【摘要】：以重庆市涪陵区义和镇为研究对象,从自然因素、经济因素和社会因素3个方面,构建该地区土地利用格局的影响因子体系,运用Logistic回归模型对耕地、园地、林地、交通运输用地、水域及水利设施用地、城镇村及工矿用地等6类用地的利用格局进行拟合分析。研究发现,自然条件是影响义和镇土地利用格局的根本性制约因素,但经济因素和社会因素对土地利用格局的影响作用也逐渐显著;土地利用格局与到居民点的距离、到河流的距离、到道路的距离的回归结果多为负方向,说明距离这些区位要素越近,土地利用的发生比越大,也表明耕作半径对地形复杂地区土地利用格局的影响作用比较显著;到李渡工业园区的距离因子对各类用地格局的影响均不显著,说明其短时间的发展尚未对义和镇的土地利用格局产生影响。
[Abstract]:Taking Yihe Town of Fuling District of Chongqing as the research object, this paper constructs the influence factor system of land use pattern in this area from three aspects of natural factor, economic factor and social factor, and applies Logistic regression model to farmland, garden land and woodland. The utilization patterns of six kinds of land, such as transportation land, water area and water conservancy facility land, town and village land and industrial and mining land, were fitted and analyzed. It is found that natural conditions are the fundamental restricting factors to the land use pattern in Yihe Town, but the influence of economic and social factors on the land use pattern is gradually significant, and the distance between the land use pattern and the residential area, The distance to the river and the distance to the road are mostly in negative direction, which means that the closer to these location elements, the greater the ratio of land use to land use. It also shows that the influence of tillage radius on land use pattern in complex terrain area is significant, and that the distance factor to Lidu Industrial Park has no significant effect on all kinds of land use patterns. It shows that its short-term development has not yet had an impact on the land use pattern of Yihe Town.
