新疆和田开发区土地生产潜力评价与土壤修正系数的确定

Evaluating the land productive pontential and derterminating the soil correction coefficient in Hetian development zone,Xinjiang

土壤修正系数的确定是土地生产潜力评价的关键。采用潜力衰减法和权重法对和田开发区的农业资源条件进行分析,初步估算在自然降水和灌溉条件下该区的土地生产潜力分别为301.11 kg/hm2和8 312.74kg/hm2,土壤修正系数为f(s)=0.4199。在此基础上,讨论了提高本地区土地生产潜力的主要措施。

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/hm^2 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.
