Ecological Suitability Evaluation of Urban Construction Land Based on GIS

Abstract: [Purposesl Quantitative analysis and evaluation of the ecological suitability of construction land provides a reference for addressing the contradiction between urban expansion and limited land resources.[Methods] Taking Lu'an City asa case study,the ecological suitability of urban construction land was calculated with the support of GIS by selecting the influencing factors of urban construction land,using the ANP method to determine the weights of each influencing factor and constructing an evaluation index system.Findings] The results show that most of the suitable construction areas are distributedin theurbanarea of Lu'an Cityand the countiesunder its jurisdiction,the suitableconstruction areas are primarily developed land with a strong economic foundation and high development level.The moderately suitable construction areasare close to the central plain hils and basins or the area with more fragmented terrain,with diverse terrain and no distinct characteristics,and the slope is mostly 8°～ （20 （202 20° ; The main characteristics of the prohibited construction area are areas with high terrain altitude or steep slopes,which are mostly distributed in the mountainous areas of the north and south.[Conclusions] In the future,Lu'an City should focus on optimizing construction land from aspects such as urban planning,ecological spatial planning,balancing resources and environmental factors and enforcing ecological red-line policies.

Keywords:construction land; ecological suitability; Lu'an City

我國(guó)城市數(shù)量多，類型復(fù)雜，發(fā)展水平各不相同[1]，不同城市在進(jìn)行城市建設(shè)用地適宜性評(píng)價(jià)時(shí)所采用的評(píng)價(jià)指標(biāo)體系與合成計(jì)算方法也有所不同[2，但總體的評(píng)價(jià)指標(biāo)基本是從經(jīng)濟(jì)、社會(huì)等人文因素進(jìn)行定性描述，而重點(diǎn)針對(duì)生態(tài)系統(tǒng)、生態(tài)環(huán)境等方面的評(píng)價(jià)因素較少且對(duì)GIS的空間分析及可視化技術(shù)利用不充分[3]。（剩余6297字）
