【摘要】：居住用地地質(zhì)環(huán)境適宜性評價研究,是對土地的自然屬性和社會屬性進行分析,判斷土地的地質(zhì)環(huán)境是否適宜居住。其影響因素復(fù)雜多樣,包括與居住用地選址相關(guān)的各類地質(zhì)環(huán)境要素的總體。居住用地地質(zhì)環(huán)境宜性評價已成為居民點選址規(guī)劃、土地利用和發(fā)展的基礎(chǔ)。美姑縣位于四川省涼山州境內(nèi),地處青藏高原東南橫斷山脈與四川盆地西南邊緣交匯處,構(gòu)造活動強烈、地貌類型多變、地質(zhì)災(zāi)害頻發(fā),城鄉(xiāng)建設(shè)需要面對很多環(huán)境工程地質(zhì)問題。美姑縣居住用地發(fā)展速度均受山區(qū)生態(tài)承載力、地質(zhì)地貌適宜性、開發(fā)難易程度和道路通達性等因素的限制。美姑縣居住用地受崩塌、滑坡、泥石流及不穩(wěn)定斜坡等地質(zhì)災(zāi)害影響嚴(yán)重,地質(zhì)環(huán)境要素對美姑縣人居環(huán)境安全尤為重要。本文從美姑縣地質(zhì)環(huán)境因素的角度出發(fā),側(cè)重對其居住用地地質(zhì)環(huán)境的因子分析,對美姑縣居住用地進行適宜性研究。論文在分析總結(jié)國內(nèi)外研究現(xiàn)狀的基礎(chǔ)上結(jié)合美姑縣現(xiàn)狀,著重分析了影響美姑縣居住用地適宜性的地質(zhì)環(huán)境因素,構(gòu)建了居住用地地質(zhì)環(huán)境適宜性評價體系。論文選取地質(zhì)條件、地形地貌和其他因素作為評價指標(biāo),共包含10個評價因子,運用層次分析法(AHP)確定各評價因子的權(quán)重,然后使用指標(biāo)指數(shù)法計算出適宜性分值,根據(jù)綜合分值將全縣分為居住用地地質(zhì)環(huán)境適宜區(qū)、居住用地地質(zhì)環(huán)境較適宜區(qū)和居住用地地質(zhì)環(huán)境不適宜區(qū),其中居住用地地質(zhì)環(huán)境適宜區(qū)共10個鄉(xiāng)鎮(zhèn),居住用地地質(zhì)環(huán)境較適宜區(qū)共11個鄉(xiāng)鎮(zhèn),居住用地地質(zhì)環(huán)境不適宜區(qū)共15個鄉(xiāng)鎮(zhèn)。在適宜性分區(qū)的基礎(chǔ)上提出居住用地分區(qū)調(diào)控模式,對美姑縣居住用地地質(zhì)環(huán)境適宜區(qū)提出重點發(fā)展模式;較適宜區(qū)提出限制發(fā)展模式;不適宜區(qū)提出綜合治理模式。最后,針對美姑縣居住用地地質(zhì)環(huán)境不適宜區(qū)提出地質(zhì)環(huán)境整治方法,主要包括工程治理、避險搬遷和地質(zhì)環(huán)境保護。
[Abstract]:Residential land suitability evaluation of geological environment research is carried on the analysis to the land of the natural and social attributes of geological environment, whether judge land suitable to live in. The influence factors are complex and diverse, including residential land and location related to various geological environmental elements. The overall residential land suitability evaluation of geological environment has become the residents location based planning, land use and development. Meigu county is located in the territory of Sichuan Prefecture of Liangshan Province, located in the southeast of the Qinghai Tibet Plateau and Hengduan Mountains southwest of Sichuan basin edge interchange, strong tectonic activity, landform changeable, geological disasters, urban and rural construction needs to face many problems of environmental engineering geology. Meigu County residential land development speed by the mountain ecological capacity, geological suitability, development difficulty and road access restrictions and other factors. In Meigu County, residential land by the collapse, landslide, mud Stone flow and unstable slope geological disasters seriously affected, geological environment is particularly important for Meigu County safe living environment. This paper from the geological environment factors Meigu County perspective, focusing on its living by factor analysis to the geological environment, studied the suitability of Meigu County residential land. Based on the research status at home and abroad the Analysis on the combination of Meigu county situation, analyzes the impact of Meigu County residential land suitability of geological environment factors, the construction of residential land geological environment suitability evaluation system. This paper selects the geological conditions, topography and other factors as the evaluation index, a total of 10 evaluation factors, AHP (AHP) to determine the weight of each evaluation factor, and then use the index method to calculate the suitability score, according to the comprehensive score of the county is divided into residential land suitability of geological environment area, residential With the geological environment is more appropriate area and the residential area of land is not suitable for the geological environment, the geological environment suitability of residential land area of a total of 10 villages and towns, residential land geological environment suitable area a total of 11 towns, residential land geological environment suitable for a total of 15 villages and towns. Based on Suitability zoning is put forward on the residential land use zoning control mode of Meigu County residential land geological environment suitability area is put forward on development model; suitable area proposed to restrict the development of mode; unsuitable area put forward comprehensive control model. Finally, the proposed method is not suitable for area geological environment for geological environment in Meigu county live, including project management, hedge relocation the geological and environmental protection.
