Talking about those things in Xiaoshan-Reclamation (1)

Talk about Xiaoshan, talk about Xiaoshan, talk about people and things in Xiaoshan, and talk about the historical story of Xiaoshan.

At present, everyone in Xiaoshan has the right to speak on reclamation. Reclamation is the wealth of Xiaoshan, the result of a generation's efforts, and a feat to benefit future generations. Now the author asks the older generation about reclamation, and their faces are filled with a kind of pride, which is from the heart and has no cover. According to the time, there are two kinds of reclamation, natural and artificial. For example, the land in Nansha is naturally formed. Because there are many contents of reclamation, the author will explain it several times.

The formation of Nansha

Due to the influence of upstream rivers and tidal currents, the channel of Qiantang River estuary is changeable. In the early Qing Dynasty, Qiantang River was diverted from the north gate. This is the foundation. Because of the diversion of Qiantang River, the original south gate and small and medium-sized gate have been silted up and turned into land, gradually forming a vast Nansha, which means that Nansha is made of natural silt. However, at that time, due to poor governance, dike breaches emerged one after another.

Nansha land formation

After the Qiantang River was diverted from the north gate, the southern sandy land in Haining County was washed by Hong Chao and cut into two parts. The southern sandy land was separated from Haining and was transferred to Xiaoshan in the 18th year of Jiaqing (18 13). At that time, the southern sandy land was silted into a flat land, and the small and medium-sized sandy land was also silted, which was connected with the southern sandy land in Haining. So it starts from Xixing in the west and ends at Sanjiang Gate in the east. The northern boundary is on the south bank of Qiantang River in Zheshan, Hezhuang and Shushan areas, and the southern boundary is in Beihai pond. This vast sand area is collectively called Nansha.

after liberation

Systematically harness Qiantang River, stabilize the river course and take measures to promote siltation, so that the outer edge of Nansha land is silted in a large area, bringing objective cultivated land resources to Xiaoshan, which has a large population and a small population.

The formation of new style

The sediment at the mouth of Qiantang River is silty and rushing. Mainly from Haikou, brought in by tidal bore. In 1950s, Xin 'anjiang Reservoir was completed, which controlled the flood flow to some extent and reduced the upstream flood peak. Later, the Qililong Reservoir was built, which made the river flow stable and created favorable conditions for the formation of new soil.

In the next issue, the author will talk about reclamation projects. Please give me your favorite readers' attention, praise and enthusiastic support. Thank you.
