What Different Factors Affect Groundwater Transport?
The groundwater ecosystem is different from various types of ecosystems above the surface. It has a cyclic system of a specific environment and is controlled by natural factors and human activities. Inside it and with the environment, it constantly carries out material exchange and migration, energy conversion and transportation, and information storage and transmission. It is contained in various roles between living and inanimate environments. The groundwater ecosystem is also a link between the biosphere, the atmosphere, and the lithosphere. [1]

Groundwater ecological life composition and its role
- The living components in the groundwater ecosystem are mainly microorganisms (viruses, antigens, chlamydia, bacterial single cells and protozoa), especially bacteria. It includes a variety of bacterial flora, such as heteroaerobic bacteria, aerobic bacteria, aerobic bacteria, anaerobic bacteria, etc., not only rely on photosynthesis, but use the energy of various chemical substances in the earth to maintain its reproduction Grow and form various flora in groundwater. Although these microorganisms are small in size, they play a huge role in the evolution of groundwater. According to research, they are regarded as: converters of matter and energy in groundwater, accelerators and regulators of material circulation, and understanding of the information stored in groundwater. sensor. As modern human activities have and will continue to change the groundwater environment, such as groundwater pollution, excessive mining and the development of other fluids and minerals will affect the natural environment of the groundwater system, causing the ecological balance of water absorption in some areas to be disrupted. In the study of groundwater ecosystems, in addition to the study of natural processes, special attention should be paid to the impact of human activities. [1]
Groundwater ecology
- The excessive exploitation of groundwater causes the groundwater level to drop, which increases the intrusion of surface sewage into the groundwater body. The water cycle of the groundwater system is intensified. The input of man-made environmental substances into the groundwater environment through the atmosphere-soil-surface water system makes the groundwater (especially shallow groundwater) vulnerable to pollution by toxic and harmful substances. The discharge of wastewater and irrigation of sewage caused pollution of groundwater quality. Groundwater over-extraction continues to increase and continues to develop in depth. Pollutants have entered shallow and deep groundwater, causing irreversible damage. As a result, the ecological environment of groundwater is mutated, microbial succession is accelerated, and the connection between the lithosphere, the biosphere and the atmosphere is severed. [1]
