatic fertility. The level of climatic fertility depends on the quantity, quality and mutual coordination of resources such as sunlight, heat and water. The agroclimatic resources of Tibet are formed under its unique natural and geographical environment, and its complex climatic characteristics make its agroclimatic resources relatively abundant. This dataset is stored in Excel format, containing 11 worksheets, covering assessments of agroclimatic resources including seasonal division, solar radiation intensity, spectral composition at different altitudes, water surplus and deficit, etc. It is the digital collation achievement of the data from the first Qinghai-Tibet Scientific Expedition, providing an important basis for further research on the agroclimatic conditions of Tibet.
