| The pasture landscape is an excavation of its landscape value derived from people’s higher demand for natural ecological environment on the basis of grassland animal husbandry function.At present,the research direction of pasturein China is limited to animal husbandry function and ignores its potential landscape value.The research area is concentrated in the northwest and southwest regions,and there are few researches on pasture landscape in the Jianghuai watershed area.The Jianghuai watershed area is rich in grassland resources but the overall utilization rate is low.In order to further explore the application value and landscape effects of pasture landscapes in this area,this paper adopts literature survey research,field investigation analysis,case demonstration and other methods to plan and design pasture resources in this area,aiming to create a new focus of original ecological grassland landscape integrating ornamental,interesting,ecological,educational and productive value in this area.The main research results are summarized as follows:(1)A total of 68 species of pasture plants(herbage and ornamental grass)in 53 genera and 10 families were investigated in the Jianghuai watershed region,covering its ornamental characteristics,optimal ornamental period,ecological habits and so on.The pasture landscape was classified and sorted according to factors such as landscape characteristics,formation mode,utilization mode,plant composition,soil moisture,terrain slope,viewing period and other factors.(2)Statistical data analysis of the topography,hydrology,soil and other characteristics of the Jianghuai watershed area,combined with the advantages of grass resources and comprehensive benefits,and concluded that the development of grassland landscape in this area is reasonable.The comparison and analysis of three different types of grassland in the watershed area of Jianghuai river provides a reference for the landscape construction of grassland.(3)The Jianghuai watershed area is divided into three subregions according to topographic features: low mountain and hilly region,fanchong gentle slope region,and pond low depression region.The site environmental characteristics of each subregion are analyzed,and the pasture landscape construction strategy of each subregion is proposed according to local conditions.In addition,the important nodes of the pasture(entrance,both sides of the road,near the pond,the junction of the forest and grassland,theintersection of the road)were planted to enhance the overall landscape effect.(4)Practical application case—Anhui Jiechen Agricultural Ecology Park pasture landscape planning project has been verified in practice according to the proposed grassland landscape planning strategy. |
