一、发展过程延边朝鲜族自治州位于吉林省东部,北与黑龙江省接壤,东与苏联毗邻,东南与朝鲜民主主义人民共和国相望。面积42700m~2,属山林地区,河网较密,水能资源丰沛。本区气候特点是冬季漫长寒冷,夏季短暂温暖,冬夏气温相差悬殊,夏季最高气温35℃,冬季最低气温则达-40℃左右,稳定封冻期长达3个月。长期以来水文站作为基层单位,采取分兵把口、定点观测的组织形式和测验方式,不利于多快好省地收集水文资料。位于长白山麓的二道白河水文站,为了解决白河地区水电建设对水文资料的急需,于1967
First, the development process Yanbian Korean Autonomous Prefecture is located in the eastern part of Jilin Province, bordering Heilongjiang Province to the north, the east and the Soviet Union adjacent to the southeast and the Democratic People’s Republic of Korea. An area of 42700m ~ 2, is a mountain area, dense river network, abundant water resources. The climate in this area is characterized by long and cold winter, short summer summertime, and great difference between winter and summer temperatures. The highest temperature in summer is 35 ℃ and the lowest temperature in winter is about -40 ℃. The stable freezing period lasts for 3 months. For a long time, the Hydrological Station, as a grass-roots unit, has taken measures to divide the troops into exits, set up fixed-point observations and test methods, which is not conducive to the collection of hydrological data more quickly and economically. Erdaobaihe Hydrological Station at the foot of Changbai Mountain, in order to solve the urgent need of hydrological data for hydropower construction in the Baihe area, in 1967
