Description
The mountainous grassland in the southern part of Gansu province of China, which is located between 33°06'-35°29'N and 101 °60' -103°E, lies on the northeastern border land of the Qinghai-Xizang plateau. On the north, it is contigiuous to loess plateau, on the south it borders on Chuan-xi plateau. The eastern part of the grassland belongs to Lung-nan mountainous area. The terrain of the region slopes from south to north. On the south of the area, stand Ji-shi mountains, in the middle and on the north stand Xi-qin mountains. The large part of the region is 3.000 metres above sea level. The region and its climate are all plateau types with cold and moist lower atmospheric pressure. The temperature in the hottest month averages below 15° C. The absolutely lowest temperature is around - 20° C. The precipitation each year is 500-600 mm and the relative humidity of atmosphere reaches 70 % . With these environmental factors, a moor grassland has been formed on both the low lands of wartershed and between the mountains in the south of the region. On the large area of the mountainous region and the hilly land in front of the mountain grows a cold-resistant meadow. In the west, on the hill-side at the upper reaches of Daxia river, Picea wilsonii is distributed far and wide ; on the sunny hill-side grows a shrub grassland.
