This paper used a new method of theory model of earth-air radon transportation and the formula of radon exhalation rate to dope out the atmosphere radon consistency and calculate the area geological potential,which is different from the tradition method of converse the airborne Gamma-ray spectrometry data into the absorbent dose rate on earth(1m above).

The research of radon geological potential is an important part of environment radon research and an effective approach of fast evaluating radon level from geology.

Based on the natural land conditions of Da Dou Pu township,adopted the agriculture Eeo-division, the photosynthesis potential, temperature potential, rainfall potential and soil potential were estamited and analyzed comprehensively.

Greenhouse gases exchange of integrated paddy field and their comprehensive global warming potentials;
