摘　　要：针对小流域水土流失的加重,研究提出基于小型水利水保工程对其进行优化设计。通过水利水保工程、经果林、改梯田措施等,改进优化小流域。结果表明,水土流失面积治理程度为88.46%,项目产生的直接经济效益559.85万元,农民人均纯收入增加565元。研究表明,优化后小流域的保水保土能力增强,水土流失得到明显控制,可为安龙县社会经济发展提供生态保障。With the aggravation of soil and water loss in small watershed,the study puts forward the optimization design based on small water conservancy and water conservation projects.This paper studies the improvement and optimization of small watershed by means of water conservancy and water conservation projects,fruit forest and terracing measures.The experimental results show that the control degree of soil erosion area after treatment is 88.46%,the direct economic benefit generated by the project is 5.5585 million yuan,and the per capita net income of farmers is increased by 565 yuan.This shows that the optimized small watershed has enhanced the capacity of water and soil conservation,and the soil and water loss has been obviously controlled,which provides ecological guarantee for the social and economic development of Anlong county.
