东亚和邻近地区受盐影响土壤的性质及盐化危险

Asia is the largest distribution area of salt-affected soils in the world,Very few countries in Asia could escape from hazard of salinization.This paper deals with various salt-affected soils spreading in East Asia and its neighboring regions (including China,Japan,Kampuchea,Democratic Peolpe‘s Republic of Kores,Republic of Korea,Laos,Mongolia,Burma,Thailand and Vietnam),Principles of occurrence of salinization,and features of salt-affected soils in these regions have been studied in the present paper,Based on studies on types,features and distribution patterns of salt-affected soils.a salt-affected soil map of East Asia and its neighboring regions has been complied.Mechanism and manifestation of the salinization hazard on the regional agriculture and ecological environment,measures of preventing salinization hazard and exploiting salt-affected soils in these regions are also discussed.

Features of salt-affected soils and salinization hazard in East Asia and its neighboring regions

Asia is the largest distribution area of salt-affected soils in the world. Very few countries in Asia could escape from hazard of salinization. This paper deals with various salt-affected soils spreading in East Asia and its neighboring regions (including China, Japan, Kampuchea, Democratic People's Republic of Korea, Republic of Korea, Laos, Mongolia, Burma, Thailand and Vietnam). Principles of occurrence of salinization, and features of salt-affected soils in these regions have been studied in the present paper. Based on studies on types, features and distribution patterns of salt-affected soils, a salt-affected soil map of East Asia and its neighboring regions has been complied. Mechanism and manifestation of the salinization hazard on the regional agriculture and ecological environment, measures of preventing salinization hazard and exploiting salt-affected soils in these regions are also discussed.
