| Abstract: |
| Determination of the soil correction coefficient is vital to evaluate the land potential productivity.Using the law of potential weaken and index weight analysis the agricultural resources conditions of Hetian development zone, we also estimate the land potential productivity and derterminate soil correction cofficient.The land potential productivity is 301.11 kg/hm2 under the natural precipitation and 8312.74 kg/hm2 under the irrigation condition.The soil correction cofficient is f (s) =0.4199.On the basis of this, we put forward the main measures of improving the land potential productivity. |
