Research On Landscape Construction Of Coastal Saline-alkali Soil Based On Comprehensive Improvement

With the development of economy,the increasing of city population and the shortage of urban land,people gradually recognized the significance of saline and alkaline soil which not only can be used for agricultural land,but also can become a scenic landscape with regional features,especially the importance for city development of coastal area.People,in the past,have already researched and explored saline and alkaline land and achieved certain results in several aspects such as physical,chemical,biological and other aspects.How to carry out the landscape construction of saline and alkaline land in an effective and low-cost way is still a challenge that should be paid attention to in today's society.Through the literature review and field investigation,based on the understanding of the characteristics of saline and alkaline land,learned from the outstanding case of saline and alkaline land landscape construction,this paper considered and discussed the problems on the saline and alkaline land using direction and the exist problems nowadays,summarized the common skills,techniques and forms of saline and alkaline soil,built the foundation for later research and design.According to the theory of salt discharge and the related theory of landscape design,based on the principle with low cost,high efficiency,ecological and wide adaptability,Choose tianjin binhai new area,based on the comprehensive improvement of the coastal saline alkali landscape design research,detailed analyzing the general situation of design area,obstacles of landscape construction.
