【摘要】：人地关系是城乡建设的基础条件,也是当今社会发展必须直面和探讨的问题,,人多地少是我国目前最直接的资源状况,人地关系矛盾普遍存在于城乡地区。广大农村地区建设活动日渐频繁,新农村聚居点建设也渐成趋势,但由于缺乏系统、全面的选址分析,部分新农村聚居点的规划要么仅限于图纸上,要么实施与规划相距甚远,因此针对新农村聚居点选址的研究很有必要性。目前针对农村居民点选址问题的研究主要涉及选址原则、评价体系、影响因素分析等方面,但针对川南浅丘地区新农村聚居点选址的研究非常少,因此本文对隆昌县云顶镇的新农村聚居点选址研究具有积极意义,也非常有必要性。本文的研究内容主要包括新农村聚居点选址评价指标体系构建和云顶镇新农村聚居点选址评价。首先,本文在梳理相关理论、国内外文献、云顶镇基础资料的基础上,选择了相对合理的研究方法及可能影响选址的因素;其次,通过问卷、访谈等方式对云顶镇的7个聚居点及周边地区进行了实地调研,初步建立选址评价指标体系;再次,结合专家意见修改得到最终的评价指标体系;从次,在比较了农民和专家的打分样本数据后选择专家为评价主体,并计算了各项指标的权重系数;然后,提取各项指标的基础数据,利用Arcgis剔除了云顶镇不适宜选址的区域,再分别将16项指标建立图层,转化成栅格数据后利用栅格计算器按权重合并各指标图层,得到云顶镇的选址适宜性分析图;最后,对云顶镇已规划的聚居点进行了选址优劣性分析,总结了云顶镇新农村聚居点在选址方面存在的问题,并对云顶镇以后的新农村聚居点规划提出了选址建议。通过以上研究,本文得到的主要成果有:(1)构建了云顶镇新农村聚居点包括3项一级指标16项二级指标的选址评价指标体系;(2)确定了各指标因子的权重值,其中一级指标权重值差别不大,二级指标中人均年纯收入(0.1010)、搬迁成本(0.0905)、农户可接受程度(0.1119)的权重值较大,而地面高程(0.0266)、人口密度(0.0292)的相对权重较小,其他指标权重比较平均;(3)将云顶镇选址适宜性分为了适宜区、较适宜区、勉强适宜区、较不适宜区和不适宜区5个等级,其中较好的选址区域主要位于镇域北侧经济条件较好的区域;(4)已规划聚居点中大坳田、沙堰、大草坝三个聚居点选址较好,九社、科堂湾聚居点选址一般,丁家凼和黄大湾聚居点均选址在基本农田保护区,选址极其不合理。
[Abstract]:The relationship between man and land is the basic condition of urban and rural construction, and it is also a problem that must be directly faced and discussed in the development of society today. The most direct resource condition of our country is to have more people and less land, and the contradiction between man and land relations exists generally in urban and rural areas. The construction activities of the vast rural areas are becoming more and more frequent, and the construction of new rural settlement sites is becoming a trend. However, due to the lack of a systematic and comprehensive site selection analysis, the planning of some new rural settlements is either limited to drawings or far from the implementation of the plans. Therefore, it is necessary to study the location of new rural settlements. At present, the research on the location of rural residential areas mainly involves the selection principle, evaluation system and analysis of influencing factors, but the research on the location of new rural settlements in shallow hill area of southern Sichuan is very few. Therefore, this paper has positive significance and necessity to study the location of new rural settlements in Yunding Town, Longchang County. The research contents of this paper mainly include the construction of new rural settlement site selection evaluation index system and Yunding town new rural settlement site location evaluation. First of all, on the basis of combing the relevant theories, domestic and foreign literature, and the basic information of Yunding Town, this paper chooses a relatively reasonable research method and the factors that may affect the location of the site. Secondly, through the questionnaire, Interviews and other methods of Yunding Town of 7 settlements and surrounding areas of field research, preliminary establishment of site evaluation index system; again, combined with expert opinions to modify the final evaluation index system; from the second, After comparing the scoring sample data of farmers and experts, the expert is selected as the evaluation subject, and the weight coefficient of each index is calculated. Then, the basic data of each index is extracted, and the unsuitable location area of Yunding Town is eliminated by Arcgis. The 16 indexes are transformed into grid data, and then the grid calculator is used to merge each index layer according to the weight. Finally, the location suitability analysis map of Yunding Town is obtained. This paper analyzes the advantages and disadvantages of the planned settlement sites in Yunding Town, summarizes the problems existing in the location selection of the new rural settlements in Yunding Town, and puts forward some suggestions for the location selection of the new rural settlements after Yunding Town. Through the above research, the main achievements of this paper are as follows: (1) construct the evaluation index system of the location of the new rural settlement in Yunding Town, including 3 first-grade indexes and 16 second-class indexes; (2) determine the weight of each index factor. Among them, the weight value of the first class index is not different, the weight value of per capita net income (0.1010), relocation cost (0.0905), peasant household acceptability (0.1119) in the secondary index is larger, but the relative weight of surface elevation (0.0266) and population density (0.0292) is smaller. (3) the suitability of Yunding Town location is divided into 5 grades: suitable area, more suitable area, barely suitable area, less suitable area and less suitable area. Among them, the better location areas are mainly located in the areas with better economic conditions on the northern side of the town area; (4) the three settlement sites of Zhongda au Tian, Shayan and Dacao Dam are better than those of Jiulongshe and Keitang Bay. Dingjiatang and Huangdawan settlement sites are located in the basic farmland reserve, the location is extremely unreasonable.
