| Abstract: | The Stndy of the leading
factors of soil ecosystem for Haloxylon ammodeneron and Cistanche deserticola habitat in
Jilantai region is based on the application of the method of grey relational gradation,the
important part of grey system theory.The results show that this method is feasible and easy to
operata.The analyzed results are in a good agreement with the actural conditions.The relational
order on which soil factors of Haloxylon ammodendron forestry affected the high growth of it
is:Content of phosphorus>pH>Unit weight>Content of nitrogen>organic substance>Content of
Potassium>content of salt>Content of water.\=\ \ |
