Dasha River in Fengxian County is located in the northwest of Jiangsu Province, at the junction of Jiangsu and Anhui provinces and counties, south of Fengxian County 18km.

Qilu in the north, Beijing-Shanghai trunk line in the east, Beijing-Kowloon Railway in the west, Longhai Line of Eurasia Continental Bridge and Lianhuo Expressway in the south, with superior geographical location and convenient transportation, and close to Xuzhou, Jining, Shangqiu, Bengbu and Huaibei.

Dashahe has fertile land and rich products. 185 1 year, the Yellow River burst its banks for the last time in Panlongji, Anhui Province, which brought great disaster to the people of Fengxian County. After the flood, the wasteland of Dasha River was formed, and the old way of the Yellow River was "the wind blows three feet and the sand buries the loess".

After liberation, the industrious and brave people of Fengxian county built water conservancy projects, planted trees, prevented wind and fixed sand, improved the environment, tried to combine sand prevention and control, combined comprehensive management with economic benefits, and introduced and popularized fruit trees and white crisp pears in the old road of Dasha River basin with orchards as the center.

First, we cooperated with Japan to introduce red Fuji apples, and excavated Dashahe River on the old course of the Yellow River to draw water from the Yangtze River. At present, five pillar industries of grain, fruit, vegetables, animal husbandry and forestry have been formed. Therefore, Fengxian County has been successively rated as an advanced county in sand control, an advanced county in greening, a top ten county in fruit production and a national ecological demonstration zone.

On both sides of the Dasha River, an eco-agricultural area with blue sky and clear water, lush trees, birds and flowers and fruitful results has been formed.

Fengxian County is a "Green Industry Demonstration Zone" determined by China Promotion Association of FAO and named as "National Ecological Demonstration Zone" by State Environmental Protection Administration. Due to the unique natural conditions such as large temperature difference between day and night and long illumination time.

The supply and demand of traditional fruits such as monkey peach, yellow peach, peach and watermelon in China are very active. Dashahe Town was named as "the hometown of red Fuji apples in China" and "the hometown of white crisp pears in China" by the Ministry of Agriculture. .
