| The concept of “ecological slope protection” is the extension of “sustainable development concept” and “sponge city” in the field of ecological water conservancy construction,as a new interdisciplinary discipline,it is intended to solve the contradiction between the construction of river slope protection and ecological environment,and to seek a balance point.“Ecological slope protection”as the future development of China's river slope protection direction,domestic in theory and practice level are in the initial development and application stage,in order to scientifically and rationally evaluate and select the quality and effect of ecological slope protection and the structure of ecological slope protection,this article based on relevant evaluation theory,evaluation principles and evaluation methods,construction of the evaluation system and the evaluation model form and the quality of the effect of ecological slope protection structures,so as to provide efficient means and technical support for the design and construction of ecological slope protection construction and acceptance and evaluation.(1)Theoretical study on the existing domestic and international ecological slope protection,combined with the development of the concept of the sponge City,the combination of the two arguments,analysis of innovative summarizes the relevant theoretical concepts,connotation,mechanism and design principle of ecological slope protection,etc.Research on the current situation of ecological slope protection evaluation at home and abroad were analyzed and summarized.(2)According to the different materials used in slope protection,the classification of traditional slope protection and ecological slope protection system is systematically summarized,and from the design concept,the external form,the main function of a number of angles of the two systems are compared and analyzed.(3)Evaluation and assessment methods related theoretical principles were summarized analysis and comparison,the comprehensive evaluation system is put forward and the measurement and calculation of the evaluation index are discussed,analytic Hierarchy Process empowerment,comprehensive evaluation index and the gray Combination build comprehensive evaluation model,comprehensive evaluation and Analysis on the ecological slope protection structure system.(4)Combined with Xichuan County stork river city section of river slope protectionactual project case,using the established evaluation model for comprehensive evaluation,Through the comparison and selection of the project,select the best and most reasonable ecological slope protection program,comprehensive analysis of the weight of each evaluation index,obtains the leading factor and the key factor,and provides the theoretical basis and technical guidance for the construction of such slope protection project.(5)Finally,through the analysis of actual established case,analyze and compare the differences in the evaluation results of the two evaluation methods and the reasons for the differences,detailed analysis of the differences between the two methods of calculation,and their principles,advantages and disadvantages and scope of application were systematically summarized,while the evaluation system and evaluation model to verify the rationality. |
