From the macroscopic decision it is advanced that developing "tworinged belts" and to renovate "two regions" should be the general concep-tion for agricultural construction and comprehensive dredging and explo-ration of the loess plateau. The two circles distribute on plain
basinand adjacent mountain of the area
the inner circles is a golden range
mainly producing commercial grain
the outer one is a green one withthe construction of shelter-forest. The two regions are hill and sandarea in central part of the area
the southeast part is for farming andbreeding taking soil and water conservation as the major work
and thenorthwest for breeding taking control of sand and wind harm as stress.The conception would help the country to map out policy and strategyand to investing for the dredge and exploration of the loess plateau.
