摘要
根据多年实测资料，燕山东段山区正常年份以及丰水年份坡耕地小区坡面径流模数一般为１０００～１５００ｍ３／ｈｍ２，土壤侵蚀模数一般为２５～５０ｔ／ｈｍ２，分别高出荒坡约１０倍和１００倍。为此，研究设计并实施了由水土保持技术、作物增产技术和生态经济沟建设技术组成的坡耕地整治综合技术体系。
According to the measured results of several years,the Eastern Yanshan Mountain Area holds a yearly average runoff modulus of 1 000～1 500m3/ha and ayearly average erosive modulus of 25～50t/ha in sloping field.Based on the local conditions, this study designs and implements a harnessing technical system composed of soil and water conservating techniques, crop production incresing techniques and eco economic gully constructing techniques for small watershed and conducts some successive experiments of major techniques in the system.
