为揭示林芝地区农业生态经济系统内种植业、畜牧业、林业、渔业各组分的构成情况及能值演替的基本趋势，应用能值分析理论与方法，定量分析西藏林芝地区2006－2010年农业生态经济系统的投入产出状况、环境负载率和可持续发展指数。结果表明：西藏林芝地区2006年农业总投入能值为2．29E＋20sej，总产出能值达1．74E＋20sej，可持续发展指数为1．25；2006－2010年农业总投入能值呈急速上升趋势，总产出能值则缓慢上升，可持续发展指数表现为下降趋势，林芝地区的农业发展已由可持续逐渐向消费型农业生态经济系统转变。林芝地区农业经济发展的科技含量不高，是一种消耗高、产出低的发展模式，资源浪费较严重，农业生产效率低。

To reveal the basic trend of planting,animal husbandry,?forestry,and fishing industry components and energy succession in agricultural ecological system in Nyingchi area,applying emergy analysis theory and method,the authors quantitatively analyzed input-output status,environmental load ratio and sustainable development index in the agricultural ecological system during 2006-2010.Results:The gross input emergy,gross output emergy and sustainable development index in 2006 were respectively 2.29E+20sej,1.74E+20sej and 1.25;During 2006-2010 the gross agricultural input emergy showed a sharp increasing trend,and total output emergy increased slowly,whole the sustainable development index showed an decreasing trend,the agricultural development in Nyingchi area changed from sustainable agriculture to consumption type agricultural ecological economic system gradually.The content of science and technology development of agricultural economy in Nyingchi is not high,and is the development mode of a kind of high consumption and low output,low content of science and technology in the production process,serious resources waste and low efficiency of agricultural production.
