This paper constructs the agricultural water and soil matching model. Taking Liaoning Province as the research object, the situation of utilization of agricultural water resources and land resources were analyzed. The results showed that: Liaoning province is not only the shortage of water resources, and water and soil resources spatial combination difference is very big, The eastern region water resources capacity is much, but in the western region water resources quantity is little . Fushun, Benxi city, and matching with poor is Fuxin city. Water-soil matching coefficient in liaoning province for many years an average of 0.55, below the national average of 1.44. Soil and water matching performance is the time and space distribution is not balanced.

Grain Security

With the growth of population, shortage of water resources, natural disasters, climate change, serious shortage of land resources and the development of urbanization and industrialization and impacts of other unfavorable factors, China's grain security issue has become a focus of public concern. Through the Chinese population quantity analysis and forecast of 2020 and 2030 the total demand of grain, comparison between total demand and current level of food production, China's grain problem is facing tremendous pressure. Water conservancy is the lifeline of agriculture and irrigation has great potential for grain production guarantee. Results for food safety in China made the following responses: First, the rational use of water resources, improve the efficiency of irrigation and grain yield per unit area. Second, multiple sectors such as agriculture, meteorology, soil, make a good combination of multiple disciplines for food security. Third, increase the peasants' production enthusiasm. Last, scientific and technological progress is the guarantee of grain production. In General, the issue of food security is national security, social stability, a top priority. The combination of our country's water resources crisis, limited rational development of agricultural water resources, improve the efficiency of irrigation, which will provide a guarantee for China agricultural water crisis, alleviating the shortage of water resources and increasing food safety assurance.
