Abstract
Water environmental functional zoning is the crucial method to implement the targeted management of environmental factors, which is significant to protect the structure and function of the water ecosystem. Xiaofu River is the main river in Zibo City, which is a typical industrial city in northern China. This paper analyzes the water functional zoning of the Xiaofu River at the provincial and municipal levels. Thereinto, based on the catchment attribute and differentiated management requirement, the functional zone of the mainstream of Xiaofu River is divided into 5 first-level and 14 s-level water functional zones, where the environmental contamination carrying capacity of every functional zone is calculated and checked. It is suggested that the total amount of pollutants discharged into each functional zones should be further controlled and reduced in the future to restore the ecological functions of Xiaofu River.
Highlights
Academic Editor: StefanoEnvironmental functional zoning refers to the spatial and temporal division or classification of environmental elements according to the different functional requirements; it can be regarded as an effective tool for designing and implementing differentiated environmental management policies in various designated regions [1,2]
According to Water Function Zoning of Shandong Province, the first-level functional zone of Xiaofu River is defined as the Xiaofu River Zibo development and utilization area, and the second-level functional zone is divided into Xiaofu River Zibo drinking water source area, Fanyanghe River Zibo drinking water source area, and Xiaofu River Zibo industrial water area
Regionalization divides Xiaofu River Zibo development and utilization area that refers to the river length of 109 km from the river fountainhead to Xiaoqing River estuary into six secondary water function areas, in which one drinking water source area and five agricultural water area are classified
Summary
Environmental functional zoning refers to the spatial and temporal division or classification of environmental elements according to the different functional requirements; it can be regarded as an effective tool for designing and implementing differentiated environmental management policies in various designated regions [1,2]. Environmental functional zoning is supposed to analyze and determine the environmental functions (e.g., drinking water resources, industrial water use, agricultural water use, landscape water use, fishery water) of different regions with the consideration of society, economy and environment, and on the basis of that, the overall planning of environmental spatial zoning management is achieved [7]. The implementation of environmental functional zoning is beneficial for the construction of a regional environmental management framework that is divided into four steps: the first step is data collection and analysis [8], the second is the evaluation
