摘　　要：广西现有耕地面积6538万亩,有效灌溉面积2583万亩,其中30万亩以上的灌区343万亩,1万亩以上的中型灌区795万亩,1万亩以下的小型灌区1445万亩。本文以最严格水资源管理制度控制下的灌溉可供水量为约束,结合灌溉水利用系数、灌溉净定额、规划种植结构等分析成果,按以水定地的原则,合理规划广西全区灌溉面积,结合各设区市的发展需求及条件,科学布局大中小型灌区。Guangxi has cultivated land of 65.38×10^(6)mu and effective irrigated area of 25.83×10^(6)mu at present,of which the irrigation zones each with an area above 300 thousand mu have a total area of 3.43×10^(6)mu,the mid-scale irrigation zones each with an area above 10 thousand mu have a total area of 7.95×106mu,the small-scale irrigation zones each with an area below 10 thousand mu have a total area of 14.45×10^(6)mu.In this paper,with the irrigation water supply limited by the strictest water resources management system as constraint condition,combined with the analysis results of irrigation water utilization coefficient,net irrigation quota and planned irrigation structure,accord⁃ing to the principle of determining land by water,the irrigation area of Guangxi is properly planned;layout of the large-,mid-and small scale irrigation zones are conducted combined with the development demands and condi⁃tions of various cities.
