文摘内容 After the analysis of food security of Shandong Province since 1990s, based on the change of grain output and per unit grain yield, it was considered that food production of Shandong Province was generally stable; through comparing the proportion of per capita possession of grains and per unit grain yield of Shandong Province in the whole country, it revealed that they were higher than the national average level. On this basis, the relationship between land-water resources and food security had been analyzed, and it summarized that Shandong water resources were insufficient, agricultural water was not enough and water had been seriously polluted; and that cultivated area was large and the overall quality was high. Meanwhile, it had analyzed the spatial pattern of land-water resources and the loss of water and soil. Finally, suggestions for the sustainable use of land-water resources in Shandong Province based on food security had been proposed. It should enhance the construction of basic agricultural facilities and implement united dispatching of multiple water resources; strengthen the supervision of cultivated land resources and comprehensively develop reserve resources of cultivated lands; and intensify the treatment of land-water resources and prevention of the loss of water and soil in key areas.
