| 摘 要： | 本文以土地详查、淤地坝普查成果为基本依据，结合典型调查，研究分析了河龙区间南片水土保持各项措施的保存率，认为在空间尺度上，分行政区给出的保存率较为真实的反映了社会环境、自然环境因素的相对作用程度及其主导关系，且有实际应用意义，据此文中进一步核实评述了该区水保措施的保存面积、措施结构及质量等。该区水保措施的状况在黄河中游干旱半干旱地区具有广泛的代表性，分析结果可作为水沙分析、水保规划、土地资源与环境评价等工作的重要参考依据。

| Abstract: | The study is based on fruits of detailed soil survey, gelleral check dam survey, and typical investigation. We have analysised remain percentages and present conditions of various water and soil conservation measures in the southern Hekou-Longmen district,and conclude that social fector is prominent in erosion scale, the provided remain percentages of water and soil conservation measuresdivided by administrative area ha7,e practical value. Accordingly, this study has checked and evaluated remain area, stfructure and quality of water and soil conservation measures in the area. The conditions of water and soil conservation measures in the area is typical in the drought and semi-drought middle reaehes of the Yellow River, the conclusion can be considered as important reference to water -sand analysis, water and soil conservation planning, land resource and environment evaluation. and so on. |
