安徽淮北地区农田水资源调控模式研究

Regulation Modes of Farmland Water Resources in North Huaihe River Area of Anhui Province

淮北地区存在水旱灾害频繁、水资源供需矛盾突出及其开发利用不合理等方面的问题。根据该地区自然条件、降水、土壤、水文地质、水资源条件、农业生产特征和社会经济条件等差异,全区划分为北部、中部和南部3个研究分区,提出北部“以蓄为主、以蓄促补”,中部“蓄泄兼筹、补排相顾、以蓄为主、适度排泄”,南部“以排为主,蓄、引、提相结合,洪、涝、渍、旱综合治理”的分区农田水资源调控模式。这对该区农田水利的发展具有重要的参考价值。

High frequency flood and drought, severe scarcity of water resources and irrational development occur in North Huaihe River Area of Anhui Province. According to the differences of nature condition, precipitation, soil, hydrogeologic conditions, water resources condition, agriculture production characteristic, social and economic condition, three research areas, north section, central section and south section, are plotted out. Regulation modes of farmland water resources are laid out. Storage water is main and supplement water is promoted by storage in north section. In central section, storage water and discharge water are given attention to two or more things, supplement water and discharge water are planned as a whole, storage water is main and discharge water is within measure. In south section, discharge water is mostly, storage water, water diversion and water raising are united, flood, water logging and drought are improved comprehensively. These results are important worth for its progress of irrigation and drainage.
