一、概况平山县位于河北省石家庄市西北部,太行山东麓,总面积2648km2,总人口46万,是个俗称“八山一水一分田”的山区县。由于受地形地貌、近代战火、滥采滥伐等自然、人为活动影响,在上个世纪中后期水土流失面积达1286.45km2。由于严重的水土流失,造成了岗南、黄壁庄水库淤积2.6亿m3,调洪蓄水能力降低,安全度汛压力巨大,水质日益恶化;
First, an overview Pingshan County, located in the northwestern part of Shijiazhuang City, Hebei Province, the eastern foot of the Taihang Mountains, with a total area of 2648km2, the total population of 460,000, is commonly known as the “eight mountains and one water a field” mountain counties. Due to natural and man-made activities caused by topography, modern warfare, excessive deforestation and so on, the area of soil erosion in the middle and late of the last century reached 1286.45km2. Due to the serious soil erosion, the deposition of 260 million m3 of Gangnan and Huangbizhuang reservoirs has resulted in the reduction of flood control and water storage capacity, the huge pressure of flood season and the deteriorating water quality.
