摘要
针对胶东农业灌区引黄调水工程中导致的区域性水土流失问题,提出胶东农业灌区引黄调水工程水土保持质量评估方法,为相关部门制定水土保持整改措施提供科学依据。由于水土保持与水土流失之间具有显著相关性,因此从这两方面分析工程所涉及区域水土保持现状。基于水土流失、水土保持与土壤质量间的紧密相关性,以土壤质量描述水土保持质量,构建水土保持质量评估模型;依照不同评估指标权重与隶属度确定胶东农业灌区内不同区域土壤质量指标分值,得到水土保持质量评估结果。结果表明,工程涉及区域中滨州市和烟台市水土保持质量处于偏低水平,潍坊市水土保持质量处于中等偏下水平,并针对水土保持质量较低的现状提出水土保持质量提升策略。
Aiming at the regional soil and water loss problems caused by the water diversion project from the Yellow River in Jiaodong agricultural irrigation area,the evaluation method of soil and water conservation quality of the water diversion project from the Yellow River in Jiaodong agricultural irrigation area was put forward,which provided scientific basis for the relevant departments to formulate soil and water conservation rectification measures.Due to the significant relativity between soil and water conservation and soil ero⁃sion,the current situation of soil and water conservation in the area involved in the project was analyzed from these two aspects.Based on the close correlation among soil erosion,soil and water conservation and soil quality,the soil and water conservation quality was de⁃scribed by soil quality,and the evaluation model of soil and water conservation quality was constructed.According to different evalua⁃tion index weights and membership degrees,the soil quality index scores of different regions in Jiaodong agricultural irrigation area were determined,and the evaluation results of soil and water conservation quality were obtained.The results showed that the quality of soil and water conservation in Binzhou city and Yantai city were at a low level,and the quality of soil and water conservation in Wei⁃fang city was at a lower middle level,and according to the current situation of low quality of soil and water conservation,this study put forward some strategies to improve the quality of soil and water conservation.
