Study Of The Ecological Slope Protection Technology Of Ganfu Plain Irrigation Area

Through continuous continued construction of ancillary facility and water savingreconstruction project for more than ten years in Ganfu Plain irrigated area,we haveaccumulated rich experience in the aspect of channel regulation.As the guiding ideology,such as water ecological civilization is put forward, we start trying to change thetraditional slope protection methods and set out to research and application of someecological slope protection technology in the irrigation area, to realize the goal ofmodern irrigation area and ecological irrigation district.Combined with learning forreference and experimental analysis method, choose different channels as a pilot, Basedon the vegetation investigation results of engineering area, Select the appropriate plantsuit for growing on the channel slope and the fact of the project to carry on the designfor construction. Based on test monitoring of some of the structure, function andeconomic indicators, According to a set of evaluation index standard analysis made onthe test data, Finally uses the analytic hierarchy process (ahp), fuzzy comprehensiveevaluation model of comprehensive evaluation of various ecological slope protection,conclude the design and construction technology of relatively good project effectecological slope protection.The main work and achievements are as follows：(1)By studying various ecological slope protection design principle, materialcomponents, technical service and the way of vegetation, etc, to master the structure andfunction of ecological slope protection system.(2)Through the test, to monitor the structure of the ecological slope protectionindex, function index and economic index. Structural indicators include: unit weight，capillary porosity, organic matter content, stable permeability, content of nutrientelements, vegetation coverage, vegetation barren-resistant and vegetation droughtresistance performance, etc.; Function indicators including sediment erosion, averagepull-out force per unit area of plant, landscape coordination and landscape aestheticsdegree,etc.; Economic indicators including the cost per unit area and the difficulty ofmaintenance degree, etc.(3)Combined with the characteristics of irrigated area, chose different functionarea as pilot regions, to design and construct ecological slope protection.(4)Though analyzing the above indicators, to give a comprehensive analysis of theadvantages and disadvantages of all kinds of ecological slope protection, based on thecharacteristics of irrigation channels of Ganfu Plain irrigation area, we can arrive at aconclusion for the design and construction of ecological revetment technology ofirrigation channels in this area.
