Can Tho is a city directly under the Central authorities, located in the centre of the Mekong Delta. Being dubbed as “the capital city of the Southwestern Vietnam” more than one hundred years ago, Can Tho has now become the level-1 city and one of the four provinces and cities of the Mekong River Delta Key Economic Zone–the fourth key economic zone of Vietnam. Can Tho has advantages concerning agriculture and aquatic products, as well as in geographical position that helps the city develop in areas such as urban infrastructure, traffic infrastructure, hi-tech agriculture, agricultural–aquatic products and the seafood processing, tourism and supportive industries. ==Natural Resources== ''Land resource'' There are 2 main groups of land in Can Tho City: alluvial soil and alkaline soil. - Alluvial soil comprises 84% of the area's natural soil, distributed alongside the Ha River and 8–12 km away from the banks. There are 5 types of alluvial soil in this area: riverside fluvisols (comprising 1.9% of the area's soil), gleyic cambic fluvisols (about 58%), cambic fluvisols (about 15.3%), speckled fluvisols (about 4.9%), gley fluvisols (about 4.1%). This rare soil needs to be irrigated and given priority to in planting rice in two to three crops and only a small part of it is used to plant fruit-trees. - Alkali soil comprises 16% of the areas natural soil' There are 3 types of alkali soil in this area : hollow active alkaline soil (comprising about 2.5% of the area's soil), deep active alkaline soil (about 7.0%) and extra deep active alkaline soil (about 6.4%). ''Water resource'' - Surface water: Abundant, lying in the intersection area of the water resource and the tide. The water flow in the high flood period is about 12,800 cubic metres per second. There are also other important canal systems bringing water from Ha River to the West Sea and Ca Mau Peninsula (canals of Cai San, Thot Not, O Mon Thò Doi, Rach Soi - Vam Cong, Xa No); canals in parallel with Ha River (axis of Bon Tong - Mot Ngan) and naturally tide-influenced rivers (Cai Rang River and small tide-influenced canals from Tra Noc to Cai Cui). Those irrigational and hydroelectric works built over the past time have just made the seasonal water flow changed, and not the overall water flow in general. - Underground water: widely distributed. Fresh water is mainly distributed at the water layers of Pleistocene, Pliocene and Miocene Epoches at the depth of 100–300 metres. Some places the water occurs at the depth of only 20–50 metres with rather high quality. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Can Tho City」の詳細全文を読む スポンサード リンク
