| Today,the domestic farm ecological construction,to meet the market demand,commercial capital to enter the field of agriculture,the number of ecological farm is also more and more,the development trend of agricultural production presents scaleintensive,planning and design of ecological farm becomes more and more important.The ecological farm is different from the city park and wetland,and the farm pays more attention to the production of organic agricultural products without destroying the original ecological environment.The ecological benefit,enhance the farm construction of economic and social benefits,the author analyzes the development process,the development of ecological agriculture mode,the existing problems,that the construction of key ecological farm to achieve the combination of planting and breeding,recycling;the attractive service state;the landscape function promotion,the service of agricultural production;comply with the national policy,to solve the contradiction in land use.Based on these factors,the ecological model of planting and breeding cycle was constructed,and the ecological farm was planned and designed.The main results are as follows:(1)this paper sums up a series of problems on the development of domestic and foreign countries and case models: farm construction,the pursuit of economic benefits,and neglect of ecological construction.The scale of intensive production planting,planting industry and breeding industry lead to separation,create a farm plant landscape only ornamental value,cannot meet the needs of agricultural production;planning and design of the farm mostly rely on decision makers,lack of scientific guidance of the scientific methods;not real problems such as using the zero discharge of sewage and waste of resources.(2)according to the theory of planting and breeding cycle,we use the theories and methods of agricultural ecology,landscape ecology and landscape planning and design to build an ecological breeding cycle model.Model construction is mainly divided into planting unit,breeding unit,sewage disposal unit,digestion unit and intelligent monitoring unit.Planting unit: zoning,planting production,ecological purification and economic landscape plants such as hybrid Pennisetum,aloes,teak,the full service of agricultural plants.The planning and construction of breeding units are as follows: the construction of farms includes ecological farms,considering the reduction of construction land,the development of barren hills,and innovative design of high bed farms for construction on slopes.Road planning in the site is divided into clean road and dirt road,which plays a role of epidemic prevention and environmental protection.Sewage discharge is divided into rain and sewage,according to the vertical site,so that rain and sewage separation.The planning and construction of the clean sewage digestion unit,combined with the comprehensive planning of the sewage sludge,constructed wetlands,biomass coke and sewage ecological ditches,so as to achieve "zero discharge" of the sewage".Through planning and construction of earthworms breeding sheds,mature ponds,waste digestion and utilization of resources.The ecological agriculture production model of planting and breeding cycle was constructed by comprehensive planning of breeding,planting,digestion and purification.(3)the principle of the guiding ideology and construction follow farm construction,integration of landscape tour function construction,the breeding cycle of ecological model as a guide,planting unit,breeding unit,decontamination unit,digestion unit and intelligent monitoring unit into site planning,planning and design of the Shanwei City Lufeng source ecological farm. |
