【摘要】：城鄉(xiāng)建設用地適宜性評價是指導城鄉(xiāng)規(guī)劃發(fā)展方向的一項基礎性工作,越來越得到眾多城市建設者和學者們的關注。隨著我國城鎮(zhèn)化步伐加快,對土地需求越來越多,使得各地資源、環(huán)境、人口與土地利用的矛盾日漸深化,城鄉(xiāng)建設用地需求與嚴格保護耕地的矛盾也更加尖銳。城鄉(xiāng)建設用地作為建設用地的一種重要類型,其能否正常有序合理發(fā)展,嚴重影響一個地區(qū)經濟發(fā)展的質量與效率。因而,開展城鄉(xiāng)建設用地適宜性評價對協(xié)調好發(fā)展與保護兩者的矛盾意義重大。本文在綜合分析前人評價研究相關理論和方法的基礎上,選擇內蒙古自治區(qū)鄂爾多斯市東勝區(qū)作為研究區(qū),以建設用地適宜性為評價目的,以城鄉(xiāng)建設用地為評價對象,針對評價區(qū)域自身的特點,綜合考慮自然、社會、生態(tài)環(huán)境條件等因素,進行了相關研究和探討。采用多因素綜合評價模型,選取自然環(huán)境因素、社會經濟因素、生態(tài)環(huán)境因素和限制因素等4個指標層,按照評價因子選取原則,并進一步選擇地表沉陷、地災危險性、坡度、土壤侵蝕強度、景觀空間格局、水環(huán)境影響范圍、基本農田保護等多個具體因子,構建了評價指標體系,確定了權重,運用GIS軟件開展了評價工作。將研究區(qū)城鄉(xiāng)建設用地級別分為最為適宜(I等)、比較適宜(II等)、基本適宜(III等)、勉強適宜(IV等)、最不適宜建設(V等)和禁止建設(VI等)6個等級,分別計算出各等級面積及占比。研究結果表明:a)I、II、III、IV、V、VI等用地占評價區(qū)域總面積的比例分別為6.32%,12.14%,24.12%,16.43%,18.81%和22.18%。評價區(qū)域內適宜建設地(I、II、III、IV等地)總面積為126291.06公頃,不宜建地(V等、VI等)為87714.15公頃,分別占評價區(qū)域土地面積的59.01%和40.99%。b)在適宜建設的用地中,I等城鄉(xiāng)建設用地13534.09公頃,占適宜建設地的10.72%;II等城鄉(xiāng)建設用地25983.06公頃,占適宜建設地的20.57%;III等城鄉(xiāng)建設用地51615.70公頃,比例為40.87%;IV等城鄉(xiāng)建設用地35158.21公頃,占宜建地的27.84%。由此可見,研究區(qū)適宜的城鄉(xiāng)建設用地主要以III等用地為主。c)從用地分布來看,I等用地主要分布在主城區(qū)(建成區(qū))及其周邊、罕臺鎮(zhèn)南部等區(qū)域,城區(qū)東南、西南部有較少分布,另外在主要的交通道路兩側開闊區(qū)域也有零星分布。II等用地主要分布在城區(qū)周邊地區(qū);III等用地主要分布在泊江海子鎮(zhèn)中部偏東、罕臺鎮(zhèn)西南部以及銅川鎮(zhèn)東部,土地利用率不高。IV等用地主要分布在泊江海子鎮(zhèn)中部、銅川鎮(zhèn)北部及西南部,這部分地區(qū)勉強適于建設,需要利用經濟和技術手段改善。V等用地主要分布在銅川鎮(zhèn)中部區(qū)域及泊江海子鎮(zhèn)中部偏西區(qū)域,這部分地區(qū)處于礦產資源開采區(qū),分布著很多礦藏,地質災害較多。VI等用地主要分布在泊江海子鎮(zhèn)北部和西南部,這些地區(qū)有國家自然歷史文物保護區(qū)、基本農田保護區(qū),以及相關法律法規(guī)禁止用作建設。因此,在選擇城鄉(xiāng)建設用地時應避開這些地方。基于以上分析,提出研究區(qū)城鄉(xiāng)建設用地開發(fā)利用方向:可以以建成區(qū)為核心,南北軸向發(fā)展,并以向南方向發(fā)展為主,適當向城區(qū)東南及西南方向建設發(fā)展。通過本評價研究,不僅在一定程度上可以為研究區(qū)域的用地規(guī)劃提供決策依據,還可為盟市類似地區(qū)的相關用地評價提供參考和研究思路。
[Abstract]:The suitability evaluation of urban and rural construction land is a basic work to guide the development of urban and rural planning. With the acceleration of the urbanization of our country, the demand for land is getting more and more, so that the contradiction between the resources, the environment, the population and the land use is deepening, and the contradiction between the needs of the urban and rural construction land and the strict protection of the cultivated land is also more acute. As an important type of construction land, the construction land of urban and rural areas can be properly and orderly developed, which seriously affects the quality and efficiency of economic development in a region. Therefore, it is of great significance to carry out the evaluation of the suitability of the urban and rural construction land to coordinate the development and protection of the urban and rural areas. On the basis of comprehensive analysis of the relevant theories and methods of the previous evaluation, this paper selects the Dongsheng District of the Inner Mongolia Autonomous Region as the research area, and takes the land suitability as the purpose of evaluation, and uses the urban and rural construction land as the evaluation object, and aims at the characteristics of the evaluation area itself. In the light of the factors such as nature, society and ecological environment, the relevant research and discussion have been carried out. a multi-factor comprehensive evaluation model is adopted, and four index layers such as natural environment factors, socio-economic factors, ecological environment factors and limiting factors are selected, the principle of the selection of the evaluation factors is selected, the surface subsidence, the disaster risk, the slope and the soil erosion intensity are further selected, The evaluation index system is built, the weight is determined, and the evaluation work is carried out by using the GIS software. The land level of urban and rural construction in the study area is divided into the most suitable (I, etc.), the appropriate (II, etc.), the basic fitness (III, etc.), the barely appropriate (IV, etc.), the most suitable construction (V, etc.) and the prohibition of construction (VI, etc.), and the area and proportion of each grade are calculated respectively. The results showed that: a) The proportion of land used in I, II, III, IV, V, VI was 6.32%, 12.14%, 24.12%, 16.43%, 18.81% and 22.18%, respectively. The total area of the appropriate construction site (I, II, III, IV etc.) in the evaluation area is 126291.06 ha, and it is not suitable for land (V, etc.) of 87714. 15 ha, accounting for 55.9% of the land area of the evaluation area and 40. 99% of the land area of the evaluation area, respectively. b) In the land suitable for construction, I and other urban and rural construction land is 13534. 09 hectare, The construction land for urban and rural construction is 25983. 06 ha, accounting for 20.57% of the construction land, and the construction land for urban and rural construction, such as III, is 51615.70 hectares, the proportion of which is 40. 87%, and the construction land for urban and rural construction, such as IV, is 35158.21 hectares, accounting for 27.84% of the construction land. It can be seen that the appropriate urban and rural construction land in the research area is mainly used for the land of Class III. c) From the land distribution, I and other land are mainly distributed in the main urban area (built-up area) and its surrounding area, and the south-east and south-west of the urban area have less distribution, and there are also sporadic distribution in the open area on both sides of the main traffic road. The land used for Class II is mainly distributed in the surrounding area of the urban area; the land is mainly distributed in the south-western part of the central part of the sub-town of the Pojiang and the south-west of the Hantai Town and the east of the town of Tongchuan, and the land utilization rate is not high. The land, such as IV, is mainly distributed in the middle of the sub-town of Pojiang, and the north and south-west of Tongchuan Town. This part of the land is barely suitable for construction and needs to be improved by economic and technical means. The land, such as V, is mainly distributed in the central part of the town of Tongchuan and the west of the central part of the town of Pojiang. This part of the land is in the mining area of the mineral resources, with a large number of mineral deposits and more geological hazards. The land, such as VI, is mainly distributed in the north and the south-west of the sub-town of Pojiang, with the national natural historical and cultural relics protection areas, the basic farmland protection areas, and the relevant laws and regulations, which are prohibited from being used as construction. As a result, these areas should be avoided in the selection of land for urban and rural construction. Based on the above analysis, the development and utilization direction of the urban and rural construction land in the research area is put forward, which can be the core of the built-up area, the north-south axial development, and the development of the south to the south and the south-west direction as appropriate. Through this evaluation, not only the decision-making basis for the land planning of the study area can be provided to a certain extent, but also the reference and the study thought can be provided for the relevant land evaluation in the similar area of the League.
