一、凤翔灌区基本情况 凤翔灌区始建于1956年,位于黑龙江省萝北县境内,是鹤岗市辖区内最大的一处自流灌区,灌区内含东明朝鲜族乡的10个村屯,乡政府驻地在灌区内。灌区设计总面积3.35万亩,设计净灌面积 3万亩,现实灌溉面积仅为2.4万亩。灌区有两个渠首,从两个流域的河流引水,一是烟筒山渠首,从松花江的一级支流嘟噜河引水,该渠首始建于日伪时期,拦河坝由原来的插柳坝发展到现在的堆石坝,且年久失修,水毁严重,每年都要投入大量的人力、物力进行维修,设计灌溉面积2.7万亩,实际只能达到2万亩;二是鸭蛋河渠首,从黑龙江一级支流鸭蛋河引水,设计灌溉能力1.5万亩,实灌面积为4 000亩。灌区内斗渠以上各级用水渠道45条,总长139公里,各类构筑物223座。 I. Basic Conditions of Fengxiang Irrigation District Fengxiang Irrigation District was founded in 1956 and is located in Luobei County, Heilongjiang Province. It is the largest gravity irrigation area in Hegang City. The irrigation area contains 10 village and township governments of Dongming Korean ethnic group Resident in the irrigation district. Irrigation area design a total area of ​​33500 acres, the design of irrigation area 30000 mus, the actual irrigation area is only 24000 mus. There are two canals in the irrigated area, which draw water from the rivers in the two river basins. The first is the chimney mountain canal, which leads from the Tudur River, a first tributary of the Songhua River. The canal was first built during the Puppet Period. Development to the present rockfill dam, and a long time disrepair, serious water damage, each year to invest a lot of manpower and material resources for maintenance, design irrigated area of ​​2.7 hectares, the actual can only reach 20,000 mu; From the first tributary of Heilongjiang Duck River water diversion, design irrigation capacity of 15,000 mu, real irrigation area of ​​4,000 acres. There are 45 water supply channels at all levels above the bucket quarries in the irrigated area, with a total length of 139 km and 223 types of structures.
