摘要
西藏高原自然降水不多，干湿季明显，干旱频率高；近三十多年来气候有变干的趋势；水资源丰富，但利用率很低。干旱缺水是农业生产的主要制约因素；为较大提高农业生产水平，提出了因地制宜开展农田水利建设的建议。
On Tibetan Plateau, the climate is characterized by less natural precipitation with clear seperation of dry and wet seasons. In recent 30 years the climate has been tending to become dry. Although water resources are rich, the utilization rate is low. Drought and shortage of irrigation faciligies are the major factors limiting agricultural production. In order to increase agricultural production level, suggestions on constructing water conservancy facilities suitable to local conditions are proposed in this paper.
