Binh Duong province is located at the edge of contact between the Da Lat eroded elevation zone and the cumulative subsidence zone of the Mekong Delta with two main fault systems dissecting, so the topography is hierarchical in the direction of gradually lower. North to South ( Geography of Binh Duong, Volume 1, National Political Publishing House, 2010 )
In general, the topography of Binh Duong province is typical of the midlands contiguous between the high mountains of South Truong Son and the low plain of the South. The topographic surface has an average elevation of 60 to 40 meters above sea level in the north and a drop of 30 to 10m above sea level in the south. Based on the elevation and morphological characteristics, Binh Duong province can be divided into four main types of terrain: The low hills in Phu Giao district, Bac Tan Uyen district and Tan Uyen town account for about 40% of the total Provinces, flat terrain in all districts, towns and cities account for about 55% of the province’s area, alluvial valley terrain accounts for about 5% of the province’s area and mountainous terrain in the South of Di An town and Dau Tieng district occupy a negligible area.
Nature has created this land many different geomorphologic forms: some areas are eroded, some areas accumulate (due to the deposition of intrusive materials according to the flow), some areas have just been eroded, both accumulation and deposition. Currently, in the whole area, the main activities are washout, erosion. Due to the narrowed forest area and the heavy destruction of the vegetation, the erosion impacts along rivers, streams, and erosion trenches on the surface of the terrain tend to increase, especially in active areas. human economy.
Binh Duong’s land is very diverse and rich in types, which can be divided into the following main groups:
+ Gray land covers an area of about 142,444 ha, accounting for 54.8% of the total land area of the province, distributed mostly in Dau Tieng district, Ben Cat town, Thuan An town, Thu Dau city. One. This soil type is suitable for many crops, especially industrial crops and fruit trees.
+ Red and yellow land is about 65,243 ha, accounting for 25.12% of the total land area of the province, distributed mainly in the districts of Bac Tan Uyen, Phu Giao, Tan Uyen town, Ben Cat town and some places in Dau district. Voice and Di An town. This soil type is suitable for crops of high economic value such as rubber, coffee, pepper, cashew, fruit trees and vegetables ..
+ Alluvial soil covers an area of about 15,725 ha, accounting for 6.05% of the total land area of the province, mainly distributed in alluvial valleys along Sai Gon and Dong Nai rivers. Alluvial soil in Binh Duong is classified as young alluvial with high fertility. Therefore, alluvial soil in Binh Duong is used for growing rice, food, vegetables and fruits, especially the cultivation of high quality, specialty fruit trees.
+ Acid sulphate soil has about 3,300 ha, mainly distributed in areas under Lai Thieu, Thuan An town along Saigon river and areas along Thi Tinh river. This soil is very acidic (pH = 3.5), poor phosphorus. The alum soil, after being improved, can be planted with rice, vegetables and fruit trees, etc.
+ The agglomerate slope land covers an area of about 3,200 ha, distributed in the hydrological forms alternating with red yellow or gray soil, usually in low, flat terrain, between ancient alluvial hills, high concentration in Ben Cat town, Tan Uyen town. The sloping soil is formed by the sedimentation process, so it has a high fertility.
+ The eroded land with pebbles and rocks is only very small, about 91 ha. This group is mainly distributed in Chau Thoi mountain, Tha La, used for quarrying as building materials.
The climate in Binh Duong as well as the climate regime of the Southeast region: hot sun and heavy rain, quite high humidity. It is a tropical monsoon climate that is stable, divided into two distinct seasons: dry season and rainy season.

The Thi Tinh River is a tributary of the Saigon River that originates from Binh Long (Binh Phuoc province), flows through the town of Ben Cat, and then flows into the Saigon River. Together with the Saigon River, Thi Tinh River brings alluvial deposits to the fields in Ben Cat town, Thu Dau Mot city, creating typical orchards.
Be River is over 360 km long, originating from Dak R’Lap stream in Dak Nong province with an altitude of 1000m above sea level. In the downstream part, the section flowing into Binh Duong province is about 80 km long.

Due to the humid tropical climate and fertile soil, forests in ancient Binh Duong were very diverse and rich in species. There are forests instantaneously, immense. The forest in the province has many kinds of precious woods such as: spokes, stars, rosewood, redwood, rosewood … animals, including rare and precious animals. That is also the reason why Binh Duong forest is exhaustedly exploited.
During the 30 years of the war of liberation, especially in the 21 years of the war against the US, bombs and toxic chemicals of the US army destroyed more than 50% of the primeval forests in Binh Duong.
In the 10 years after the liberation day, due to unplanned exploitation, burning forest for cultivation, collecting firewood, coal, forest fire …, the rate of forest cover decreased from 48% to 28%.

In 1997, after separating the province, according to the master plan, Binh Duong had only 18,082 ha of forest land, accounting for 6.71% of the total natural area, of which the forested land was 5,678 ha.
Compared with many provinces in the country, Binh Duong’s minerals are limited in types and types of origin. The most common are minerals of exogenous origin, of which the greatest potential is kaolin and the group of construction materials (sand, pebble, gravel, construction stone, road-paved laterite, brick-tile clay) concentrated. in Bac Tan Uyen district, Tan Uyen town, Thuan An town and Thu Dau Mot city.
Experts have discovered that in Dat Cuoc (Bac Tan Uyen district) there is a large kaolin mine distributed over 1 km 2 with large reserves. The kaolin soil here is considered to be good, can be used in the ceramic industry and as an additive in the production of some industrial products …
