The general landform of Youganpu is high in the north and south, and low in the middle. The southern and northern parts are basically mountains and woodlands. The relatively flat areas are concentrated in the central area, which is easy to develop and construct. It is a place where the construction land of Youganpu is concentrated, and the afforestation of mountain forests has created a beautiful environment for the construction of the whole village.
1. Mountains
Youganpu Village is surrounded by mountains, with Eagle Mountain in the east, Tiger Mountain in the south, Opposite Mountain in the west and Shiling Mountain in the north. It is a flat area in the middle, showing the shape of a small basin. Among these four hills, Tiger Mountain, which is 132 meters above sea level, is famous for its shape resembling a crouching tiger. The highest mountain in the village is "Eagle Mouth Mountain", with an altitude of 187 meters. The rest of the mountains are about 1 meters above sea level.
II. Xihe
In ancient times, people in the village called this section of the river that flows through Youganpu the "Golden Hook River". It originates from Yantian Changbiao, crosses Youganpu, flows through Tangli, Zhutang, Tangxia and Qiaotou, flows into Dongjiang, and goes out to sea from the Pearl River Estuary. According to Chen Botao's Dongguan County Records, the water system from Fenggang Yantian to Qiaotou is called Jiujiang Water, later called Shima River. Within the jurisdiction of Youganpu Village, there are two small streams, one is called Zhuzaili and the other is called Hengli, which meet at Gelikou and flow into Jingou River.
In 1964, due to the construction of the Dongjiang-Shenzhen water diversion project, the river flowed backwards. The Jinguou River system, a tributary of Dongjiang River, was renamed Dongshen River to supply water to Hong Kong and Shenzhen. After the reform and opening up, the sewage discharged from the factory was serious. In order to prevent water pollution, the Dongshen water supply system was changed to pipeline water supply, and the original Dongshen river channel became a sewage channel. In 25, the town government began to build sewage drains on both sides of the river to intercept sewage to Zhutang Sewage Treatment Plant. Youganpu, located in the south of the Tropic of Cancer, has a subtropical climate, with hot summer and cool autumn, rainy summer and autumn, typhoons and cold winter and spring.
