摘要
根据干旱沙区农林牧业协调发展的原则,以盐池县北部干旱风沙区集中的乡镇现行农业生产状况为基础,以农林牧总体经济纯效益最高为目标,在土地面积、社会需求等约束之下,进行了种养结合的优化设计。系统优化后生产能力增强,粮食总产量将达到3.47万t,比基期的3.08万t多增加了0.39万t;人工牧草由基期的1.31万t增加到优化后的1.65万t;作物秸秆由3.54万t增加到4.16万t,有利的促进了畜牧业的发展。优化结构可获得总净产值1.47亿元,比优化前1.33亿元增加了1 400万元;人均净产值2 344元比优化前1 701元多增加643元。
According to the principle of coordinated development of agriculture, forestry and animal husbandry in arid sandy area, with the agricultural situation of Yanchi county and the base and the goal of the highest benefit of agriculture,forestry and animal husbandry,the optimization design was carried out. By optimizing the system,the total grain output will reach 34 700 t,increasing 3900t;artificial herbage increased from 13100 t to 16500 t;crop straw stalk increased from 35400 t to 41600 t, which improved the development of animal husbandry greatly. After optimized the structure,the net output value 0. 147 billion Yuan can be obtained,increasing 14 million Yuan; the average per capita of output value increased from 1701 Yuan to 2344 Yuan.
