应用小气候学理论和旱作技术原理，对陕西关中、陕北不同气候区旱作农业中隔坡梯田工程体系进行了分析研究，计算出坡地集水面积与梯田面积的比例：半干旱偏旱区为１１～１８∶１，半干旱区和半湿润偏旱区为８～１１∶１（一熟区为２～３∶１），半湿润区为３～４∶１（洛川为１∶１）；梯田地埂高度：坡度３°～５°坡地，取１ｍ～２ｍ高的地埂高度，５°～１０°内取２．５ｍ～３．０ｍ高度，１０°～１５°内取３．５ｍ埂高，此为旱作区集水农业的发展提供科学依据。
Based on the theory of microclimate and the technical principle of dry farming, this paper analyzes and studies the agricultural terrace system in drought-affected areas in Guanzhong and northern Shaanxi, and calculates the ratio of water-harvesting area to terrace area in semi-arid and semi-arid area Is 11-18: 1, the semi-arid and semi-humid dry areas are 8-11: 1 (the first-crop area is 2-3: 1), the semi-humid area is 3-4: 1 ); Terrace 埂 height: slope 3 ° ~ 5 ° slope, take 1m ~ 2m high ground 埂 height, 5 ° ~ 10 ° take 2.5m ~ 3.0m height, 10 ° ~ 15 ° take 3. 5m 埂 high, which provides a scientific basis for the development of catchment agriculture in arid area.
