Characteristics and surrounding environment of Mohe River in Jimo

The average annual precipitation in Mohe River Basin is about 680mm, and the rainfall is concentrated from July to September, accounting for about 75% of the annual precipitation. The upper reaches are sandy loam, and the middle and lower reaches are loam. There is a steep slope upstream of this river. Tuanbiaozhuang to Guanzhuang, the slope is 6.7‰, and the river course changes more than 200 meters. The river bed gradient near Nanguan is 1.5km, with a gradient of 2‰. Because the river is steep and tortuous, the water potential is fast and the riverbed changes greatly. Before 1702 (forty-one year of Emperor Kangxi of Qing Dynasty), the river reached this "Moqiao" and turned north, then merged into Longquan River along Datong Street and Le Kang Street. At that time, people called this section of the north-south river "near Xihe River", and today the north-south river east of Zhuangtou Village is called "Far Xihe River". During the flood of 1703, the dike burst and the flood went west, forming the embryonic form of today's river channel. From then on, "the river flows straight to the west and no longer flows around the north." The nearby Xihe River gradually silted up and a new channel gradually formed. In accordance with the unified arrangements of the district party committee and government, we will focus on the implementation of the "three major projects" for the regulation of the Ink River, namely, the closed regulation project, the supporting construction project of the pipe network and the ecological regulation project, so as to make every effort to ensure the improvement of the water quality and surrounding environment of the Ink River and realize sustainable and benign development. Shut down the rectification project. Small and medium-sized enterprises are concentrated in the upper reaches of Hongzi River and Aimin River, tributaries of Moshui River. Chengyang Environmental Protection Sub-bureau made use of the favorable conditions of the national pollution source survey, focused on checking the pollution discharge of enterprises, and shut down a number of enterprises according to the pollution discharge. Supporting construction project of pipe network. For areas without supporting pipe network, plan as soon as possible, arrange funds as soon as possible, build supporting pipe network, and connect sewage to Chengyang sewage treatment plant. Last year, * * * built an 8-kilometer sewage branch pipe network. This year, it is planned to build 2 kilometers, which has been completed. Ecological management project. Restore and rebuild the ecological environment of the river basin, improve the self-purification ability of water body, realize greening and beautification on both sides of the Moshui River, harden dams on both sides of the river, plant trees on both sides of the river, not only prevent and fix sand, control dust, but also strive to improve the self-purification ability of water body. In order to prevent the generation of new pollution sources, Chengyang Environmental Protection Branch will implement strict environmental access policies. Resolutely control new projects with high resource consumption and heavy environmental pollution; Strengthen environmental law enforcement and severely investigate and deal with environmental violations; Resolutely close the enterprises that are still not up to standard within a time limit.
