Abstract
According to the actual food production of various types of ecosystems (cropland, grassland, aquatic, forests) in Chengde and the food nutrition conversion table, if we convert various types of food into three major nutrients (heat, protein, fat) needed by the survival of humans, we come to the actual food supply capacity in Chengde. The results show that: The supply of the three major nutrients is enough, but the supply capacity is different. With corn and pork as the main source of food supply, the food supply structure is inconsistent to the consumption structure. The contribution of cropland accounts for the vast majority; the proportion of food supply from grassland is much higher than that of China; the proportion of food supply from aquatic is low, with an average of 0.53 %; the proportion of food supply from forests is growing fast. The per capita food supply capacity of three major nutrients from cropland in Chengde is lower than that in China, with that from grassland far higher and that from aquatic far lower. We should adjust and optimize the industrial structure, improve the nutrition structure, and the living standards in Chengde.
