This dataset covers the sustainable development evaluation data of the East Daxu Flood Storage and Detention Zone in the Chaohu Lake Basin, focusing on the ecological function, economic resources and flood control subsystems, with a total of 18 specific indicators measured.
The economic resources subsystem includes the output value of economic crops, energy consumption of 10,000 yuan GDP, breeding efficiency, electricity consumption of 10,000 yuan GDP, and the value of recreational tourism, which are used to assess the output capacity of the regional economic activities and the efficiency of resource utilization, respectively.
The flood control subsystem includes the value of loss per acre of conventional cash crops, the cost of transferring people, the value of loss per acre of farmed water area, the cost of house repair, the level of flood storage and the volume of flood storage, mainly reflecting the impacts of flood hazards on the regional economy and society as well as the capacity of flood control.
The ecological function subsystem measured the climate regulation value, water purification value, air purification value, soil retention value, carbon fixation value, biodiversity value, and scientific research and education value to quantify the role of the flood storage area in ecosystem services and sustainable development. The dataset includes data from two development scenarios, namely, the current development level scenario for Dongda Wei, and the predicted scenario based on the current development level after ecologically transforming the farmland and increasing the area of wetlands in the area.
This dataset can be used as a reference for the coordinated development of the flood storage area.
This dataset covers the coordinated development evaluation data of the East Daxu Flood Storage and Detention Zone in the Chaohu Lake Basin, focusing on the data of the ecological function, economic resources and flood control subsystems.
The data of the ecological function subsystem are derived by accounting the value of ecological service functions such as climate regulation, water purification, air purification, soil conservation, carbon fixation, biodiversity and scientific research and education, etc., and a variety of accounting methods such as the alternative cost method, the result parameter method and the shadow engineering method are adopted.
The data for the economic resources subsystem and the flood control subsystem are derived from the Anhui Provincial Statistical Yearbook-2021 and the Circular on the Issuance of Matters Relating to the Scope of Compensation Scope, Compensation Objects and Compensation Standards for the Utilization of Storage and Stagnant Flood Zones in 2020, covering key indicators such as the value of loss per unit area and energy consumption of 10,000 yuan GDP.
The dataset includes scenarios of the current development level of Dongda Wei, as well as forecast scenarios made on the basis of the current development level after the ecological transformation of farmland and the increase of the wetland area in the area, in order to assess the sustainability of the different development modes.
(1) Data integration: Integration of data from different sources to form a unified database.
(2) Accounting for the value of ecological functions: Value the data of ecological function subsystems and quantify the value of ecological service functions such as climate regulation, water purification and air purification by adopting mature economic appraisal methods such as the alternative cost method and the outcome parameter method.
First, the reliability of the data sources is fully guaranteed. The data of the ecological function subsystem are based on validated value accounting methods, such as the alternative cost method and the shadow engineering method, which are widely used in the assessment of the value of ecological services, ensuring the authority of the data. The data of the economic resources subsystem and the flood control subsystem are derived from statistical yearbooks and relevant policy documents released by the government, which further ensures the accuracy and authority of the data. Secondly, the dataset covers multiple aspects of the flood storage area, involving the main indicators of the ecological, economic and flood control subsystems, ensuring the completeness of the data.
