| Abstract: |
| The models of highly efficient use of rainwater and the practical applying patterns in the semiarid areas in Gansu province are analysed in this paper. And the characteristics, theoretical base and practical effects of these models are systematically summarized. Henceafter, the paper suggests focus be paid to the theoritical and technical studies of the biological water-saving techniques, the conventional rainwater resources management techniques, the mulch and no-tillage techniques, and the rainwater fold-enrichment and highly efficient use techniques. |
