张掖绿洲农业的影响因子

农业是张掖的主导产业，在绿洲经济发展中起着举足轻重的作用。近年来，随着人口增加，不合理的土地开垦，粗放的灌溉方式，导致水土资源矛盾突出，农业生态环境恶化。本研究基于张掖农业背景的基本资料，选取了与绿洲农业生产相关的9个因子进行分析。首先，选择主成分分析方法，探讨各个因子对绿洲农业生产的影响。其次，选用灰色关联方法，以农业总产值为参考指标，其他各因子作为比较指标，分析各因子与农业总产值的关联度。在此基础上，综合两种方法分析的结果，提出促进张掖绿洲农业协调发展的4项具体对策措施。

Analysis of factors affecting oasis agricultural development and countermeasure in Zhangye

Agriculture is the leading industry in Zhangye, which plays an important role in oasis economic development. Recently, the population growth, irrational land reclamation and extensive irrigation have led to the obvious contradiction between water and land resources. Based on the present agricultural development background, nine factors of Zhangye oasis agriculture system were chosen and analyzed. Firstly, we used the principal component analysis to investigate the impacts of different factors on oasis agriculture. Secondly, taking agricultural output as a reference indicator and others as comparable indicators, the correlations of each factor and oasis agriculture were analyzed based on grey relative analysis method. Summarizing the results of two methods, we bring up four measures to coordinating the development of Zhangye oasis agriculture.
