基于层次分析法的呼伦贝尔高平原生态地质环境评价与开发利用建议OA
Eco-geological environment evaluation of Hulunbuir High Plain based on analytic hierarchy process and suggestions for development and utilization
[研究目的]呼伦贝尔高平原生态地质环境较脆弱,存在草原退化、土地沙化问题,干旱气候及畜牧业农业活动都对环境起着控制作用.本次研究为该地区的生态环境保护、社会持续发展提供科学支撑与指导,为以呼伦贝尔平原为代表的干旱半干旱地区的生态地质环境研究提供参考.[研究方法]基于呼伦贝尔高平原地质条件、生态环境、社会活动特点,利用层次分析法构建生态地质环境评价指标的层次结构模型,获得 10 个评价指标的权重值,再运用综合指数法,建立质量指数数学模型,得到呼伦贝尔高平原生态地质环境质量综合评价结果.[研究结果]结果显示,研究区有 84.05%的地区处于Ⅱ类较好质量级别,11.01%的地区处于Ⅲ类一般质量级别,4.94%的地区处于Ⅰ类良好质量级别,无Ⅳ类较差质量地区,说明呼伦贝尔高平原生态地质环境总体处于较好水平;权重计算结果表明,区域生态地质环境质量的主要作用因素为"生态环境",其中"土地利用类型"为作用力最大的影响因子.[结 论]呼伦贝尔高平原整体生态地质环境质量较好,但仍有部分地区受土地利用情况及水资源状况的影响质量一般,针对已有问题,从封沙育草育林、合理安排载畜量及放牧制度、合理开发水资源提出开发利用建议,为呼伦贝尔生态地质环境可持续发展提供参考.
[Objective]At present,the eco-geological environment of the Hulunbuir Plain is relatively fragile,with problems of grassland degradation and land soddenness,and the arid climate and animal husbandry and agricultural activities have a controlling effect on the environment.So this study provides scientific support and guidance for the ecological environmental protection and sustainable social development of the region,and provides a reference for the study of eco-geological environment of the arid and semi-arid regions represented by the Hulunbuir Plain.[Methods]Based on the geological conditions,ecological environment and social activities of Hulunbeier High Plains,this paper utilizes hierarchical analysis to construct a hierarchical structure model of eco-geological environment evaluation indexes,obtains the weight value of each ten evaluation indexes,and then applies the comprehensive index method to establish a mathematical model of quality indexes and obtains the results of the comprehensive evaluation of eco-geological environment quality in Hulunbuir High Plains.[Results]The evaluation results show that 84.05%of the evaluation units in the study area are in the better quality level,11.01%of the units are in the general quality level,4.94%of the units are in the good quality level,and there is no poor quality area,which indicates that the eco-geological environment of Hulunbuir Plateau is in the better level in general;and the results of the calculation of the weights show that"ecological environment"has a dominant role in the quality of the regional eco-geological environment,and"land use type"is the most influential factor.[Conclusions]The overall eco-geological environment of the Hulunbeier High Plains is of good quality,but there are still some areas with general quality due to land use and water resources.In view of the existing problems,we put forward development and utilization suggestions in terms of sealing sand,cultivating grass and forests,rationally arranging the amount of livestock and grazing system,and rationally developing water resources,so as to provide reference for the sustainable development of the eco-geological environment of the Hulunbuir Plateau.
