Abstract: This paper deals with the development and trend of the rainwater harvesting research in the semiarid regions. Attentions are also paid to the potential and problem existed in the water-harvesting system. The history of water-harvesting study can be divided into three stages: ①Primitive rainfall utilization (before 1950), ②Great progress in basic theory studies and technique developments of the rainwater harvesting system (1950-1980), ③Systematic research of water harvesting techniques (after 1980). Research on rainwater harvesting in China was relatively late. It was started in 1960s, however, the systematic studies was carried out until 1980s. Characterized by simple operation, high adaptation and low cost, rainwater harvesting techniques have a great potential to be used in many aspects, and they would provide the possibilities of setting up new agricultural ecological system and improving ecological environments in the arid and semiarid regions.
