| 摘 要： | 运用灰色系统理论及方法,基于生态学家、经济学家对内蒙古草原生态服务边际量指标体系、数理模型及相对重要性的评价和判断,创建草原生态服务边际量的数学模型系统。选取1947—2006年期间统计数据,测算过去60 a内蒙古草原生态服务的判明值,分析其基本演替轨迹。结果表明,60 a来内蒙古草原生态服务变迁过程基本遵循早期缓慢水平下降,中期快速曲线下降,后期骤然快速直线下降的演替轨迹。同时,分析了内蒙古草原生态服务"M"形波浪式下降原因的草原开垦之说。 |

| Abstract: | In view of evaluation and judgment that some ecologists and economists made to the mathematical models,index system and indices weight of ecological services marginal value,a model of grassland ecological services marginal value for Inner Mongolia was established with the Grey System Theory in this paper.The model was applied to evaluate the ecological services of Inner Mongolia steppe in the last 60 years based on statistical data from 1947 to 2006.The result shows that there was a generally descending tre... |
