摘　　要：本文根据我们多年多项大田试验的结果,结合试区综合治理的实践,阐述了黄土丘陵沟壑类型区的特点;提出了水土保持农业增产体系设计的原则,并明确了适合这一地区农业增产的配套措施:用多年的实测数据,分析了增产效益及其原因。通过试验区多年的生产实践,证明所提的水土保持农业增产体系,有明显的水土保持效益和较高的增产效果,适合在广大的黄土丘陵沟壑区示范推广。The characteristic of loess hilly and gully region was ex- pounded and the principle of yield increasing system design of soil and water conservation agriculture was proposed based on several years field experiment and the practice of comprehensive control in research area. The sets of measrues of raising crop production which suit to the area was defined.From result,the benefit of yield increasing and its reason were analysised.The many years production practice in rsearcharea prov- ed the proposed yield increasing system of soil and water conservation agriculture had a remarkable benefit of conserving soil and raising yield, which suit to popularizing in the vast loess hilly and gully region.
