Quantitative Assessment of Climate Change Impact and Anthropogenic Influence on Crop Production and Food Security in Shandong, Eastern China

Food security plays an important role in maintaining national stability and sustainable development of human society, its research has become a hot issue at present. Shandong is the main grain producing area China, production food security. Accordingly, this paper based on county climate change, yield, sown area, fertilizer use, total power rural machinery, population data Province from 1995 to 2020. The evolution process pattern was studied by methods spatial analysis comprehensive evaluation, influencing factors were quantitatively analyzed, adaptive countermeasures alleviate risks region discussed. results show that: Grain increased 30.62% per capita availability also increased. Since 2000, more than quarter counties have experienced high risk insecurity. agglomeration enhanced, local characteristics significantly different. average temperature growing season, agricultural machinery had significant positive impact production, while annual negative production. Improving supply system, strengthening protection cultivated land, improving efficiency utilization, increasing investment science technology can effectively risks.
