ENERGY ANALYSIS OF UPLAND CROP COMBINATIONS IN THE YIBIN DISTRICT OF SICHUAN PROVINCE
On the principle of systematic input and output, the energy flow and conversion in upland crop combinations in the Yibin district of Sichuan province was analysed, and the duster analysis of the types was carried out The development in the future was also suggested in this paper.
