| 摘 要： | 通过对砒砂岩区治理水土流失的生物措施及工程措施进行调研,本文对最适合砒砂岩区生长的油松、沙棘、柠条的特点进行了详细的调查分析,给出砒砂岩区植被建设的几点建议.提出了砒砂岩区综合治理的总体思路,并总结了不同类型砒砂岩区的措施空间配置模式.生物措施方面以沙棘作为砒砂岩区生物措施治理的突破口,在立地条件较好的地方栽种油松、柠条,在造林方式上宜采用混交造林;在工程措施方面要结合沙棘植物"柔性坝"技术,以大、中型拦泥库为骨架,以淤地坝为主体,建设支流坝系.实现淤粗排细,改善进入下游河道的水沙条件及泥沙组成.

| Abstract: | By inveresting measures for soil erosion in soft rock area,this paper makes a detailed analysis on such most suitable plants as chinese pine,seabuckthorn and ningtiao,gives some advices and general ideas on vegetation construction and comprehensive treatment in these areas also,this paper sums up the spatial allocation patterns of measures on different types soft rock areas.For biology measures,seabuckthorn is the breakthrough,chinese pine,ningtiao can be planted on places with good site condition.Mixed forestation is the most suitable forestation structure.For engineering measures,we should consider seabuckthorn vegetation "flexible dam" technology,take large and medium-sized dams as its framework,silt dams as it principal part,contruct branch dam system,in order to deposit coarse silt and exclude fine silt,and reform the run off and sediment condition and sediment composition in lower reaches of the yellow river. |
