【摘要】：土地资源是维持人类生存的主要资产,而土地的空间差异性则决定了土地的最终用途。国民经济的发展需要各种资源,而资源的开采必然带来土地资源的破坏。矿区土地复垦也成为我国生态环境和矿山可持续发展的重要问题。复垦矿区土地适宜性评价是土地复垦项目投资前期工作的中心环节和项目决策的依据,是土地复垦规划的核心工作,对搞好土地复垦工作的实施、合理配置复垦区土地资源具有重要的意义。本文以土地适宜性评价为研究对象,通过对国内外文献的剖析,提出了土地适宜性评价的指标体系及模糊综合评价方法。我国幅员辽阔,各个地方土地的自然地理情况千差万别,据此,本文提出以待评估土地为目标进行指标筛选,通过专家打分及层次分析法来确定待评估项目的指标权重,并采用模糊综合评价方法确定待评估土地的用途,并以龙洞矿区为例进行了实例分析。土地适宜性评价涉及到非常多的因素,气候、纬度、海拔、降水、公用设施等多方面的影响。传统的土地适宜性评价往往采用统一的指标体系,难以根据实际情况做出客观的评价。本文在研究中采取了先构建指标集,然后根据实际情况由专家进行指标筛选及权重确定,最后采取模糊综合评价的方法对待评估土地做出评价。该方法提高了土地适宜性评价的准确性,能够更加客观的反映土地的实际用途,期望对非金属矿山的土地适宜性评价提供有益的参考。
[Abstract]:Land resources are the main assets to maintain human survival, and the spatial difference of land determines the end use of land. The development of national economy needs all kinds of resources. The exploitation of resources will inevitably lead to the destruction of land resources. Land reclamation in mining areas has also become an important issue of ecological environment and sustainable development of mines in China. The evaluation of land suitability in reclamation mining areas is the early stage of investment in land reclamation projects. The central link of the project and the basis for the project decision, Land reclamation planning is the core work of land reclamation planning, which is of great significance to the implementation of land reclamation work and the rational allocation of land resources in reclamation areas. This paper takes the evaluation of land suitability as the research object, through the analysis of domestic and foreign literature. This paper puts forward the index system of land suitability evaluation and the fuzzy comprehensive evaluation method. Our country has a vast territory, and the physical and geographical conditions of each place vary greatly. Based on this, this paper puts forward that the target is to select the land to be evaluated. The index weight of the project to be evaluated is determined by expert scoring and analytic hierarchy process, and the use of the land to be evaluated is determined by the fuzzy comprehensive evaluation method. The evaluation of land suitability involves many factors such as climate, latitude, altitude, precipitation, and so on. The traditional land suitability evaluation often adopts a unified index system, which is difficult to make objective evaluation according to the actual situation. Then according to the actual situation, the experts select the index and determine the weight. Finally, the fuzzy comprehensive evaluation method is adopted to evaluate the land, which improves the accuracy of the land suitability evaluation. It can reflect the actual use of land more objectively and provide a useful reference for the evaluation of land suitability in non-metal mines.
