景泰川灌区,位于我省北部的景泰县境内,是我省大型电力提灌工程之一。工程设计流量10.56秒立米,有效灌溉面积30.42万亩。本区属于干旱型的大陆性气候,风沙多,年平均降水量仅186毫米。上水前土地大面积荒芜,除洪水漫地和旱砂田外,泉水灌溉面积仅有6600亩。由于受干旱风沙自然灾害的影响,生产水平低下。景电工程建成后,彻底改变了本区的干旱面貌。现在灌区已建成数十个林荫蔽道的集体、国营农场,粮食产量比上水前增长一倍多。从1976年起,全县开始扭转长期吃国家回销粮的局面,人民生活有了很大的改善,并提供较多的商品粮。
Jingtai River irrigation area, located in the northern part of Jingtai County in our province, is one of the province’s large-scale power irrigation projects. 10.56 seconds engineering design flow meters, the effective irrigation area of 304200 acres. The area belongs to the arid type of continental climate, with more sand and dust, with an average annual rainfall of only 186 mm. Before the water a large area of barren land, in addition to flooding and dry sand fields, spring irrigation area of only 6600 acres. Due to the natural disasters caused by the arid sandstorm, the production level is low. After the completion of the Jingdian Project, the droughts in this area have been completely changed. Now that the irrigated area has built dozens of sheltered collective and state-run farms, its grain output more than doubled before that of Sheung Shui. Since 1976, the county has begun to reverse the long-term situation of eating back national food. The people’s life has been greatly improved and more food commodities have been provided.
