【摘要】：為增強農村居民點地質環(huán)境安全布局認識,科學推動農村建設用地可持續(xù)、健康發(fā)展。以云南省盈江縣為研究區(qū)域,選擇坡度、線性構造等評價指標,用Logistic回歸模型對研究區(qū)進行了地質災害危險性區(qū)劃,其中為了統(tǒng)一評價單元,通過ArcGIS建立魚網將相關地理信息數據網格化。再根據地質災害危險性區(qū)劃結果對現狀農村居民點布局進行相關分析和研究。結果表明:盈江縣地質災害區(qū)劃分區(qū)結果中的中高易發(fā)區(qū)占到全縣總面積的63.57%,包含全縣95.83%的歷史地質災害點;且農村居民點位于地質災害中、高易發(fā)區(qū)的面積占居民點總面積比例達到74.55%,所有鄉(xiāng)鎮(zhèn)都有位于高易發(fā)區(qū)的居民點;基于農村居民點現狀與區(qū)劃結果,將各鄉(xiāng)鎮(zhèn)及其典型村落劃分為3個級別,并針對性地提出"梯度推進"、"內部整改"、"就地城鎮(zhèn)化"3種優(yōu)化方向。
[Abstract]:In order to enhance the understanding of the geological environment safety distribution in rural residential areas, the sustainable and healthy development of rural construction land can be promoted scientifically. Taking Yingjiang County, Yunnan Province as the study area, slope and linear structure were selected, and the geological hazard risk regionalization was carried out with Logistic regression model, in order to unify the evaluation unit. The relevant geographic information data is gridded through the establishment of fish net by ArcGIS. Based on the results of geological hazard zoning, the distribution of rural residential areas is analyzed and studied. The results show that the middle and high risk areas account for 63.57% of the total area of the whole county, including 95.83% of the historical geological hazards in Yingjiang County, and the rural residential areas are located in the geological disasters. The proportion of the area of high-susceptible areas to the total area of residential areas reached 74.555.All townships had settlements located in high-susceptible areas, and based on the present situation of rural settlements and the results of regionalization, the villages and towns and their typical villages were divided into three levels. It also puts forward three optimization directions: "gradient advance", "internal rectification" and "local urbanization".
