Shuitu Baochi Xuebao, 2002 以黄土丘陵沟壑区内相邻的2条支沟(羊道沟和插财主沟)为研究对象,采用横向平行对比分析途径,研究了小流域水土保持措施的水文效应.结果表明在黄土丘陵沟壑区,水土保持措施能够有效地减少小流域的径流、泥沙模数,消减洪峰流量、降低径流含沙量,滞后洪峰出现时间,缩短洪水历时,改变降水产流、产沙关系,但对降雨量与流域径流、泥沙量之间的相关性没有大的影响.

黄土丘陵沟壑区土地适宜性评价研究—以山西省中阳县圪针耳流域为例
Shuitu Baochi Xuebao, 2003 以黄土丘陵沟壑区的山西省中阳县圪针耳流域为例,提出了黄土丘陵沟壑区土地适宜性评价原则,建立了该区土地适宜性评价的指标体系,筛选出评价主导因子,并将该流域分为177个地块,采用专家打分和权重法对每一地块的适宜性进行了评价,结果为:宜农地总面积为185.3hm2,占流域总面积的19.34%;宜林地总面积为192.4hm2,占20.08%;宜牧地总面积为563.63hm2,占58.83%;其它地总面积为16.67hm2,占1.74%。
