鲁家街流域属半山丘陵黑黄土区，侵蚀沟发育迅速。据调查分析，地形、土壤是该流域侵蚀沟发育的主要因素。通过对坡长、抗剪强度的力学分析，计算出该流域临界坡长为25m～150m；土体临界高度为4m～5m，为流域综合防治提供了宝贵的资料。鲁家街流域通过对侵蚀沟的治理开发，不仅有效地控制了侵蚀沟的发育，减少了水土流失，而且促进了水土保持产业化和农业的持续发展。
Lushang Street Basin is a hill area of black and yellow soil, rapid development of erosion ditch. According to the survey and analysis, the topography and soil are the main factors for the development of erosion ditch in this basin. Through the mechanical analysis of slope length and shear strength, the critical slope length of the basin is calculated as 25m ~ 150m, and the critical height of soil is 4m ~ 5m, which provides valuable information for the comprehensive prevention and control of the basin. By harnessing the erosion ditch, the Lujiatan Watershed not only effectively controls the development of the erosion ditch and reduces soil erosion, but also promotes the industrialization of water and soil conservation and the sustainable development of agriculture.
