摘要
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。通过对我国南方四个草地类型具体计算表明,该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。
Having reviewed briefly the evaluation of the natural grass land resources of china,we turn out attention mainly to those factors that play an important part in the evaluation of these resources.A mathema- tical model of three-stage multifaetorial evaluation of the natural grassland resources is proposed here by exploiting the relationships among those factors.It is the first time that such a mathematical model has been ap- plied to the overall evaluation of these natural resources in South China. To verify the accuracy of the model,we evaluated four types of the res- ources according to this model and a description of the process ofcomputati- on in detail is given.It is proved that the model is highly accurate and is suitable for the evaluation of the natural grassland resources of South China.
