The soil properties with the characteristics of higher salinity and lower nutrient status are the problem demanding prompt solution for enlarging the use of saline-alkali soil resources and raising reclamation and cultivation efficiency in the seashore area. The types of saline-alkali soils and their development condi tion have been systematically analysed by using statistic method in terms of the practical cases in this area. The results have been theoretically summarized. The complex resolution to alleviate drought, waterlogging ,salinization of soil and unfertiles oil was worked out.The way to improve and utilize the soil resources was also put forward, which had the scientific value and played a direct guiding role in fully utilizing the wast eland and seabeach resources and promoting economic development in coastal area of China.
