近50年安徽省氣候生產潛力演變及糧食安全氣候承載力評估
[Abstract]:Anhui Province is an important grain producing area, which plays an important role in ensuring the food security in China. It is of great practical significance to study the evolution characteristics of the climatic production potential of Anhui Province and to analyze its climate carrying capacity in the face of grain security. Based on the relationship between grain production and climatic factors, such as light, temperature and water, this paper calculates the climatic production potential and its changing characteristics of Anhui Province by using the method of step by step correction, and according to the grain demand index under different living standards, The climate bearing capacity and remaining space of Anhui Province are analyzed. The results show that the climatic potential of Anhui Province is distinguished by geographical differentiation, in which the northern part is higher than the south, the plain is higher than the mountainous area, and the high value area is mainly located along the Huaihe River and the Huaibei region, which is in good harmony with the cultivation conditions. The climatic production potential of the province from 1961 to 2013 showed a decreasing trend, which decreased by about 10. 5% in the last 50 years. At present, the grain consumption level and structure of Anhui Province belong to the transition period from the type of food and clothing to the type of Xiao Kang. On the premise of giving full play to the potential of climate production, the grain output that the climatic resources can carry in Anhui Province is significantly higher than the total demand under different living standards. At the well-off level, the relative residual rate of climate carrying capacity is decreasing from northeast to southwest. Except for some urban areas and mountainous areas, the remaining space of climate carrying capacity in most areas of the province is still relatively rich, which can better ensure the food demand. On the whole, due to the better coordination of light, warm water and cultivated land in Anhui Province, the climate bearing capacity is relatively high. Although the climate production potential has declined in recent years due to the influence of solar radiation, it is in terms of ensuring food security in a well-off society in the future. Anhui Province still has a good climate bearing capacity, grain production has a greater room for improvement.
