I. Introduction.
Food security is a major issue related to the national economy and people's livelihood. As a country with a large population, it is very important for our country to ensure national food security. In recent years, China has attached great importance to agricultural development and clearly proposed to improve land grain production capacity. This paper will start from the current situation of land resources in China, analyze the ways to improve land grain production capacity, and combine policy support and practical results, as well as the challenges and coping strategies.
2. The current situation of China's land resources.
Total land resources: China has abundant land resources, but the per capita occupancy is small.
Land use: cultivated land, forest land, grassland and other land types are complete, but the area of cultivated land is decreasing year by year.
Distribution of land resources: The distribution of land resources in the eastern, central and western regions is uneven, and land resources are tight in some areas.
3. Ways to increase the grain production capacity of the land.
Scientific and technological innovation: increase investment in agricultural scientific research, and promote high-yield, high-quality, stress-resistant, and adaptable crop varieties.
Adjustment of planting structure: According to the characteristics of land resources, optimize the planting structure and develop marketable agricultural products.
Green development: Promote water-saving irrigation, soil testing and formula fertilization and other technologies to improve the efficiency of agricultural production.
Fourth, China's policy support and practical achievements.
Policies and measures: Implement the construction of grain production functional zones and important agricultural product production protection areas, and increase agricultural subsidies.
Practical results: China's grain output has grown steadily for many years, and food security has been effectively guaranteed.

5. Challenges and coping strategies.
Challenges: Shortage of land resources, deterioration of the ecological environment, and rising agricultural production costs.
Coping strategies: strengthen scientific and technological innovation and improve the efficiency of agricultural production; optimize the policy system to protect the interests of farmers; Promote green development and achieve sustainable agricultural development.
VI. Conclusions. Through scientific and technological innovation, policy support, green development and other efforts, China has achieved remarkable results in improving land grain production capacity. However, there are still challenges to be addressed, such as the shortage of land resources and the deterioration of the ecological environment. Only by continuously promoting agricultural modernization can we ensure national food security.
