摘要
针对黄河下游典型滩区最近几十年的土地利用变化进行分析,发现耕地面积变化不大,建设用地呈现明显增加趋势,而未利用地面积明显减少。随着未利用地的大量开发利用以及耕地面积的缓慢增长,黄河下游濮范台滩区的土地利用强度逐步增加,而土地利用类型更加趋于单一。流量6000m^3/s洪水影响的主要土地利用类型是旱地和河渠未利用地;流量8000m^3/s以上洪水对建设用地影响较为明显。
The land use changes of downstream beach area of the lower Yellow River had been analyzed in this research.Cultivated land had an insignificant change while the building land and the unused land had a remarkable decrease.The development of unused land and cultivated land caused the increase intensity and less type of land use.The flow of 6 000 m^3 / s had a marked influence to the dry farmland and the unused land in the canal while the submerged land types were rural settlements and construction land when the discharge was greater than 8 000 m^3 / s.
