[Keerqin], Jirem [Zhelimu], and Songnen Plains, northeast of Chifeng and east of the Daxinganling Mountains (Map 1-3). The regional vegetation map of China (Map 1-2) shows that these grazing areas extend well into the adjacent Liaoning, Jilin, and Heilongjiang provinces.
The climate of the steppe region of China is cold and dry in winter and relatively warm in summer. Figure 3-1, a Klimadiagram for Chifeng City, shows five months of the year with a mean temperature of less than 0°C. The forest steppe zone differs from the other steppe regions by having more total rainfall, particularly summer rainfall, thereby contributing to potentially higher biological productivity. Jiang Fengqi (1984), professor at the Institute of Applied Ecology in Shenyang, demonstrates the relationship between the higher
