摘要
五华县地处广东省东北部的韩江上游。水土流失面积875.83km^2,占全县总面积27.15%。北部最为严重,东部次之,西北部和中部再次之,西南部比较轻微。水土流失的主要类型有:片状流失、沟状流失和崩岗流失等3类。根据各种水土流失类型组合形式和地理分布特点,以及防治水土流失方向的一致性,将五华县划分为5个水土流失区,并提出了各区的水土流失特点及其治理意见。
Wuhua county, on the upper reaches of the Hanjiang River, is situated at the northeast of Guangdong province. The area of soil-water erosion in the county amounts to 875.83km^2, which takes up 27.15% of the whole territory. According to the degree of the erosion, 4 areas are ranged, from high to low, as follows: the north sector, the east sector, the middle and northwest sectors and southwest sector. Three principal types of the soil-water erosion, the lamelliferous erosion, the trench erosion and landslide erosion, could also be classified. Based on the composition form, the characteristics of geographical distribution and the uniformity in the prevention and harness of soil-water erosion, five subregions are divided and measures are relatively put foreward against to the different situation in each subregion.
