Topography: Dong Nai is located in the region connecting to Di Linh highland and the Mekong River Delta. Its terrain is gradually low from the north to the south, with three regions: low hill terrain, at an altitude of 200-800m, accounts for 8% of the natural area; alluvial ground terrain, at altitude of 20-200m, accounts for 80% of the natural area; wavy delta terrain, at an alti tude of 20m, account for 12% of the natural area. Generally, Dong Nai terrain is relatively flat, its soil structure has good compressibility (over 2 kg/cm2), facilitating to industrial development investment and project construction with low cost.


Natural area: 5,894km2.


Climate: Dong Nai is in the monsoon tropical region with temperate climate, few floods, storms and disasters, the average annual temperature is 25-260 C. There are two main seasons. The rain season is from May to October, the dry season lasts from November to April of the following year.

Land: According to FAO/UNESCO classification, Dong Nai has 10 soil groups:

Alluvial soil: 27,929 hectares accounting for 4.76% of the natural area, centrally distributing in delta zone near the Dong Nai river in districts of Nhôn Trach, Long Thanh and Vinh Cuu.

Waterlogged soil (grey): 26,758 hectares in area account for 4,56% of the physical area, mainly distributing in delta near the Dong Nai River and in mountainous valleys being flooded in the rain season. The land is appropriate for cultivating water rice and short-term plants in the dry season.

Black soil:  131,604 hectares accounting for 22.43% of natural area, centrally distributing in Tan Phu, Dinh Quan, Xuan Loc, and Cam My districts. It has high humus and protein content and can be used for developing fruit trees with high economic values.

Grey land: 234,867 ha making up 40.04% of the natural area and are distributed in districts of Vinh Cuu, Long Thanh and Nhon Trach. If transformed, the land may be used to grow many kinds of crop-plants.

Reddish land: The land, a 95,389-hectare area, makes up 16.26% natural area and is distributed in districts of Thong Nhat, Trang Bom, Xuan Loc, Cam Ly and Dinh Quan. The rather fertile land is suitable to grow industrial plants.


There are also another land groups making up a small proportion of natural area such as sandy soil with 613 hectares (making up 0.1%), eroded land with 3,180 hectares (0.54%), eruptive stone formed land with 2,422 hectares (0.41%), brown land with 11,377 hectares (1.94%) distributed in Xuan Loc district, which are not suitable to develop crop-plants because of being not fertile, the infertile alluvium soil takes up 139 ha(0,02%). Generally, Dong Nai has vast land with highfertility, the black soil and basalt oil areas are large that are suitable for the development of industrial trees, fruit trees, and processing industry.



Natural resources:

Water: Dong Nai has an abundant surface water resource for life and production because of many rivers and spring, an average density of 0.5-1.2km/km2. The rivers of Dong Nai and La Nga alone are 220km and 70km in length respectively. Apart from supplying water, the Dong Nai river is an important waterway in the province.

Underground water resource, which may be exploited to serve industrial production, is not much. The area which may be most exploited are gathered around south Long Thanh and north Bien Hoa. Exploited capacity can reach over 10,000 cubic meters a day.


Hot mineral water was discovered in 5 places in which Nho Spring has its capacity of 10,000 cubic meters a day.


Forest resources and multi-biology:  Floristic composition in Dong Nai belongs to damp forests in a tropical region with monsoon and heavy rain, so the plant – animal system here is a wide variety of species. Dong Nai forest have specific families of bamboo, chestnut, “castor – oil plant”, insuti, malabar, almond trees. A survey showed that there were 614 species of plants from 390 lines, 110 families from 70 groups in 6 different plant branches. There are 252 species of animals in which beasts have 61 species, birds 120 species, reptile 54 species, amphibian 12 species, especially the South Cat Tien forest has many species of precious and rare animals such as rhinoceros, Benteng oxen, Catoong deer, tigers, squirrels, peacock.


Dong Nai has an abundant forestry resource with a 178, 216-hectare area making up 30.38% of the province’s natural forest in which natural forests are 110,117 hectares, and planted forests are 44,757 hectares, which makes it easy to develop tourism and exploit forests economically.
