Abstract:

The aim was to predict the population capacity level of cultivated land scientifically. This paper was a case study of the fieldwork in Pixian which was based on the accounting production capacity. It formed the cultivated land production capacity dynamic prediction model and land capacity model, then divided the region of population supporting capacity, made an holistic analysis on pixian’s Population supporting capacity of land. The results showed that: (1) the cultivated land production capacity of Pixian was 505718 t, and the population supporting capacity was large in the coming years. But it distributed uneven, and the largest capacity difference between countryside and town could be 194377. (2) Economical advanced area such as Xipu, Pitong, Hongguang, the population supporting capacity was small. The contradiction between land and population was serious. SR was more than 0.90. (3) According to the empirical study measuring method in line with the actual local, was objective and scientific.
