摘要
三江平原是我国重要的商品粮基地,其发展经历了上世纪50年代的大开发和80年代开展的大规模旱田改水田工程,井灌水田比例逐年增加,现已形成了井灌区,井灌、渠灌相结合和雨养农业区的多种灌溉农业发展模式。为了合理开发利用三江平原水土资源,利用模糊识别模型对三江平原的地下水水资源承载力进行评价,同时利用级别特征值对三江平原地下水资源承载力级别进行划分,得到了满意结果。
Sanjiang Plain is a very important commodity grain base; it went through the large scale devel- opment in the 50s and engineering of dry soil changing into paddy fields in the 80s. A variety of irrigation agriculture development model, including well-irrigation area, irrigation area of well-irrigation, have formed now. In order to develop and use the land and water resources of Sanjiang Plain, in this paper, fuzzy recognition model is used to evaluate groundwater resources carrying capacity. The rank feather val- ue is used to divide the groundwater resources carrying capacity of Sanjiang Plain, and the satisfying result is obtained in the paper.
