Based on the researches on ecological land from scholars, the paper defined the concept of ecological land from the perspective of ecosystem service function. According to the degree of hemeroby, the classification system of the ecological land was constructed. Meanwhile, the gap between the ecological land classification and land use classification was connected. The ecosystem services value of the ecological lands all over China was evaluated and its variation characteristics were analyzed. The results shows that: 1) Ecological land in a broad sense refers to land types which can supply, regulate, support ecosystem services, and play an important role in maintaining regional ecological balance and regulating global climate. 2) Based on the degree of hemeroby, the ecological land was divided into three level-one categories (non-interference ecological land, semi-interference ecological land and full disturbance ecological land), five level-two categories and 31 level-three categories. 3) In 2012, the ecosystem services value of the ecological land in China was 28 048 380 million yuan, and the spatial pattern was “the highest in the west, lower in the middle, and the lowest in the east”. The national ecological services value from 2009 to 2012 showed a downward trend. There was great spatial variation of the change that increase appeared in the central region and decrease appeared in the east and the west. During 2009-2012, all kinds of ecosystem services functions of ecological land were damaged and were declined year by year, suggesting that the ecosystem stability is low. %U https://www.jnr.ac.cn/EN/10.11849/zrzyxb.20161400
