均衡纵剖面是一切水道发育的最终形态，其标准形式是摆线。以实际沟谷与标准摆线间的差异为依据，初步建立了由摆线相关度和沟谷纵剖面几何形态参数两类指标构成的沟谷下蚀趋势评价指标体系，并以鸭儿沟为例进行了实际验证，结果较符合实际。

The equilibrium profile is the ultimate form of all water course. Its standar form is rotation-wheel-line.Based on the difference between actura l gulley and standar rotation-wheel-line,this paper establishes an assessment system that compose of two types of index, the interrelated degree and sha pe parameter of gulley's profile,to calculate the down-erosion trend of gulley.The results show the evaluating results using index system conform to rea lity while taking Yaer gulley as an example to test this system.
