Optimized Allocation Model for Regional Agricultural Fertilizer Resources in Southern Xinjiang from the Perspective of Sustainable Development

基于可持续发展的南疆区域农业肥料资源优化配置模型研究(英文)

[Objective] This study was to establish an optimized model for the allocation of agricultural fertilizer resources in Southern Xinjiang from the perspective of sustainable development.[Method] An optimized model for the allocation of agricultural fertilizer resources was established based on their allocation structure.Combined with the actual agricultural production in Aksu areas of Southern Xinjiang,by establishing a rational evaluation index system,under the premise of considering the planting area constraints,the total water resources constraints and the security constraints of food production,we established the empirical optimal allocation model of the regional agricultural fertilizer resources in Aksu area of Southern Xinjiang.Moreover,we solved the model by using the search algorithm of computer and lingo programming.[Result] The increased economic benefit was near to 1.8 billion Yuan by adopting the optimal allocation methods,with a relative increment of about 34.4%.[Conclusion] Our results provided theoretical basis for achieving the sustainable development of agricultural economy in Southern Xinjiang.

[目的]建立基于可持续发展的南疆区域农业肥料资源优化配置模型。[方法]给出了区域农业肥料资源的优化配置结构,并在此基础上建立了区域农业肥料资源的优化配置模型;结合南疆阿克苏地区农业生产实际,在考虑种植面积约束、水资源总量约束和粮食生产安全约束的前提下,建立了南疆阿克苏地区农业肥料资源优化配置的实证模型,并采用计算机搜索算法,通过Lingo编程对该模型进行了求解。[结果]优化配置后产生的经济效益较配置前增加了近18亿,相对增量约为34.4%。[结论]该研究结果为实现南疆农业经济的可持续发展提供了理论依据。
