| Abstract: | During June and July 2003, the natural vegetation was studied in Dongfeng gully of Waxie township, Ning Xian county, Gansu province, on the Loess Plateau. With integrated data investigation, the healthiness of the ecosystem and the degeneration degree of the grassland was estimated based on the theory of grassland resource investigation and programming. Then recommendations on improvement and restoration of this degenerated ecosystem and the recommendations on grassland reclamation from farmland to promote regional climate were made. With inquiry to Expert System of China grassland agriculture, which provide expert suggests by modules called Planting of Pasture and Synthesize Gradation of Grassland, and compared with experimental data the analyse of the suitability of pastures was given out. |
