一我省黑龙港地区总面积35,000余平方公里,除黑龙港河本流域以外,还包括南运河以东大清河以南以及滹沱河、滏阳河之间的一些地区。耕地约占全省总耕地的三分之一,但农业水平较低。本地区年雨量在500mm 左右,年内和年际之间分配极不均匀,年雨量变差系数在0.35—0.4之间。水文地质条件十分复杂,在地下埋藏着一个庞大的咸水体,其储量多达1,539.26亿 M~3,厚度自40—50M 至200—300M 不等。咸水体一般顶板上界
A total area of 35,000 square kilometers in Heilongjiang Province, in addition to the Heilonggang River basin, but also south of the Grand Canal south of the Grand Canal and the Hutuo River, some areas between the Suyang River. Cultivated land accounts for about one-third of the total cultivated land in the province, but the agricultural level is relatively low. The annual rainfall in this region is around 500mm, with extremely uneven distribution between year and year, and the variation coefficient of annual rainfall is between 0.35-0.4. Hydrogeological conditions are very complex, buried in the ground a huge body of salt water, its reserves as much as 153.926 billion M ~ 3, the thickness from 40-50M to 200-300M range. Salt water body roof general upper bound
