Ecological Agriculture Landscape Planning And Design In Dongting Lake Area

With the improvement of people's living standards,the demand for green organic food is increasing year by year.The "three high" production mode of traditional agriculture is easy to lead to agricultural non-point source pollution,soil quality decline,pesticide and fertilizer use increase,air pollution and other problems,which seriously restrict the sustainable development of agriculture and the improvement of food product quality.Ecological agriculture is a way of production to realize the sustainable development of agricultural economy,increase farmers' income,improve product quality and protect environmental resources.Based on the theories of ecology,geography and socioeconomic statistics,this paper summarizes the theoretical connotation,spatial location and development process of ecological agriculture,According to the method of spatial statistics,this paper explores the spatial differentiation characteristics of ecological agriculture in Dongting Lake area,and makes overall planning and layout of ecological agriculture in Dongting Lake area in combination with the existing spatial pattern and the suitability of ecological agriculture,The landscape planning and design of Xinyue village,Lanxi Town,the core area of ecological agriculture,is studied,and the relevant countermeasures and suggestions for the development of ecological agriculture in Dongting Lake area are put forward.The mainresearch conclusions are as follows:(1)The distribution points of ecological agriculture in Dongting Lake area show the characteristics of significant agglomeration,and gradually formed the basic pattern of radiation development around the surrounding towns with Lanxi town in South Dongting Lake area as the core.(2)According to the data of ecological agricultural distribution points,social and economic data and basic land classification,vector and spatial data such as water system,road,slope,slope direction and regional elevation in the site,the suitability of ecological agriculture in Dongting Lake area is comprehensively explored,and the area is planned as "one belt,two axes,three centers and nine areas" according to the suitability results: "one belt" is the ring Dongting Lake area ecological agriculture industrial belt;"two axis" refers to the ecological agriculture landscape axis around the East and west of the lake;"three centers" refers to the core planning area of three cities;"nine areas" refers to nine characteristic ecological agriculture areas.(3)Taking Xinyue village of Lanxi town as an example,the ecological agriculture landscape planning and design were carried out.Based on the design concept,principles and techniques of the relevant excellent cases,combined with the site status and relevant development mode,the landscape design is completed,and the countermeasures and suggestions for the development of ecological agriculture in Dongting Lake area are put forward.
