July's Jiuquan, summer trees are luxuriantly green. Mu from Dunhuang City Water Saving Demonstration Garden to the large ecological water urn County Demonstration Garden, the Gobi Desert from the Suzhou area of green vegetables to grow Guazhou County once a barren land covered with Brilliant red agate-like Chinese wolfberry, are to demonstrate the vitality in recent years to the development of efficient water-saving agriculture in Jiuquan City, the fruitful results. Jiuquan City, said Yao-Water Affairs Bureau, the city of JiuquanCheck Valves in total 2.774 billion cubic meters of water, of which 2.4 billion cubic meters of agricultural irrigation water, industrial and urban domestic water use 213 million cubic meters, 161 million cubic meters of ecological water . As the scale of water use is close to the utilization of water resources, water resources have been difficult to meet the rapid development of Jiuquan City, the economic and social needs of increasingly serious contradiction between supply and demand of water; same time, the ecological water use accounts for only 4.6% of total water resources, resulting in vegetation decline and desertification and other ecological problems, and severe environmental deterioration. Jiuquan city vice mayor in charge of agriculture, said Wang Xicheng, Jiuquan to achieve sustainable economic and social development and protecting the environment, must be saving the top of their agenda, and accelerate the construction of water-saving society, inhibit the excessive growth of water consumption from explore the potential of Butterfly Valves limited water resources, improve water use efficiency, ease the contradiction between water supply and demand. Deteriorating ecological environment has on the water levels in Jiuquan City, a deeper understanding of Jiuquan City, the preparation of the 100 acres of agricultural water conservation planning, introduction of "Building on the implementation of water-saving society" and "The development of efficient section of Jiuquan City water, agriculture calls for the views of peasants to increase income, "clearly the work of the city's basic agricultural water-saving ideas, goals and tasks, security measures, and will include the annual task of government responsibility for assessing the book. Municipal government is not comfortable in the local financial situation, only the water of a municipal financial arrangements for funding on a year over five million yuan. To guide the farmers to develop efficient water-saving features of agriculture, the Government means to build demonstration park to show the development of peasant agriculture and the benefits of efficient water-saving features. Since 2007, Jiuquan City, has in Dunhuang, Suzhou, water urn, etc. to build demonstration zone (point) 43. Currently, Jiuquan City in grapes, hops, greenhouse, flowers, seed-based high-performance characteristics of agricultural acreage reached 140 million mu, of which 9.8 million mu of field, more than 5,000 yuan to 18.8 million mu efficient field development, the development of high field above 2000 yuan to 112 million mu, the annual water volume of 50 million cubic meters. Reporter in the town of Dunhuang Mo Gao seen contiguous grapes, jujube, and Globe Valves greenhouse, the plants lush, growing well, a set of efficient water-saving irrigation technology demonstration, ecological and environmental protection, tourism and leisure as one of the modern and efficient water-saving agricultural demonstration garden has taken shape. Dunhuang city, said Mayor Ma Shilin, 2008, the Dunhuang mu efficient water-saving irrigation demonstration garden at home in Mo Town, Gan Su warburg a group and start home warburg six groups, has completed the 2319 acres of grape micro-irrigation, micro- irrigation jujube 899 acres, 331 acres of greenhouse vegetables, drip irrigation, drip irrigation for growing cotton, 1336 acres. Mu farmland and water park only 330 cubic meters, less than one half of field crops, and annual income of 1.8 million yuan, is 20 times the income of wheat. Park is China's agricultural water and rural water supply and Technology Association, the provincial Water Resources Department were designated as "high efficiency water-saving agricultural technology demonstration Park (Dunhuang)" and "Dunhuang efficient water-saving demonstration" to promote national and provincial. To Plug Valves conserve limited groundwater resources, maximize the use of surface water, Jiuquan City, the support of the project, actively seek state support, speed up construction of water projects, have implemented a medium-sized Irrigation District, water efficiency model, the final stage transformation of water canal project to make good rate of irrigation works and irrigation water use efficiency improved. Currently, Jiuquan City, the completion of large and medium water saving reform for irrigation area of 14, accounting for 65% of the total irrigation area, to improve the irrigation area of 38.5 mu. "EleventhBalance Valves Five-Year Plan" period, Jiuquan City, the completion of water project construction total investment of 350 million yuan, nearly 1,000 km converted various channels, canal building more than 2,230 seats, improving the irrigation area of 90 mu, the new water-saving irrigation project area of 30 mu, the city's comprehensive agricultural irrigation quota per mu in 2005 to 506 cubic meters by the decline to the current 486 cubic meters of irrigation water use coefficient of 0.531, alone, in water more than 30 million cubic meters.

译文：拧紧阀门酒泉发展高效节水型特色农业纪实
7月的酒泉，夏木葱茏。从敦煌市的万亩高效节水示范园区到金塔县的万亩生态节水示范园区，从肃州区戈壁滩上长出的绿油油的蔬菜到瓜州县曾经的不毛之地上挂满的一颗颗红玛瑙似的枸杞，都以勃勃生机向人们展示着近年来酒泉市发展高效节水农业的丰硕成果。酒泉市水务局局长李耀介绍说，酒泉全市年用水总量为27.74亿立方米，其中闸阀农业灌溉用水量24亿立方米，工业和城市生活用水量 2.13亿立方米，生态用水1.61亿立方米。由于水资源利用规模十分接近水资源可利用量，水资源已难以满足酒泉市经济社会快速发展的需要，供需水矛盾日益突出；同时，生态用水仅占水资源总量的4.6%，致使植被萎缩、土地沙化等生态问题日益严重，生态环境不断恶化。截止阀酒泉市主管农业的副市长王喜成说，要实现酒泉经济社会的可持续发展和保护生态环境，必须把节水摆上重要日程，加快建设节水型社会，抑制用水量的过快增长，从有限的水资源中挖掘潜力，提高水资源利用效率，缓解水资源供需矛盾。日益恶化的生态环境使酒泉市上下对节水有了更深刻的认识，酒泉市编制了百万亩农业节水规划，出台《关于全面建设节水型社会的实施意见》和《酒泉市发展高效节水型特色农业促进农民增收的意见》，明确了全市农业节水工作的基本思路、目标任务、保障措施，并将年度任务列入政府责任书进行考核。市委、市政府在地方财政并不宽裕的情况下，仅节水一项，市级财政每年安排资金就达500万元。为引导农民发展高效节水特色农业，政府采取建设示范园区的方式，向农民展示发展高效节水特色止回阀农业的好处。2007年以来，酒泉市先后在敦煌、肃州、金塔等地建成节水示范园区(点)43个。目前，酒泉市以葡萄、酒花、日光温室、花卉制种为主的高效特色农业的种植面积达到140万亩，其中，万元安全阀田达到9.8万亩，5000元以上高效田发展到18.8万亩，2000元以上高效田发展到112万亩，年节水量达5000万立方米。记者在敦煌市莫高镇看到，连片的葡萄、大枣和日光温室里，农作物郁郁葱葱，长势良好，一个集高效节水灌溉技术示范、生态环境保护、观光休闲为一体的现代高效节水农业示范园已初具规模。敦煌市市长马世林介绍说，2008年，敦煌市万亩高效节水灌溉示范园在莫高镇甘家堡村一组和苏家堡村六组启动，目前已完成微灌葡萄2319亩，微灌大枣899亩，温室瓜菜滴灌331亩，大田棉花滴灌1336亩。园区内蝶阀每亩农田年用水量只有330立方米左右，不到大田作物的二分之一，而且年收入都在1.8万元以上，是种植小麦收入的20倍。园区被中国农业节水和农村供水技术协会、省水利厅分别定为“农业高效节水新技术示范园(敦煌)”和“敦煌高效节水示范点”，向全国和全省推广。为节约有限的地下水资源，最大限度地利用地表水，酒泉市以项目作支撑，积极争取国家扶持，加快节水工程建设，相继实施了大中型灌区节水改造、节水增效示范、末级渠系改造等节水项目，使灌区工程完好率和灌溉水的利用率不断提高。目前，酒泉市完成节水改造的大中型灌区达到14个，占灌区总数的65%，改善灌溉面积38.5万亩。“十一五”期间，酒泉市累计完成节水工程建设投入近 3.5亿元，改建各类渠道近1000公里、渠系柱塞阀建筑物2230多座，改善灌溉面积90万亩，新增工程节水灌溉面积30万亩，全市农业亩均综合灌溉定额由 2005年的506立方米下降到目前的486立方米，农业灌溉水利用系数达到0.531，仅此一项，年节水超过3000万立方米。
