陕西有闻名遐迩的郑国渠、成国渠、三白渠等古代水利工程,且有郑国、庄熊罴、马钧等一批古代治水人物。近代又有著名水利专家李仪祉先生主持兴建的“关中八惠”和“陕南四惠”。新中国成立后,陕西建成的宝鸡峡、交口、石头河等一大批水利骨干工程,对全省政治、经济和人民生活发挥着重要作用并将产生深远影响。从1992年起,陕西连续5年成为全国水利先进省。 然而,总结陕西水利发展史,不难发现这样一个脆弱点,即较为普遍地存在着有河而没有水,有水而没有库,有库而不能蓄,有蓄而不能发电的现象。陕西省河流不少,但一遇天旱,河底朝天,几乎断流,灌区供需矛盾尖锐。由于缺水,灌区社会经济效益得不到充分发挥。特别是近两年特大干旱,仅宝鸡峡灌区因缺水不能播
There are a number of ancient water conservancy projects in Shaanxi, such as Zheng Guantao, Zhuang Xiongtao, Ma Jun and so on. Modern well-known water experts Mr. Li Yizhi presided over the construction of “eight Guanzhong” and “four benefits in southern Shaanxi.” After the founding of New China, a large number of key water conservancy projects including Baojixia, Jiaokou and Shitouhe, which were built in Shaanxi Province, have played an important role in the political, economic and people’s livelihood of the province and will have far-reaching impact. Since 1992, Shaanxi has become the national water conservancy advanced province for five consecutive years. However, to sum up the history of the development of water conservancy in Shaanxi, it is not hard to find such a vulnerable point where there is a widespread phenomenon of rivers and no water, no water and no water, no water and no water, no water and no electricity. Many rivers in Shaanxi Province, but in case of drought, the river overturned, almost cut off, sharp contradiction between supply and demand in irrigation areas. Due to lack of water, the social and economic benefits of irrigated areas can not be fully utilized. Especially in the past two years, the major drought, only irrigation area in Baoji can not be broadcast due to lack of water
