physical geography

River water resources

① The water resources in Xianyang City are mainly composed of river runoff and groundwater. The average self-produced surface runoff in the city for many years is 543 million cubic meters, the groundwater does not repeat 366 million cubic meters, and there are 6.079 billion cubic meters of inbound passenger water. Atmospheric precipitation is one of the main sources of surface runoff and groundwater recharge. The average annual rainfall is 567.9 mm, and the total annual rainfall is 5.86 billion cubic meters. The distribution of annual precipitation in various places shows the general trend of less in the south and more in the north.

② The water system belongs to the Weihe River system in the Yellow River Basin. The main stream of Weihe River flows out from the southern edge, and the main tributaries flowing into the urban area are Qishui River, Xinhe River, Fenghe River, Jinghe River and Shichuan River, among which Jinghe River is the largest, forming two major water systems, Jinghe River and Weihe River. Rivers and canals 158, with an area of 100 km2, and 26 rivers with an area of 100 km2.

(3) The groundwater resources are abundant, and the total water resources are 65,438+0,654,38+0.3 billion cubic meters. There are 12 hot springs and 9 hot water caves. The per capita possession of water resources is 20.5% at the provincial level and 9.8% at the national level. It embodies the distribution law of the rich in the south and the poor in the north. Groundwater in South China is the main part of groundwater, which is widely distributed, except for some rocky hills, but the water abundance is quite different. Due to the rapid alternation of circulation, the diving is shallow, easy to develop, easy to adjust and store. However, due to the continuous drought in recent years, insufficient surface water supply and over-exploitation of groundwater, the water level has continued to drop, and even some rivers and ponds have dried up. In a word, the city is rich in water resources, but the per capita possession and arable land per mu are low, accounting for 15.2% and 13.6% of the province respectively, ranking ninth among the ten cities in the province. There is a lot of transit water, but it is difficult to use. The distribution of surface water and groundwater is extremely unbalanced.

land resources

The total land area of the city is 10 19600 hectares, which can be divided into four categories according to the geomorphological characteristics: rocky mountains, hills, original sites and Sichuan roads. The soil distribution in Xianyang city belongs to the transition zone from the shrub cinnamon soil zone of semi-humid deciduous broad-leaved forest in warm temperate zone to the black loessial soil zone of semi-arid grassland in northern warm temperate zone. The northern part of Beishan belongs to the black loessial soil belt, and the southern part of Beishan belongs to the cinnamon soil belt. At the end of 200/kloc-0, the cultivated land area was 407,000 hectares, accounting for 39.9% of the total land area; Garden 1 18500 hectares, accounting for11.6%; Woodland179,800 hectares, accounting for17.6%; Grassland is 22,800 hectares, accounting for 2.2%. The cultivated land reclamation index of Xianyang City is 56.7%, which is much higher than the national and provincial average. The irrigated land area accounts for 48.3% of the total cultivated land area, which is higher than the national average. The effective irrigation area accounts for about one fifth of the whole province, mainly distributed in nanbu county. Generally speaking, the situation of land resources in the city varies greatly from north to south, and the level of economic development gradually declines from south to north. South China has good land conditions, flat terrain, fertile land, high reclamation index and relatively developed agriculture. In the north, the loess plateau is dominated by hills and gullies, and there are also a few mountainous areas. The reclamation index is low, the proportion of forest and animal husbandry land is large, the depth of land resource utilization and the level of agricultural development are low.

Biological resources

Xianyang has a warm climate, moderate rainfall, complex terrain and vast land, which provides good conditions for biological reproduction. Plant resources are abundant. In 200 1 year, there are 50,000 hectares of natural secondary forests in the city, and the dominant tree species are Quercus liaotungensis, Populus davidiana, Betula platyphylla and Pinus tabulaeformis. Robinia pseudoacacia is mainly planted in a large area, and poplar is mainly planted in the surrounding area. The total forest volume is 4.365 million cubic meters. 1 14700 hectares of grassland, and the theoretical carrying capacity is 15700 sheep units. Chinese herbal medicine is rich in resources and has a long history of development and utilization. In 200 1 year, as many as 626 species were found, distributed all over the city. Wild medicinal materials 138 species, 33 kinds of artificial medicinal materials. In addition, wild fruit plants, wild oil plants, fiber plants, spices and chemical raw materials plants all have certain reserves, but their development and utilization are not sufficient. There are more than 40 species of birds 14 orders and 30 families 14 families, and about 40 species of mammals/6 orders14 families. Wild animals with high economic value include raccoons, badgers, ferrets and songbirds.

mineral resources

Twenty-two kinds of mineral resources have been discovered in China, and 10 kinds have been developed and utilized, mainly including coal, iron, limestone, seasonal sandstone, clay, oil shale and petroleum. It is mainly concentrated in the central and northern Tai 'ao area, in which coal resources have the greatest economic value. Coal resources are concentrated in some areas of Binxian, Changwu, Xunyi, Chunhua and Yongshou counties. The proven reserves are1010 billion tons, and it is predicted to be about1500 million tons. The coal types are mainly unbonded coal and long flame coal, which are low metamorphic bituminous coal, with medium ash powder, low sulfur, low to medium phosphorus, low calorific value and high calorific value, and are good power coal and gasification coal. Limestone is an important mineral in Xianyang, second only to coal, with abundant reserves. It is mainly distributed in the northern mountainous areas of Ganxian County, Yongshou County, Liquan County, Chunhua County, Jingyang County and Sanyuan County in the central part, extending 75 kilometers from east to west, with good quality and large thickness, with an estimated reserve of 300 billion cubic meters. The content of calcium carbonate and calcium oxide in the ore is above 97% and 55% respectively. It is a high-quality ore for producing cement, calcium carbide, light calcium carbonate and calcined lime.
