Water is the source of life, and ensuring water security is essential to sustainable development. More than 70% of the earth's surface is covered by the ocean, but the freshwater resources available for human activities are extremely limited. The population growth, industrial and agricultural production activities and the rapid development of urbanization in modern society have had a huge impact on the limited water resources and water environment. In 1993, the United Nations General Assembly made a resolution to determine that March 22 every year is World Water Day, which aims to arouse public awareness of water conservation and strengthen water resources protection. The theme of my country's commemoration of the 2020 World Water Day and China Water Week activities is Insist on water conservation first and build happy rivers and lakes.
On the evening of March 22, 2020, the academic lecture of the Agricultural Situation Lecture Hall hosted by the Association of Science and Technology of the Academy of Agriculture and Technology was held in the QQ group by live broadcast as scheduled. Dean Chen Jing of the School of Agricultural Science and Engineering was invited to give an academic lecture entitled Water System Protection in the Process of Urbanization for all students in the school. The lecture was hosted by Lu Zhiyu, a 19th grade student from the Agricultural Engineering Institute.
Dean Chen Jing used a number of pictures to explain to everyone the problems in the current urbanization development that she discovered in recent years of scientific research: 1. In the process of urbanization advancement and road network construction, the current water system is ignored and the existing water system is destroyed. A large number of them exist; 2. During urbanization, if the construction of small towns does not pay attention to the protection of the water system, rudely destroys the water system and fills the water system, it will form a major problem on the surface, which is hard to return; 3. A large number of rivers, lakes, and wetlands are buried and destroyed The integrity and connectivity of the original water system reduced the water areas and channels for water storage and flood discharge, and destroyed the ecological balance of the original water system.
In the lecture, Dean Chen emphasized to the students the importance and necessity of protecting and respecting the existing water system as much as possible. She emphasized that the current river system is the result of long-term elimination and optimization by nature. The environment and ecology of the current river system are stable and balanced to a certain degree. She also pointed out that the river system is an important part of the flood control and security system and must be based on the best The idea of protecting and respecting the existing water system can find a balance between breaking and standing.
Therefore, she proposed that “while meeting the needs of flood prevention and security, we respect and protect the current water system to the utmost extent; dig large and fill small, large straight and small bend, and bend as you go. In addition, road network planning and town master plans must be repeatedly communicated with water conservancy departments; water conservancy departments must also strengthen top-level design.
In the more than one-hour lecture, Dean Chen Jing explained the importance of water conservancy development and urban construction in a simple and simple way, which inspired the teachers and students participating in this lecture to think about the development of water conservancy and agriculture, and encouraged the students to learn well. Professional knowledge. In the online Q&A session of the lecture, students enthusiastically asked questions, and Dean Chen also answered them one by one.
Every inch of land has a breath, every drop of water has past and present lives, treat them kindly! The appeal is the resonance of all water conservators, and the heart and purpose of every water conservator. The children of water will also hold on to this original intention and strive to move forward!
Dean Chen Jing is a doctoral supervisor of our college. He has been engaged in agricultural water resources management research for a long time. The main research directions are agricultural water management, rural water management systems and mechanisms, theoretical research on water resources management and allocation, river basin water resources management and agriculture Research on resources and environment.
After the lecture, a knowledge contest with World Water Day, China Water Week, Water Conservation Priority as the main content was held. The topics of the contest included Dean Chen's research on water system protection, Chinese rivers and domestic water issues in this lecture. Related management systems, students actively participate in answering questions!
