摘　　要：本文从宏观决策出发,提出发展“两环”、整治“两区”,作为黄土高原地区农业建设与综合治理开发的总体构思。“两环”分布在本地区四周平原、盆地及其毗邻的山体,内环为以商品粮生产为主的金色环带,外环为以防护林建设为主的绿色环带;“两区”在本地区中心的丘陵、沙区,东南是以治理水土流失为重点的农牧区,西北是以治理风沙危害为重点的牧业区。“两环”和“两区”的构思,将有助于国家治理开发黄土高原地区制订方针政策,进行建设投资。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.
