Suggestions for grassland ecosystem protection and development in Heilongjiang province

摘要：

The grassland areas of Heilongjiang Province occupy 433.2 × 104 ha,and are mainly distributed in the northwestern Songnen Plain, eastern Sanjiang Plain and mountainous area of Daxinanlin, Heihe in the east‐north.Types of grassland are dry steppe, steppe subpratensia, meadow, swamp meadow and slough ( Soil Compilation Committee of Heilongjiang Province, 1994).Grassland utilization and stockbreeding in Heilongjiang Province lagged behind other provinces.But, rapid development and an increase in grassland stockbreeding in recent years caused grassland to degrade and eco‐functions to decrease.So it is important to protect and develop grassland ecosystems.
