川西北民族地区农业结构系统分析及优化

在介绍川西北民族地区概况的基础上，剖析了川西北民族地区农业发展现状，具体包括农业自然资源丰富、农业经济增长缓慢2个方面。通过对川西北地区农业结构分析发现，该地区种植业生产效率和经济效益低下，畜牧业作为牧区的主要产业，其生产效益较高，农业生产还处于资源导向型阶段；农业生产结构是以牧业为主的农牧结构，种植业以谷物、薯类为主，畜牧业以奶业和牛肉业为主；川西北民族地区具有发展谷物、豆类、水果、牛肉、羊肉、奶肉6个产业的比较优势，其中，水果、牛肉、奶业3个产业的区位商值在加大，产业比较优势逐步加强，谷物、豆类、羊肉3个产业的区位商值有所下降，产业比较优势较为稳定。为了促进川西北地区农业向深度、广度发展，提出了以下对策与建议：一是走现代畜牧业发展道路；二是适度提高经济作物比重；三是加快发展绿色食品加工业。

Systematic Analysis and Optimization of the Agricultural Structure in Ethnic Regions in Northwest Sichuan Province

Based on introducing the basic conditions of the ethnic regions in northwest Sichuan Province,the thesis analyzes its agricultural development status,which can be classified into two aspects-rich natural resources and slow agricultural economic growth.Through the analysis of the agricultural structure of northwest Sichuan Province,it is found that the production efficiency and economic benefits of crop planting in this region are low,animal husbandry,as a major industry in pastoral region,sees high production efficiency,the agricultural production is still at the resource-oriented stage; its agricultural structure is still the farming-pastoral structure relying mainly on animal husbandry,planting is dominated by crop planting and potato planting,animal husbandry mainly produces dairy and beef; the ethnic regions in northwest Sichuan Province is endowed with the advantages to grow crops,beans and fruits as well as to produce beef,mutton and milk,among which,three industries,say fruit,beef and dairy are with increasing location quotient and gradually strengthening industrial comparative advantage,while the location quotient of the other industries is declining and their industrial comparative advantages are more stable.In order to promote the agriculture in northwest Sichuan Province to develop in breadth and depth,the thesis proposes the following measures and suggestions:the first one is to adhere to the development strategy of modern animal husbandry; the second is to appropriately improve the proportion of economic crops; the third is to accelerate the development of green food processing industry.
