Title: Water Resource Monitoring at the Tuojiang Three Emperors Temple Site

Introduction

The Tuojiang River, known for its scenic beauty and cultural significance, is an essential water body in the region. The river serves as a lifeline for the local communities, providing them with irrigation water, transportation, and recreational opportunities. However, with the rapid development of industry and agriculture, the water quality of the Tuojiang River has been deteriorating due to pollution from various sources. To address this issue, the Chinese government has implemented various measures to protect the river's ecology and ensure its sustainable use. One such measure is the installation of water monitoring stations throughout the river basin to collect data on water quality parameters. This paper will focus on the water resource monitoring activities conducted at the Tuojiang Three Emperors Temple site, which is located along the banks of the Tuojiang River.

Background

The Tuojiang River, also known as the Dongting Lake, flows through nine provinces and municipalities in southern China. It is one of the country's largest freshwater rivers and has a total length of 2469 km. The Tuojiang River basin covers an area of about 170,000 square kilometers and is home to more than 35 million people. The river is an important source of hydropower generation and supports a diverse range of aquatic ecosystems.

The Three Emperors Temple site is a historical and cultural relic located on the banks of the Tuojiang River. Built during the Ming Dynasty (1368-1644), the temple was dedicated to the three legendary emperors who are said to have lived in the area thousands of years ago. The temple complex consists of several buildings, including a main hall, an incense pavilion, an ancestral hall, and a bridge. It is an important cultural landmark in the region and attracts numerous tourists every year.

Water Resource Monitoring Activities

The water resource monitoring activities at the Tuojiang Three Emperors Temple site were initiated in 2018 by the local environmental department in collaboration with the Chinese Academy of Sciences (CAS). The purpose of these activities was to assess the water quality of the Tuojiang River at the site and identify any potential threats to both the river's ecology and the cultural relics within the temple complex.

The following water quality parameters were monitored during the monitoring activities: pH值， temperature, dissolved oxygen (DO), ammonia-N (AN), turbidity, and total suspended solids (TSS). Data was collected using manual sampling techniques and analyzed using a portable water quality analyzer. The analysis revealed that the water quality of the Tuojiang River at the Three Emperors Temple site was generally satisfactory, but there were some areas where water quality had deteriorated over time.

Chlorine Levels

One of the most significant concerns identified during the monitoring activities was the high levels of chlorine in the water near the temple complex. Chlorine is commonly used as a disinfectant in public water supplies and can be harmful to aquatic organisms if present in excess. High levels of chlorine can cause fish kills, disrupt ecological balance, and pose a risk to human health.

To address this issue, local authorities have taken steps to reduce the amount of chlorine used in irrigation and other water treatment processes. Additionally, they have implemented educational programs for farmers and residents to raise awareness about the harmful effects of excessive chlorine and promote alternative treatment methods.

Ecological Impacts

The monitoring activities also revealed that certain areas of the Tuojiang River near the Three Emperors Temple site were experiencing negative ecological impacts due to human activities such as agricultural runoff, urbanization, and industrial discharge. These impacts included eutrophication (alkaline conditions that can harm aquatic life), loss of aquatic biodiversity, and degradation of riverbank habitats.

To mitigate these impacts, local authorities have adopted a series of conservation measures. This includes establishing nature reserves and parks along the riverbanks, promoting sustainable agriculture practices, enforcing regulations on industrial emissions, and encouraging public participation in environmental protection efforts.

Conclusion

Water resource monitoring at the Tuojiang Three Emperors Temple site has provided valuable insights into the state of the river's ecology and helped to identify potential threats to both the cultural heritage site and its surrounding environment. By addressing issues such as excessive chlorine levels and ecological impacts, local authorities are taking proactive steps to protect both the Tuojiang River and its cultural significance for future generations.
