Study on the optimization of water-saving cropping structure in Weibei dryland——With Changwu County as example
摘要
Abstract
Based on fuzzy optimization theory, with Changwu County as example, the planting structure situation of typical dryland farming region was analyzed. In order to attain the maximum comprehensive benefits in economy, society and ecology, the thesis established a multi-objective fuzzy optimization model of water-saving cropping structure, and concluded the optimized project in the year of 2010, 201 5 and 2020. According to the project, compared with 2007, the crop planting area decreased by 11%, 19% and 24% respectively; economic crop planting area increas ed by 7%, 12% and 17%; and fodder-crop planting area raised by 8%. The utilizat ion efficiency of rainfall ascend from 6.86 kg/(mm*hm2) in 2007 to 14.08 kg/(mm*hm2) in 2020.关键词
