IV. Preparation Before Construction (I) Organization and Management Work To prepare for the terraced fields, labor, tools, machinery, expenses and other organizations should be arranged in advance whether using artificial or mechanical construction. The construction unit should have a person in charge to participate in order to promptly solve the problems arising during the construction period. The technicians should plan the plots one by one, set the line and check the construction quality. (B) the fixed line method 1, set the baseline method: in the middle of a slope, from top to bottom along the slope and the contour line orthogonal, draw a line, and then based on the slope of the ground and the required width of the field to determine the field Wide corresponding slope length, and take the amount by paragraph, were a number of points,
