中国盐渍土资源现状及改良利用对策
Present Status of Saline Soil Resources and Countermeasures for Improvement and Utilization in China
摘要
Abstract
Soil salinization is one of the major factors leading to deterioration of agroecological environ-ment.Saline soils not only inhibit the growth of crops but also lead to soil degeneration , and even lead to a re-duction of land utilization rate.The soil salinization is due to a variety of factors such as climatic conditions, landform and human activities.The distribution of soil salinization in China was widely with large area and many types.Its total area is about 99.13 million hectare, and accounts for 1.03% of the total land area of China.Saline soils are distributed almost in every province of China but mainly in Northwest, North, North-east and coastal regions.In this paper, the sources of salt, desalting ways, and the area, types and forming causes of saline soil in every province were analyzed, and some basic countermeasures were put forward to im-prove the soil salinization.关键词
