| Abstract: | 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. |
