亚热带草地资源综合评价的数学模型

Mathematical Model for Multifactorial Evaluation of Nat- ural Grassland Resources in Subtropics.

本文在前人工作的基础上,对亚热带草地资源评定因素进行了筛选与合理组合,编排了各评定因素的多层次评判顺序,组建了综合评价草地资源的模糊数学模型。首次应用数学模型对我国亚热带草地资源进行了综合评价。为验证该数学模型的灵敏度,笔者列举了我国南方四个草地类型,作了具体计算。结果表明,数学模型本身具有较高的灵敏度,完全可以用于评价我国南方天然草地资源。

On the basis of reviewing the evaluation of the natural grassland resources of China, the evaluation factors for subtropic grassland resources were screened and properly combined. A mathematical model of three- stage multifactoral evaluation of the natural grassland resources is established through exploiting the relationships among those factors. To verify the accuracy of the model, four types of the resources were evaluated according to the model,and a description of the process of computation in detail is given.
