Abstract

By analysis of the classical research achievements of physical potential productivity and famous agro-laws on  social-economic factors since the 1960s in China, this paper presented relative systematic indicators on the integrated agricultural potential productivity. According to the main environmental factors relateded to plant growth and grain yield, the authors selected sun-light, heat, precipitation and soil as the key indicators to establish a system of physical potential productivity, and then according to the eight factors of soil cultivating, fertilization, irrigation, species improving, efficient planting, pest controlling, land management, and instrument improving in China, established a system of social-economic potential productivity. Based on these indicators, the authors introduced some amendment parameters of the main socio-economic factors to correct and revise the existing typical agricultural physical potential productivity models. The search results on integrated agricultural potential productivity indicator system and model may provide an effective tool to assess quantitatively on the utilization degree of agricultural resources.

Key words： agricultural productivity；indicator system；physical potential productivity; amendment parameter；integrated model
