摘要: 探讨沙漠化发生地区农、牧、林经济结构有着重要意义。合理的经济结构具有较高的总体功能,而且在发展生产过程中,能促进环境的整治;反之,经济结构不合理会带来总体功能降低和破坏资源的恶果。特别是中国共产党第十二次代表大会上明确提出了在本世纪末我,国经济建设的战略目标以后,在生态失调的沙漠化地区如何实现,既达到恢复环境又发展经济的双重效果,研究农、林、牧生产的合理结构就更有现实意义。本文试以农、牧交错沙漠化地区的陕北榆林县为例,应用线性规划对此问题进行探讨。线性规划的数字抽象含义是求得某组未知数(X1X2、°°°°°°Xn)使其满足约束条件,并使目标函数取得最大(或最小)值。线性规划广泛应用于经济规划、工业工程等方面方案选优上,对建立合理的(最优)农业经济结构1)同样适用。但由于此项研究工作开展较晚、资料缺欠,所得结果仅供参考。

Abstract: Taking the Mangkeng brigade of Qinhe of Yulin county the interlacing agriculture-stock-raising desertified area as an exahiple and according to the conditions of natural and social resources as well as the special demands for environmental rehabilitation, this paper discussed the economic structure of agricult u re in the area mentioned above by using the math ematical model of linear programming with electronic computer.The computer's calculation shows that, by the end of the century, the land coverage of agriculture, forestry and grazing are in the ratio of 10-20:40:50-40 and the income 50-80:20:30-20.
