Abstract: The paper establishes a comprehensive evaluation model of meadow resources using the fuzzy mathematical method,and then applies the model to the dynamic evaluation of subalpine meadow in Huapo, Qinyuan county, Shanxi.The results indicate that the meadow resources in most different slopes and different months are evaluated as "good".As the evaluation result is the subordinate degrees of the evaluated meadow that belong to different grades respectively,the meadow resources in a same grade can be compared further.The comparisons of the evaluation results in the same month and the different slopes or in the same slope and the different months can provide scientific basis for the grazing plan in grazing management.Furthermore,the model provide a new method for the comprehensive evaluation of meadow resources.

Key words: Subalpine meadow, Comprehensive evaluation, Evaluation index

摘要： 应用多层次模糊综合评价方法建立草地资源的综合评价模型,对山西沁源县华城乡亚高山草甸植被利用进行动态评价。结果表明,试验区除个别月份和少数坡向的草地属优等和中等外,其余月份和坡向均属良等。由于评价结果是评价对象分别属于各个不同等级的隶属度,因此,同一等级的草地还可以进一步比较。通过对同月不同坡向和同一坡向不同月份评价结果的比较,可为制定全年的放牧计划提供科学依据。同时,也为草地资源综合评价提供一种新的方法。
