The so-called three fields,i.e., horizontal terraced field,field with sand cover and deposited

建国40年来,甘肃省的陇东、陇中、陇南和洮岷山区的干部群众,始终不渝地坚持进行了“三田”(即水平梯田、砂田、沟坝地)建设。特别是农村实行联产承包责任制以后,省委、省政府把兴修“三田” 作为发展旱作农业的基础工作来抓,并及时制定了符合农村实际的组织管理办法和具体政策,使全省的“三田” 建设进入了扎扎实实稳步发展的新阶段。1985年以来,平均每年兴修“三田”62万亩,从1987年起突破80万亩;按山区人口计算,人均达到1亩。随着配套措施的逐步落实和管理水平的不断提高,“三田”的增产效益愈来愈显著,人们对“ 三田” 建设在旱作农业生产中的地位和作用的认识愈来愈深刻,兴修“三田”的积极性也愈来愈高。

On the basis of orientutive observation made of the soil and water loss on 3 plots(terracedfield, Chinese fir plantation and bare spot), and the analysis of surface runoff water quality and soilcharacteristics, it is believed that building terraced field and planting trees on the sloping tillage fieldscan decrease not only the quantity of water and soil loss, but also the loss of nutrient matter from soil.The modulus of soil erosion on the horizontal terraced field and Chinese fir plantation are 2. 4%...

On the basis of orientutive observation made of the soil and water loss on 3 plots(terracedfield, Chinese fir plantation and bare spot), and the analysis of surface runoff water quality and soilcharacteristics, it is believed that building terraced field and planting trees on the sloping tillage fieldscan decrease not only the quantity of water and soil loss, but also the loss of nutrient matter from soil.The modulus of soil erosion on the horizontal terraced field and Chinese fir plantation are 2. 4% and4. 01% of bare plot. The index of surface run off on the former two sites will decrease by 57. 7% and67. 7% than that on the bsre plot. The loss of N. P. K and organic matter on the horizontal terracedfield is 67. 26%, 70. 4 %, 66. 4 % and 95. 57% lower than that on the bsre plot. and also the loss ofN. P. K and organic matter on Chinese fir plantation is 72. 07 %, 77. 02%, 43. 18% and 90. 7%lower than that on the bsre plot. Moreover, the time of surf see runoff on the horizontal terraced fieldand Chinese fir plantation is held up by 30 min as compared with bare plot. and the flowing quantityon the floodpeak will decrease 2 to 3 times.

通过对试验区水平梯田、杉木林和裸地三种不同处理地段水土流失状况的定位观测,以及地表迳流水水质和土壤理化性状的分析,认为水平梯田和茂密的林木覆被地表,不仅大大减低土壤侵蚀量,而且能降低土壤营养物质的流失量。据研究,水平梯田和杉木林区的年土壤侵蚀模数分别力荒坡对照区的2.4%和4.01%,年地表迳流系数分别为对照区的42.3%和32.3%;梯田区氮、磷、钾和有机物质的流失量分别比对照区低67.26%,70.49%,66.4%和95.57%;杉木林区分别比对照区低72.07%,77.02%,43.18%和90.7%;此外,水平梯田和杉木林地对滞洪和减洪、增加土壤入渗方面也有重要作用,其产流时同比对照区迟30-50min,洪峰流量减低2-3倍。
