在调查分析流域现状的基础上，根据坝系相对稳定理论，按坝系相对稳定条件和标准，采用坝系相对稳定系数（坝地面积与坝控集流面积之比）1／20，暴雨洪水频率2％，对全流域进行坝系规划，使坝系形成后达到相对稳定，以实现对流域洪水泥沙的长期控制，并对规划结果作了经济评价。评价结果表明，该项规划在经济上是合理的，生态效益及社会效益也很大。
Based on the investigation and analysis of the current status of basins, according to the relative stability theory of dam system, according to the relative stability conditions and standards of dam system, the relative stability coefficient of dam system (dam area to dam flow area ratio) 1/20, storm flood The frequency is 2%. The dam system is planned for the whole basin to achieve a relatively stable dam formation. In order to achieve long-term control of flood and sediment in the river basin, an economic evaluation of the planning results is made. The evaluation results show that the plan is economically reasonable and has great ecological and social benefits.
