Lucid waters and lush mountains are invaluable assets. The Sichuan Tibetan areas，which is defined by the state as the national key ecological function area，undoubtedly play an important role in poverty alleviation and reduction through ecological protection and construction. In order to consolidate the key achievements of poverty alleviation and cope with the more complex relative poverty，it is undoubtedly of special significance to refine the unique eco-poverty reduction model of the region，give full play to the comparative advantages of the ethnic areas with important and fragile ecological environment，and improve the ability of lucid waters and lush mountains to transform into gold and silver mines and to get rid of poverty. Starting with the specific cases of eco-poverty reduction in Tibetan areas，this paper analyzes the theory，method and prospect of eco-poverty reduction from the three dimensions of theoretical logic，practical model and evolution direction，and puts forward specific poverty reduction modes such as “ecological compensation”，“eco-tourism”，“ecological industry”，“ecological migration”，“e-commerce” and “photovoltaic power generation”. The research attempts to infuse new contents into the theoretical research of poverty governance in ethnic areas，to provide the typical empirical analysis samples for the farmers and herdsmen to solve the poverty problem，and to provide the referential and easy-to-operate toolbox and method base for the governance of relative poverty in China and even in the world.
