Research On The Value Of "Li Canal-Gaoyou Irrigation Area" Based On AHP-fuzzy Comprehensive Evaluation Method

This paper mainly studies the value of the water conservancy system of "Li CanalGaoyou Irrigation District"."Li Canal-Gaoyou Irrigation District" water conservancy system mainly includes Gaoyou Lake,Li Canal,Gaoyou Irrigation District,irrigation area of water conservancy facilities,with the development of history,"Li Canal-Gaoyou Irrigation District" has become China’s clever use of rivers and lakes water systems,reasonable regulation of rivers and lakes,water system connection project model,contains rich economic,scientific and other values.In this paper,the construction process of the water conservancy project of "Li Canal-Gaoyou Irrigation District" is sorted out,focusing on water conservancy facilities such as sluice gates and water caves.The irrigation water system of "Li Canal-Gaoyou Irrigation District" takes "lake","river" and "field" as the three-level carrier of irrigation water;"gate","hole","guan" and "dam" as the four channels of irrigation water;and "dry","branch" and "bucket" canal as the irrigation water distribution terminal,so that the Li Canal-Gaoyou Irrigation District forms a dynamic and perfect irrigation water system,and through the study of its irrigation system,the value composition of its heritage is determined.This article consists of three sections as well.Part Ⅰ: Introduction to the first chapter,by introducing the research background,purpose and significance of gaoyou irrigation area,identifying the research area and research subject of this paper,and establishing the research method and research framework of this paper by reviewing the water conservancy system and value correlation research of irrigation heritage.The second part: for the second to fifth chapters,based on hydraulics,on the basis of summarizing the natural environment and social background of the "Li Canal-Gaoyou Irrigation District",the construction process of the "Li Canal-Gaoyou Irrigation District" is sorted out,and on this basis,the "Li Canal-Gaoyou Irrigation District" is interpreted from the whole to the part,and the construction concept of the water conservancy engineering system is interpreted,and the spatial relationship and operation mechanism of the water system in the irrigation area are displayed in illustrated language,so as to determine the value generated by the "Li Canal-Gaoyou Irrigation District".Part Ⅲ: For the sixth chapter,through the above study of the "Li Canal-Gaoyou Irrigation District",the comprehensive value assessment system of the water conservancy engineering heritage is summarized and refined.A value system based on science,economy,ecology and culture,in which the scientific value of water heritage is a key indicator in the evaluation system.Through the establishment of the evaluation system,it provides scientific evaluation standards for the evaluation of future water conservancy engineering heritage and reduces the interference of subjective factors.The value of "Li Canal-Gaoyou Irrigation District" is evaluated through the evaluation model,and according to the assessment calculation results,it provides a reference value for the protection of water conservancy heritage in Gaoyou area in the later period,and provides a reference basis for the study of the value of water conservancy heritage in other regions.Figure[forty one] table[Twenty-nine] reference[sixty one]...
