松嫩平原沙地资源开发与农业发展研究

STUDY ON EXPLOITATION OF SANDY LAND RESOURCE AND AGRICULTURAL DEVELOPMENT IN SONGNEN PLAIN

松嫩平原沙地具有较为优越的自然条件，开发潜力巨大。沙地合理开发的关键是采用沙地生态工程技术、沙地农业工程技术和沙地水利工程技术相结合，建立高效稳定的沙地人工生态系统对沙地进行综合开发。

The sandy land resource in Songnen Plain is one kind of important reserve land resources. Comparing to other sandy land in China, its exploiting conditions are relatively better through decades management. The sandy land exploitation has been put on the order of the day with the westward movement of the focal point of agricultural development in Songnen Plain. According to the relationships between the history of sandy land reclamation and the changes of the sandy land desertification, and the current problems in sandy land utilization, the key of sandy land exploitation is to build a high beneficial and stable man controlled eco system, which not only conforms to the desertification laws but also could meet the demand of human economic development. The study shows that very obvious economic, social and ecological benefits have been obtained through comprehensive exploitation of sandy land using sandy land ecological engineering techniques, sandy land agricultural engineering techniques and sandyland irrigation techniques. These techniques are worthy of spreading.
