摘要
The agro-pasturage ecotone in northern China is not only an important green ecosystem barrier but also an important economic belt. However, the extensive operation manner and harsh natural surroundings lead to the grassland degradation, low agricultural productivity and people living in poverty. In our study, the result has shown that the aboveground biomass and economic benefits of improved grassland, artificial perennial grassland and silage farmland have been increased greatly. Therefore, the development and construction of high-yield silage farmland and artificial perennial grassland in agro-pasturage ecotone not only increase the economic benefits but also protect the ecological environment.
