Study On River Landscape Design Based On Improvement Technology Of Coastal Saline Soil

Saline soil is an important land resource,which is widely distributed in the north and south part of Chinese land.The construction and expansion of the city continued to take up a lot of land,and the urban space occupied by saline soil caused a great waste of land resources.The harsh ecological environment not only destroyed the ecological pattern of the area,but also caused the lower grain production and few cultivated land.The development and utilization of saline-alkali land is of great significance to the improvement of the ecological environment,the development of the city and the food security of the country.Saline is not only a valuable potential cultivated land resources,but also has the potential for the development of green space,which can bring the environmental benefits and social benefits.Based on the study of the characteristics of rivers in the coastal saline-alkali areas,this paper explores the landscape design strategies of the rivers in the coastal saline-alkali areas to realize the comprehensive utilization of the saline-alkali soils,creating the diversified value by combining the salinity-alkali improvement technology with the landscape design.In this paper,the related concepts of saline-alkali soil,the improvement of saline-alkali soil and the progress of research are introduced.The theory of urban river landscape and the analysis of coastal landscape characteristics are expounded.The theoretical basis of the combination of salt-alkali improvement technology and river landscape design is elaborated.This paper explored the potential,the principle,the form and function of the construction system of their combination,and then from five angles of ecological restoration,sustainability,improved facilities,construction costs and popular science education system,several landscape design strategies are proposed.By analyzing of domestic and foreign cases,the theoretical part of the previous text can be refreshed.This paper analyses and summarizes the salinity soil improvement technology,and discusses the combination methods of saline-alkali soil improvement techniques and landscape design,which gains some valuable research conclusions.1.Comprehensively and systematically summarizing the reasons,distribution characteristics and the existential form of saline soil,as well as the basic situation of saline-alkaline soil management.2.Classifing and summarizing the combination aspects of saline soil improvement technology and river landscape design from the perspective of landscape design.3.Summing up the general strategies of combining salinity soil improvement technology with river landscape design.
