Study on the Construction Plan of Countryside Type Ecological Belt Based on Ecological Orientation:Taking the Ecological Restoration of Ecological Belt of Chunzi River in Longgang... by TANG Yawen, LIU Xuepeng, HUANG Yilong, YU Yuanyan, LUO yao

“…Ecological belt,is the innovative practice of ecological civilization in Guangdong province,the idea and interpretation of happy rivers and lakes,and the product of water management to a certain stage.In order to explore the methods and approaches of ecological restoration in the construction of ecological belt,taking the ecological belt of Chunzi River in Longgang District,Shenzhen as an example,this paper investigates and monitors the water environment and water ecology of Chunzi River in detail by means of field investigation and experimental analysis,and proposes systematically the water ecological restoration scheme in ecological belt construction according to the theory of focal species.The results indicate that:①Through analyzing the structure and diversity indices of aquatic organisms,the water bodies are in a moderate to heavy pollution state,and higher aquatic organisms are dominated by exotic fishes.The aquatic ecosystem is severely damaged;while the terrestrial ecosystem is less disturbed.②The sewage treatment plant (with effluent water quality reaching the ready class III) — integrated constructed wetland-reservoir water quality purification system,the habitat improvement system of optimized forest structure in mountain-waterfront-shallow,and the symbiotic stable ecosystem of “submerged plants-floating-leaved plants-emergent plants-zooplankton-fish” are put forward,and a water ecology pattern of conservation-recreation-protection is built.③In the future,combined with the implementation of the project,continuous monitoring of water environment and water ecology will be carried out,and restoration scheme will be optimized and improved,so as to provide Shenzhen sample for the construction of ecological belt in Guangdong Province.…”

Data-Driven Model for the Prediction of Total Dissolved Gas: Robust Artificial Intelligence Approach by Mohamed Khalid AlOmar, Mohammed Majeed Hameed, Nadhir Al-Ansari, Mohammed Abdulhakim AlSaadi

“…Saturated total dissolved gas (TDG) is recently considered as a serious issue in the environmental engineering field since it stands behind the reasons for increasing the mortality rates of fish and aquatic organisms. The accurate and more reliable prediction of TDG has a very significant role in preserving the diversity of aquatic organisms and reducing the phenomenon of fish deaths. …”

Research Progress on Landscape Pattern and Its Impacts on Water Environment and Water Ecology of Rivers and Lakes by FANG Shenguang, JIANG Peixuan

“…Landscape pattern makes great influence on the water environment and water ecology of rivers and lakes.In recent years,it is a hot research direction for ecological assessment and restoration of rivers and lakes to reflect the environment and ecological process of rivers and lakes through analysis and research of the landscape pattern at different scales.Meanwhile,the rapid development of 3S technology provides a broad platform for the research and application of landscape pattern,making the analysis of landscape pattern under multi-space-time and multi-scale simpler and more effective.This paper summarizes the research progress of current landscape pattern,reviews its impact on hydrological process,water quality,aquatic organisms and riparian zone,expounds the research methods and results for recent years,further summarizes the similar scientific research achievements by taking the Pearl River Basin as an example for reference,and finally proposes the research prospects.…”

New Vertical-Seam Type Double-Pond Fishway Design and Hydraulic Characteristics Analysis by XIE Meiling, FU Chenghua, WU Yijie

“…Fishway is an important channel to ensure the survival and reproduction of fish and enable migratory aquatic organisms to pass through obstacles such as dams and sluices.A new vertical-seam type double-pond fishway is designed,and the RNG κ-ε model is used to numerically simulate the fishway and calculate its hydraulic characteristics for analysis.The results show that the fishway has three mainstream areas and multiple stable recirculation areas with low flow velocity,and the indoor water flow of the fishway pond has rich flow velocity information,which can provide upstream information for different fish to help them migrate.In addition,the turbulent kinetic energy of the recirculation areas in the rest pond is small and stable along the course,and the maximum turbulent kinetic energy of the stilling basin is.As a new type of fishway,the vertical-seam type double-pond fishway can easily meet the migratory conditions of fish in terms of its hydraulic characteristics,and the relevant results can provide a reference for the engineering design of the fishway.…”

Response of equilibrium states to spatial environmental heterogeneity in advective systems by Roger M. Nisbet, Kurt E. Anderson, Edward McCauley, Mark A. Lewis

“…We present theory that describes this relationship for populations in media with strong unidirectional flow (e.g., aquatic organisms in streams and rivers). Typically, equilibrium populations change in very different ways in response to changes in demographic versus dispersal rates and to changes over local versus larger spatial scales. …”
