【摘要】 持续利用草地资源是我国实现持续发展战略的基本保障之一。在我国农牧交错带发展中,将可持续发展的基本理论应用到我国草地利用管理的实践,建立草地持续利用的评价指标体系和定量评价方法,对保证社会持续发展具有重要的意义。在建立农牧交错带草地资源可持续利用定量评价指标体系基础上,运用模糊数学分析手段,深入研究农牧交错带草地资源的可持续利用程度是定量评价目标。本项研究课题为探索建立一套政府对农牧交错带草地资源可持续利用新的核算体系管理制度奠定理论基础。也是支持进行国际交流和相关谈判的科学基础,这是本文选题的目的。由于建立农牧交错区草地资源可持续利用指标体系和定量评价方法在国内处于空白,是本文创新点。 按照草地生态恢复和建设有原理,在建立农牧交错区草地资源可持续利用评价指标体系框架基础上,对草地可持续利用状况进行定量化评价,评价农牧交错区草地资源的可持续利用程度。主要方式是制定草地可持续利用评价原则, 用 AHP 法建立评价指标体系,对初级指标群进行评分,建立比较判断矩阵,通过矩阵运算,计算出各层指标与目标层指标相对优劣的排序权值,运用模糊数学的隶属度函数,计算出最终评定结果。 农牧交错区草地资源可持续利用能力指标体系分为总体层、系统层、状态层和要素层四个层级。本课题采用了 39 个要素指标,全面系统地对于这些指标进行了定性描述,构成了指标体系的基础要素。草地资源可持续利用指标体系分别从不同侧面、不同角度反映农牧交错区居民对草地资源开发利用可持续状况、草地自然生态系统造成的危害、人类在协调与自然关系中所作的努力和取得的成绩,以及在贯彻代内公正和代际公正的情况等。草地资源可持续利用指标体系建设完善了农牧交错区经济社会可持续发展指标的重要内容。对内蒙古农牧交错区不同地域草地资源可持续利用能力空间差异进行定量描述。从科学发展观的要求出发,对不同生态地域草地可持续利用状况和经济社会发展模式进行综合评判。 内蒙古农牧交错地区不同生态经济地域草地资源可持续利用能力空间差异综合评价的结果,可为我国农牧交错带区域发展战略、中长期发展规划、资源可持续开发利用法规、政策制定上提供科学依据。更多还原

【Abstract】 Sustainable utilization of grassland resources has been one of the basic strategies for a sustainable development in China. For the sustainable development in the cropping-pastoral interlacing regions, the establishment of a data-based system for sustainability evaluation is urgently needed. In this paper, a series of quantitative indexes were selected to test the applicability of the system by fuzzy mathematic models. This model system was considered to be useful for a number of occasions, including international scientific exchange and negotiations. This is the primary purpose of this study. The setting up of such a system is an innovated approach internationally and domestically. According to the grassland recovery and reinstallation principles and based on the frame of resource sustainable utilization assessment, sustainability of grassland resources was quantitatively evaluated, and further more, sustainability of the grassland resources in the cropping-pastoral interlacing regions were assessed. The main steps involved in the system include: identifying sustainability guideline, establishing evaluating indexes by AHP method, quantitatively evaluating the primary index groups, establishing comparing and identification matrixes, weighting the correlations between indexes at different levels by matrix operation, applying hierarchical functions, and making up the final evaluation results. The evaluation system for the sustainability in the cropping-pastoral interlacing regions is a 4-leveled system, composed of 39 elemental indexes. All these indexes were described systematically and were selected as the basic indexes in the system. Sustainability of the resources, damages to the grassland ecosystem, efforts and achievements made by the human being, and the fairness between generations for using grassland resources in the cropping-pastoral interlacing regions was reflected and evaluated from different angles in this system. Social-economical sustainability in the cropping-pastoral regions was scientifically assessed with this system in different ecological zones in Inner Mongolia. The evaluated results with this system can be used as references for government policy making in various aspects such as regional developmental strategy, mid-long term developmental planning, resources exploration, and etc.更多还原
