摘要: 拟建大柳树灌区所涉及的省区, 过去以牺牲生态为代价达到粮食自给或自给有余, 然而由于特定的自然条件, 单产低, 粮食生产对全国粮食生产安全贡献率不高, 农业效益低, 农牧民生活不富裕。作者从该区农业气候资源、水资源等特点, 生态环境保护与建设要求以及借"南水北调"引水灌溉的高投入、低产出、高耗资源等状况分析, 揭示了拟建大柳树灌区作为西北甚至全国粮食基地不仅不可能, 而且没有必要。

关键词: 大柳树灌区, 农业气候资源, 水资源, 南水北调, 结构调整

Abstract: The studied regions, which are advised to be developed as the Daliushu Irrigation Area, all have reached food self-support or balance in hand, but they also have cost the ecological environment. In fact, these regions have low unit yield due to the given natural conditions, so have low food production contribution to country, low agricultural benefit,and people in these regions are far from rich. The Daliushu Irrigation Area in planning situates in seriously water-lacking region, the need of water depends on the west line of "Diverting Water from the South to the North Project". The prospect of "high investment but low output" proves that there is no possibility and no necessity to establish Daliushu Irrigation Area and take it as the food base of the Northwest and even China.

Key words: Daliushu irrigation area, agricultural climate resources, water resources, project of diverting water from the south to the north, structure adjustment
