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.
