Oncomelania-and-schistosoma-preventing water bank zone revetment structure

Abstract

The invention discloses an oncomelania-and-schistosoma-preventing water bank zone revetment structure. The oncomelania-and-schistosoma-preventing water bank zone revetment structure is characterized in that a herbaceous plant isolation area is arranged below the high water level of a revetment, a soil-fixing erosion-preventing dike dam area is arranged above the high water level of the revetment, and a woody plant oncomelania-expelling area is arranged on one side, far away from water, of the outside of the soil-fixing erosion-preventing dike dam area. Oncomelania-preventing water-tolerant herbaceous plants are planted below the normal water level of the herbaceous plant isolation area, oncomelania-preventing hygrocolous herbaceous plants are planted at the position above the normal water level and below the high water level, and the wide close-planting mode is adopted by all the plants. The soil-fixing erosion-preventing dike dam area is laid with ecological revetment bricks in a building mode, and the width of the soil-fixing erosion-preventing dike dam area is 2-3m. The woody plant oncomelania-expelling area is of a forest belt structure which is composed of hygrocolous trees and hygrocolous shrubs in a mixed mode, and the purpose of tall-and-short matching, the purpose of space combination, the purpose of complementation between the advantages and the disadvantages, and the purpose of oncomelania-expelling symbiosis can be achieved. According to the oncomelania-and-schistosoma-preventing water bank zone revetment structure, perfect combination between water bank zone water conservancy engineering and forestry schistosoma prevention is achieved through thorough engineering design and scientific plant arrangement, and the oncomelania-and-schistosoma-preventing water bank zone revetment structure can play a remarkable role in expelling oncomelania and preventing schistosoma, and can have the advantages of being ecological and attractive, improving the effect, and being multifunctional.

Description

technical field [0001] The invention relates to a snail blood-repelling water-repellent bank slope protection structure, which belongs to the technical field of wetland ecological restoration and urban gardening. Background technique [0002] Schistosomiasis is a major public hazard in the world and is prevalent in more than 70 countries and regions in the world, posing severe challenges to human life, health and safety. The five provinces of Hunan, Hubei, Jiangxi, Anhui, and Jiangsu in the middle and lower reaches of the Yangtze River in my country are the areas where schistosomiasis is most prevalent. More than 95% of the oncomelania area, more than 80% of chronic schistosomiasis patients and more than 90% of acute schistosomiasis patients are distributed in the "three beaches" (river beach, island beach, and lake beach) of the Yangtze River Basin. These areas have the characteristics of dense population, complex environment, large beach area, and high density of snails, ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to propose a slope protection structure for preventing snail blood and water-repelling shoreline from the perspective of improving the ecological environment of the water bank in view of the current situation of wide distribution of beach land, harsh wetland environment and high oncomelania density in schistosomiasis epidemic areas in my country
