Soil-Water Comprehensive Treatment Theory of Urban Fringe

Urban fringe is an active expanding belt, the environment of the urban fringe is complex and frangible. Previous studies have focused on the landscape spatial pattern changes, the spatial-temporal variability of soil pollutants and the land management and policy issues, etc., but it is lack of the theory and practice study of land & water comprehensive remediation in urban fringe areas. This article is taking the Shichuan River as an example. And establish a new concept of comprehensive remediation with soil purification as the key, and with water treatment as the link, meanwhile it will keep clear water with pure land. Form land organic rearrangement theory for different types of land utilization.
