(BGO) - Bac Giang is located in the Northeast region of the country, being situated 50 kilometres to the east of Hanoi. It comprises three land forms namely, the lowland or delta land, the midland and the mountainous region.
1. Land resources
Bac Giang province has natural land area of 382,200 hectares with 123,000 hectares for agriculture, 110,000 hectares for forestry, 66,500 hectares for urban, specially used and housing area and 82,700 hectares for other types. Land resources are classified into six groups including:
- Group of golden red soil: about 241, 358 hectares (accounting for 63.13 %), the main group of land with colors of brown-red and golden red depending on soil type, weathering and organic accumulation processes
- Group of alluvial soil: about 50,246 hectares (accounting for 13.14%), mainly distributed around the rivers with rather good nutritional content
- Group of poor soil: about 42,897 hectares (accounting for 11.22%), mainly distributed in such districts as Viet Yen, Tan Yen and Hiep Hoa with low nutritional content which is soft, spongy and able to absorb water easily.
- Group of eroded soil: about 18,809 hectares (accounting for 4.92%) with characteristics of thin layer of soil, lack of fertility which is hard for agricultural cultivation.
- Group of valley soil: about 6,546 hectares (accounting for 1.71%), mainly distributed in small valleys in the middle of mountain ranges, which is formed from washout and deposit making its good fertility.
- Group of golden red sludge soil in the mountains: about 1,008 hectares (accounting for 0.27%), distributed in high mountain ranges close to Yen Tu range and Thai Nguyen province.
2. Water resources
There are three rivers flowing through Bac Giang province called Thuong, Cau and Luc Nam rivers with the total length of 347 kilometers with big discharge and water supply around the year. Water surface, rainwater and groundwater are sufficient for economic sectors and living needs.
- Cau River: the flow through Bac Giang has a length of 101 kilometers with discharge of 4.2 billion cubic meter per year. Irrigation system on Cau river supply for such districts as Tan Yen, Viet Yen, Hiep Hoa and one part of Bac Giang city.
- Luc Nam River: the flow through Bac Giang has a length of 150 kilometers with discharge of 1.86 billion cubic meter per year. In Luc Nam river system, there are more than 170 works mainly lakes and dykes serving as irrigation system for Son Dong, Luc Ngan and Luc Nam districts.
- Thuong River: has a length of 87 kilometer with discharge of 1.46 billion cubic meters per year. Cau Son irrigation system was built on Thuong River to supply for Lang Giang districts and one part of Luc Nam, Yen Dung districts and Bac Giang city.
- Lakes and dykes: Bac Giang has around 70 basins covering an area of nearly 5,000 hectares with some big lakes having big water reserve like Cam Son lake (307 million cubic meters), Suoi Nua lake (6.27 million cubic meters) and Ho Cao lake (1,151 million cubic meters).
- Groundwater resources: groundwater reserve in Bac Giang is estimated at 0.13 billion cubic meter per year with good quality used for living needs and irrigation. However, groundwater is unequally distributed which is mainly in midland areas like Lang Giang, Tan Yen, Hiep Hoa, Viet Yen and Yen Dung districts.
3. Forest resources
Land for forestry in Bac Giang province covers an area of about 146,435.4 hectares including 14.093.3 hectares of specially used forest, 18,879.9 hectares of protective forest and 113,462.2 hectares of production forest. Forests in Bac Giang province play important roles in protection against washout, tube flooding and flash flood, watershed protection and protecting lowlands in the Northern Delta.
Forest resource in Bac Giang province has diversified flora with 276 types of wood, 452 types of herbals with high economic and medical values including bassia, nut tree, canarium, fokienia hodginsii, sindora tree, green ironwood, nyatoh tree, morinda officinalis, ganoderma lucidum. In addition, diversified fauna is a precious genetic resource for scientific and medical study mainly in Yen Tu protected areas including big lorinae, black poliocephalus, pangolin, wolf, tibetan bear, cheetah, leopard, giraffe, wild boar, chamois, big flying squirrel, black &white flying squirrel, langur, golden monkey and turtles.
4. Mineral resources
Some mines of 15 types of natural resources have been found in Bac Giang province with details as follow:
Mineral fuel (coal): in Son Dong, Luc Nam, Yen The and Luc Ngan districts.
Mineral metals: iron ore (in Yen The district), copper ore (in Luc Ngan and Son Dong districts), lead and zinc (in Yen The, Lang Giang and Son Dong districts), gold (Yen The and Luc Nam districts) and mercury (in Luc Nam district).
Industrial minerals: barite (in Tan Yen, Hiep Hoa and Yen The districts), kaolin (in Yen Dung district), peat coal (in Viet Yen and Luc Nam districts), felspat (in Hiep Hoa district).
Construction minerals: clay, brick, tile, sand, boulder, gravel, building stone, anti-fire clay, etc distributed in all districts which is convenient for exploitation and processing to supply for industrial, civil and transportation construction.
