Discussion on the development of cropgrass system in the Three Rivers region of Tibet

Grassindustry in agricultural area (threerivers region) must be developed in Tibet so as to adapt to the Tibetan development in the future. In double cropping system of threerivers area, the introduction of fodder production could adjust agricultural structure and waterheat pattern, and make the agricultural system more reasonable and environment conservation. Fodder production and grass growing could provide a lot of high quality forage for livestock production, and enhance vegetation coverage, reduce wind speed and soil loss. The development of grassindustry in agricultural area could alleviate the great livestock pressure in natural rangeland and slow down the grassland degradation. The development of fodder and livestock production industry could benefit the construction of special bases for livestock production, the economic development and then the income of herders. Therefore, grass system development in agricultural area was a key point to improving the sustainable development in threerivers region.
