中文摘要水土保持措施适宜性是实施水土保持工程的基础依据。根据对实施四川紫色土丘陵区陡坡荒地典型水土保持措施区,即自然封禁或自然封禁+等高种植林草、坡改梯农耕种植和对照区即未封禁处理水土流失的多年(1983 ~2001年)监测,结果表明: 1.单位降雨因子ER(降雨动能*降雨量)下水土流失模数的变异系数较单位降雨因子R(降雨量)的小而最能反映研究因素对水土流失的影响;2.自然封禁较未封禁和农耕种植具有最显著的水土保持效果而且稳定;3.三种典型的水土保持措施中,自然封禁是目前该区荒坡地最适宜的水土保持措施。
英文摘要The adaptability of soil and water conservation measure is the basic aspect that reflects the effectiveness of soil and water conservation practices. The results, based on the field plot observation of soil and water loss under typical control alternatives, i.e. enclosure, enclosure + contour plantation of trees and grasses and terrace farming,and contrast treatments i.e. un-enclosure and farming on barren land in hilly area of Nanbu, Sichuan basin for period of 1983~2001, showed that:1) The soil and water loss modulus of per unit rainfall factors ER(rainfall kinetic energy*rainfall) is better to reveal the effect features of the studied impact factors on soil and water loss, because the variation coefficient of soil and water loss modulus of per unit rainfall factors ER is smaller than that of per unit rainfall factor R(rainfall); 2) The soil and water control efficiency of enclosure treatment is the highest and stable among the enclosure, un-enclosure and farming treatments; 3) Among the three typical control measures of soil and water loss, enclosure is the best adaptable conservation measure in the studied area, according to the analysis of soil and water control efficiency, potential possible inputs of capital and labors.
