On the basis of accounting results of agricultural production capacity in Guangdong Province, the paper analyzed the spatial patterns of natural productivity use potential(future productivity potential) and reality productivity use potential(short-term productivity potential) under the five Typical Areas in Guangdong Province, and according to the cultivated land gradation results and factor differentials & correlation coefficient of the participating factors ,it explored the main impact factors for promoting the production capacity potential of typical areas in near future. The results showed that the most high-value areas of use intensity and the minimum value areas of use potential in the Northern of Guangdong province and in the Chaozhou-Shantou region, especially in latter region where there was hardly any potential in some places, and meanwhile the more promoting potentials area was in Luichow peninsula region,Central-south and Southwest of Guangdong province. Therefore, ensuring probability of agricultural irrigation was an important way to increase cultivated land production capacity in the future in Luichow peninsula. Renovating farmland infrastructure was a main way to increase production capacity in central south and southwest of Guangdong province, and improving the soil pH and increasing soil fertility were also the effective ways in above regions; it could increase cultivated land production capacity through improving organic content, agricultural irrigation and farmland slope in the northern of Guangdong province;Production capacity could be partly increased by improving salinification along the coast in the Chaozhou-Shantou region .
