滦河流域水文、地质与经济概况分析

摘要

The annual average temperature of the Luanhe River Basin gradually decreases from south to north, and the temperature change is -1.4℃ ～ 10.6℃. For many years, the average rainfall over there is 519.2mm. catchment area reaches 44750km2, and river length is 888km. The Luanhe River Basin belongs to Inner Mongolia northeast on its axis of China and Korea platform north margin and parageosyncline area of Mount Yanshan in tectonics, which is the standard Albis-style fold structure. Taking 2007 as the benchmark year statistics, GDP in that area is 365.647 billion yuan, accounting for 1.48% of the whole country. Real GDP per capita is 27,200 yuan, which is 1.46 times as much as the national average.%滦河流域年平均气温由南向北逐渐降低,温度变化在-1.4℃~10.6℃。流域多年平均降水量519.2mm。流域面积44750km2,河长888km。滦河流域在大地构造上属于中朝陆台北缘的内蒙地轴东北部及燕山准地槽区,属标准的阿尔比斯式褶皱构造。以2007年为基准年统计滦河流域,地区生产总值3656.47亿元,占全国的1.48%。人均GDP2.72万元,是全国平均水平的1.46倍。
