【摘要】:人地關系是城鄉(xiāng)建設的基礎條件,也是當今社會發(fā)展必須直面和探討的問題,,人多地少是我國目前最直接的資源狀況,人地關系矛盾普遍存在于城鄉(xiāng)地區(qū)。廣大農(nóng)村地區(qū)建設活動日漸頻繁,新農(nóng)村聚居點建設也漸成趨勢,但由于缺乏系統(tǒng)、全面的選址分析,部分新農(nóng)村聚居點的規(guī)劃要么僅限于圖紙上,要么實施與規(guī)劃相距甚遠,因此針對新農(nóng)村聚居點選址的研究很有必要性。目前針對農(nóng)村居民點選址問題的研究主要涉及選址原則、評價體系、影響因素分析等方面,但針對川南淺丘地區(qū)新農(nóng)村聚居點選址的研究非常少,因此本文對隆昌縣云頂鎮(zhèn)的新農(nóng)村聚居點選址研究具有積極意義,也非常有必要性。本文的研究內(nèi)容主要包括新農(nóng)村聚居點選址評價指標體系構建和云頂鎮(zhèn)新農(nóng)村聚居點選址評價。首先,本文在梳理相關理論、國內(nèi)外文獻、云頂鎮(zhèn)基礎資料的基礎上,選擇了相對合理的研究方法及可能影響選址的因素;其次,通過問卷、訪談等方式對云頂鎮(zhèn)的7個聚居點及周邊地區(qū)進行了實地調(diào)研,初步建立選址評價指標體系;再次,結合專家意見修改得到最終的評價指標體系;從次,在比較了農(nóng)民和專家的打分樣本數(shù)據(jù)后選擇專家為評價主體,并計算了各項指標的權重系數(shù);然后,提取各項指標的基礎數(shù)據(jù),利用Arcgis剔除了云頂鎮(zhèn)不適宜選址的區(qū)域,再分別將16項指標建立圖層,轉化成柵格數(shù)據(jù)后利用柵格計算器按權重合并各指標圖層,得到云頂鎮(zhèn)的選址適宜性分析圖;最后,對云頂鎮(zhèn)已規(guī)劃的聚居點進行了選址優(yōu)劣性分析,總結了云頂鎮(zhèn)新農(nóng)村聚居點在選址方面存在的問題,并對云頂鎮(zhèn)以后的新農(nóng)村聚居點規(guī)劃提出了選址建議。通過以上研究,本文得到的主要成果有:(1)構建了云頂鎮(zhèn)新農(nóng)村聚居點包括3項一級指標16項二級指標的選址評價指標體系;(2)確定了各指標因子的權重值,其中一級指標權重值差別不大,二級指標中人均年純收入(0.1010)、搬遷成本(0.0905)、農(nóng)戶可接受程度(0.1119)的權重值較大,而地面高程(0.0266)、人口密度(0.0292)的相對權重較小,其他指標權重比較平均;(3)將云頂鎮(zhèn)選址適宜性分為了適宜區(qū)、較適宜區(qū)、勉強適宜區(qū)、較不適宜區(qū)和不適宜區(qū)5個等級,其中較好的選址區(qū)域主要位于鎮(zhèn)域北側經(jīng)濟條件較好的區(qū)域;(4)已規(guī)劃聚居點中大坳田、沙堰、大草壩三個聚居點選址較好,九社、科堂灣聚居點選址一般,丁家凼和黃大灣聚居點均選址在基本農(nóng)田保護區(qū),選址極其不合理。
[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.
