Based on characteristics of ecologic environment and ecologic economy, energy resource use in the Manas River Basin of Xinjiang Wei Autonomous Region is calculated using the energy method.The calculation shows that the energy self-sufficiency ratio is 98.06%,and the renewable resource energy ratio,65%,which indicate that mountain and desert are the main ecologic conditions to support the development of ecological economy.The total amount of energy use is 5.20×10²² Sej/a,imported energy ratio,13.46%,energy investment ratio,0.09,and energy per person, 1.12×10¹⁰ Sej/a,all of which are lower than the world levels.Energy use intensity is only 1.22×10¹¹ Sej/a,environment load,only 12.2,and energy yield ratio,1.22, which show that resource development intensity is weaker,and environment load is lower.Therefore,while developing ecologic economy in the oasis based on regional characteristics and fine resources of low value energy,the key rare energy resources with high value must be introduced,and feedback support and trade output of high value energy products must be strengthened.While consolidating energy foundation,the attention must be paid to energy use and its transformation potential.
