A Comparative Study On Ecological And Traditional Renovation Engineering Design Of Agricultural Land

Cultivated land is the foundation of human survival and development,and land consolidation is an effective way to supplement and protect cultivated land.Different methods of land consolidation will have different impacts on the replenishment of cultivated land,the cost of land consolidation and the natural ecological environment.Under the new situation of national protection of ecological environment,ecological land consolidation has been gradually carried out and paid attention to,but it is still difficult to be popularized.In order to deal with this problem,this paper takes the area of 243.54 hectares in the three administrative villages of Tanxia Town,Xuejia Village,Damiao Village and Dongtou Village as the research object,and analyzes the geographical location,natural conditions,social and economic conditions and land use status of the study area.And carry out on-the-spot investigation,through the comparative study of traditional land consolidation and ecological land consolidation engineering design,put forward reasonable suggestions for ecological land consolidation,so that the ecological land consolidation project can be better implemented.The paper mainly completes the following work:1.Comparison of land leveling engineering design.The design of the ecological land leveling project is compared with the traditional land leveling engineering design in terms of field design,merging of fields,and the construction of ridges.The layout of ecological fields and the construction or shaping of ridges are more scientific and reasonable.Vegetation planting is increased on the slope outside the field ridge,and soil water holding capacity is emphasized.2.Comparison of irrigation and drainage engineering design.The ecological agricultural canal has a trapezoidal cross-sectional structure and ecological brick lining,and the plant growth space is reserved on both sides of the canal top.The cross-sectional view and the rendering of the agricultural canal are compared with the traditional agricultural canal "three-sided light" structure.Ecological agricultural canals have lower economic costs,and are more effective in resisting erosion and siltation,protecting the water environment and preventing farmland pollution.3.Comparison of field road engineering design.In the design of ecological field roads,gravel is used for paving,and plants are planted on both sides of the road for ecological restoration.The material selection and road structure are compared with traditional roads in the form of road sections and renderings.Ecological field roads are more ecologically efficient.4.The characteristic design of ecological land consolidation.According to the general situation of the research area,this paper carries out the characteristic design of ecological fertilizer,biological pools and biological corridors,farmland ecological purification pools and landscapes,improves the farmland ecological environment,lays out the farmland biological survival and escape network,and highlights the new rural construction with rural cultural characteristics.5.Benefit analysis and comparison.The analysis process of remediation benefits respectively expounds the benefits produced by ecological and traditional land consolidation engineering design from three aspects: ecological benefit,social benefit and economic benefit,and conducts a comparative study in terms of benefit.Through the comparative study of ecological and traditional land consolidation engineering design,some characteristic designs of ecological land consolidation are proposed at the same time.On this basis,the huge advantages of ecological land consolidation are fully drawn,so as to better carry out ecological land consolidation,and also provide reference for the ecological design of land consolidation in other areas.
