Abstract:: In order to better evaluate the situation of solar energy resources utilization and sustainable development of agriculture at county level in Tibetan areas of Yunnan, quantitative analysis of energy input and output, environmental carrying capacity and operation results of agricultural ecological system in Shangri-La County has been carried out by using enrgy analysis method. The results show that the net output of agricultural ecosystems energy of the study area is 342.66, energy input rate is 0.01, energy density is 3.49×10¹¹ sej/m²; the mean consumption of energy per capita is 2.32×10¹⁶ sej /people, energy yield percapita is 8.42×10¹⁶ sej; the environment contribution rate, renewable resource input ratio, nonrenewable resource investment and nonrenewable industrial auxiliary energy investment rate are 98.97, 97.34, 1.63 and 1.03, respectively; environmental capacity is 0.027; the energy based sustainability development index is 12 691.11. The results also show that agricultural economic development is relative backwardness, and the sustainable development ability is weak. In order to promote agricultural economy and strengthen the agricultural sustainable development ability, Shangri-La County should increase inputs of high grade ability energy, adjust the energy investment structure quickly and accelerate to change agricultural development mode.
