The Research Of The Schistosomiasis Epidemic Area Landscape Renovation Planning Based On The Agroforestry Ecosystem

With the expanding of city construction, many of the most inaccessible schistosomiasis epidemic area nowadays have become urban waterfront space, and the management of schistosomiasis is not optimistic in our country at present. Although schistosomiasis epidemic area is shrinking sharply, new affected area is growing. Only a handful of areas meet the spreading block standard in areas that do not meet the control standard. The governance methods of schistosomiasis in the past also has a lot of problems, they often at the cost of the expense of environment and ecological destruction. They only pay attention to immediate effect and lack of long-term, continuous governance mechanism.In this paper, agroforestry ecosystem is the research object, through its ecological characteristics to suppress the only intermediate host snails breeding so as to cut off the spread of schistosomiasis. The elements of the agroforestry ecosystem can also become composition element of urban landscape space at the same time. Through specific landscape transformation, the agroforestry ecosystems can meet the demand of city beautification.This paper uses the methods of literature research, field research, the multidisciplinary comprehensive study and design practice, on the basis of the comprehensive prevention and control of schistosomiasis theory by agroforestry ecosystem at home and abroad, combined with domestic and foreign outstanding landscape cases, according to the planning principles of the schistosomiasis epidemic area landscape renovation based on the agroforestry ecosystem, in the case of zhuzhou yunlong two type society demonstration area, carry out the research of schistosomiasis epidemic area landscape renovation planning based on the agroforestry ecosystem, the specific research results are as follows:(1) Conclusion the epidemic status of the schistosomiasis and the disadvantages of current control techniques, a combination of related research results at home and abroad, combing the ecological prevention and control mechanism of agroforestry ecosystem by changing temperature, illumination system and soil conditions, through the ploughing and intercroption in the system, by the allelopathy effect of plant, through water logging, fish eat and other ecological way combining inhibit the growth of snails.(2) Discuss the feasibility of the introduction of landscape renovation in agroforestry ecosystem, analyzes the general research situation of agroforestry ecosystem and landscape of communion, proposed the agroforestry ecosystem landscape renovation of three steps, namely reforming assessment first, then put forward transformation principle, finally put forward concrete reform methods.(3) Before making specific landscape planning on schistosomiasis epidemic area, the trematode area landscape renovation planning principles is proposed firstly, namely the principle of ecology, landscape and economic principles. The three principles can provide planning ideas and planning guidance for zhuzhou yunlong two types social demonstration area in schistosomiasis epidemic area landscape renovation planning and practice.(4)Combining with the approval of changsha-zhuzhou-xiangtan agglomeration shall set up a national "two type society", comprehensive reform pilot area and yunlong demonstration zone as the key construction of "two type society" as one of the five major demonstration area of policy background under the state council, yunlong demonstration area has the condition to be the laboratories of schistosomiasis epidemic area landscape renovation planning, walk in the forefront of the country. This paper analyzes the general situation of the project, planning background, water system and the status of schistosomiasis of the yunlong demonstration zone, a landscape planning about the overall layout of the yunlong demonstration zone and ecological lake revetment planning were put forward.The research results show that through the agroforestry ecosystem, it can control schistosomiasis scientifically in a long-term, and it can be brought in the city landscape space through reasonable landscape transformation. This is a new voice, represents a trend in the development of landscape diversity, it can provide reference for the development of comprehensive governance landscape and ecological landscape.
