黑龙江省治涝区划研究

Study on Waterlogging Control Zoning in Heilongjiang Province

滞涝区划是针对滞涝这一特定对象而进行的地域和区域的划分。区划原则包括:自然条件的相似性;发展方向的相似性;行政区划的完整性;排灌工程布局的合理性等。区划方法首要的是调查研究和资料整理,分析受涝的成因与地形地势、气候特征、土壤性质等。区划研究中最终根据自然地理综合体的相似性和差异性,结合全省河流水系及涝区分布、致涝成因与地理特征等因素,依据区划原则及分析方法,提出了将全省划分为1个一级区、7个三级区,33个四级区的治理区划成果。

Waterlogging control zoning is the region and area divided based on waterlogging control, a special object. Zoning principles include the similarity of natural conditions, similarity of developing direction, completion of administrative zoning and reasonability of drainage and irrigation project layout. Survey, research and data processing is the major method of zoning to analyze the reasons waterlogged and the terrain, climate and soil properties etc,. According to the similarity and difference of natural geography complex, in combination with the water system layout, reasons waterlogged and geographic characteristics in the whole province, based on the zoning principle and analyzing method, zoning study suggested the whole province be zoned one region in grade 1, seven regions in grade 3 and thirty-three regions in grade 4.
