【摘要】：土地資源是維持人類生存的主要資產(chǎn),而土地的空間差異性則決定了土地的最終用途。國(guó)民經(jīng)濟(jì)的發(fā)展需要各種資源,而資源的開采必然帶來(lái)土地資源的破壞。礦區(qū)土地復(fù)墾也成為我國(guó)生態(tài)環(huán)境和礦山可持續(xù)發(fā)展的重要問(wèn)題。復(fù)墾礦區(qū)土地適宜性評(píng)價(jià)是土地復(fù)墾項(xiàng)目投資前期工作的中心環(huán)節(jié)和項(xiàng)目決策的依據(jù),是土地復(fù)墾規(guī)劃的核心工作,對(duì)搞好土地復(fù)墾工作的實(shí)施、合理配置復(fù)墾區(qū)土地資源具有重要的意義。本文以土地適宜性評(píng)價(jià)為研究對(duì)象,通過(guò)對(duì)國(guó)內(nèi)外文獻(xiàn)的剖析,提出了土地適宜性評(píng)價(jià)的指標(biāo)體系及模糊綜合評(píng)價(jià)方法。我國(guó)幅員遼闊,各個(gè)地方土地的自然地理情況千差萬(wàn)別,據(jù)此,本文提出以待評(píng)估土地為目標(biāo)進(jìn)行指標(biāo)篩選,通過(guò)專家打分及層次分析法來(lái)確定待評(píng)估項(xiàng)目的指標(biāo)權(quán)重,并采用模糊綜合評(píng)價(jià)方法確定待評(píng)估土地的用途,并以龍洞礦區(qū)為例進(jìn)行了實(shí)例分析。土地適宜性評(píng)價(jià)涉及到非常多的因素,氣候、緯度、海拔、降水、公用設(shè)施等多方面的影響。傳統(tǒng)的土地適宜性評(píng)價(jià)往往采用統(tǒng)一的指標(biāo)體系,難以根據(jù)實(shí)際情況做出客觀的評(píng)價(jià)。本文在研究中采取了先構(gòu)建指標(biāo)集,然后根據(jù)實(shí)際情況由專家進(jìn)行指標(biāo)篩選及權(quán)重確定,最后采取模糊綜合評(píng)價(jià)的方法對(duì)待評(píng)估土地做出評(píng)價(jià)。該方法提高了土地適宜性評(píng)價(jià)的準(zhǔn)確性,能夠更加客觀的反映土地的實(shí)際用途,期望對(duì)非金屬礦山的土地適宜性評(píng)價(jià)提供有益的參考。
[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.
