Multi-Scale Evaluation of Dominant Factors (MSDF) on Forage: An Ecosystemic Method to Understand the Function of Forage

Grassland agroecosystem plays a key role on resource cycling and sustainability of global ecosystem. Forage is the basic factor core grassland agroecosystem. At single scale, most forage evaluation remain in state qualitative or quantitative evaluation, lack series at multi spatial scales influence society, environment economy. This study collected dominant indicators micro, plot, farm, ecoregional macro to compile systemic agroecosystems. A case presented for by using regional data from an arid region Gansu, China. Multi-scale factors (MSDF) was used aggregate indicators. Results showed that scale had significant effects results evaluation. The index same species among farm were different. implied MSDF are needed guide then production herbivore future. An appropriate could be selected term objectives moreover, should improve environmental, social productive
