【摘要】：尽管我国国土面积居世界第三位,但由于人口众多,人多地少的现实国情,在很大程度上制约了我们对土地的开发利用建设。伴随着工业化城镇化的快速发展以及人口总量的逐年递增,经济社会发展对土地的需求将越来越大,人地矛盾将日益尖锐。因此,开展后备适宜建设可利用土地资源数量潜力并对其质量进行评价,对于科学掌握后备适宜建设用地潜力、统筹规划不同地区不同行业的用地需求以及完善耕地保护政策,并对于协调人地关系具有积极的现实意义。本文以福州市为研究区,基于GIS技术,以福州市土地利用现状数据库和社会经济数据为基础,以《省级主体功能区划分技术规程》为依据,采用分步式计算模型对福州市各区(县)的后备适宜建设可利用土地资源进行评价。本文主要结论如下:(1)福州市后备宜建设可利用土地资源总面积为1006.38km2,人均后备宜建设可利用土地资源0.2013亩,后备宜建设可利用土地资源较缺乏。各区(县)间后备宜建设可利用土地资源分布不均衡的现象较为明显。从后备宜建设可利用土地资源总面积来看,后备宜建设可利用土地资源总量最多的地区为福清市,面积为283.53km2;后备宜建设可利用土地资源总量最少的地区为台江区,面积为0.11km2。从人均后备宜建设可利用土地资源面积来看,人均面积最多的地区为罗源县,人均0.7831亩;人均面积最少的地区为台江区,人均0.0004亩。(2)从海拔高度来看,低于500m的后备适宜建设可利用土地资源面积为904.17km2,占到福州市后备适宜建设可利用土地资源总面积的89.84%;海拔高度位于500-1000m的后备适宜建设可利用土地资源面积为102.21km2,占到福州市后备适宜建设可利用土地资源总面积的10.16%。(3)从地形坡度来看,福州市后备宜建设可利用土地资源主要分布在 0-20 和 6-150 的地区。分布在 0-20、2-60、6-150、15-250的面积分别 332.93km2、95.37km2、339.25km2、238.83km2,分别占到福州市后备宜建设可利用土地资源总面积的33.08%、9.48%、33.71%、23.73%,海拔高度低于500m的地区中,分布在0-20、2-60、6-150、15-250地区的后备宜建设可利用土地分别占到福州市后备宜建设可利用土地资源的33.02%、8.20%、27.54%、21.09%,因此,福州市后备宜建设可利用土地资源主要分布在海拔高度低于500m的0-20和6-150的地区,占到福州市后备宜建设可利用土地资源总面积的60.56%。(4)福州市后备宜建设可利用土地资源质量分为四等,质量以中低等为主。其中,一等地的面积为155.83km2,占总面积的15.48%;二等地的面积为210.47km2,占总面积的20.91%;三等地的面积为355.21km2,占总面积的35.30%;四等地的面积为284.86km2,占总面积的28.31%。
[Abstract]:Although our country occupies the third place in the world land area, but because of the population is large, the population is large and the land is small, the reality national conditions. With the rapid development of industrialization and urbanization and the increase of the total population year by year, the economic and social development will increase the demand for land. The contradiction between man and land will be more and more acute. Therefore, it is necessary to carry out reserve construction to make use of the potential of land resources and evaluate its quality, so as to grasp the potential of reserve suitable construction land scientifically. Planning the land demand of different areas and different industries as well as improving the cultivated land protection policy, and has a positive practical significance for the coordination of land relations. This paper takes Fuzhou as the research area, based on GIS technology. Based on the database of land use status and social economic data in Fuzhou City, the technical rules for the division of provincial main function areas are taken as the basis. The paper evaluates the available land resources in every district (county) of Fuzhou by using the stepwise calculation model. The main conclusions of this paper are as follows: 1). The total area of available land resources for reserve construction in Fuzhou is 1006.38 km ~ 2. Per capita reserve suitable for construction of usable land resources 0.2013 mu. It is obvious that the distribution of reserve suitable construction and usable land resources is not balanced among different districts (counties). The total area of reserve suitable construction and usable land resources is seen from the point of view of the total area of reserve suitable construction and usable land resources. Fuqing City has the largest amount of available land resources in reserve construction, with an area of 283.53km2; The area with the least amount of available land resources is Taijiang District with an area of 0.11km2. According to the area of available land resources per capita, the area with the largest per capita area is Luoyuan County. Per capita 0.7831 mu; The area with the least per capita area is Taijiang District, 0.0004 mu per capita. (2) from the altitude, the area of available land resources for reserve construction below 500m is 904.17km2. It accounts for 89.84% of the total area of available land resources in Fuzhou. The area of available land resources is 102.21 km ~ 2 when the altitude is between 500m ~ 1000m. It accounts for 10.16% of the total area of available land resources in Fuzhou.) from the angle of topographic slope. The available land resources are mainly distributed in 0-20 and 6-150 areas in Fuzhou. The area of 15-250 was 332.93 km ~ (2) ~ 95.37 km ~ (2) ~ (2) ~ 339.25 km ~ (2) ~ (2) ~ 238.83 km ~ 2 respectively. It accounts for 33.08% of the total land resources available for reserve construction in Fuzhou City, respectively, in the areas with an altitude of less than 500m. The land available for reserve construction in 0-20 ~ (2-60) ~ (60) ~ (6) -150 ~ (0-250) area accounts for 33.02% of the available land resources in Fuzhou City, respectively. Therefore, the available land resources are mainly distributed in 0-20 and 6-150 areas with altitude below 500m. The quality of the available land resources in Fuzhou is divided into four classes, the quality of which is mainly of the middle and low grade. The area of the first class land is 155.83 km ~ 2, accounting for 15.48% of the total area; The area of the second class land is 210.47 km2, accounting for 20.91% of the total area; The area of the third class land is 355.21km2, which accounts for 35.30km2 of the total area. The area of the fourth class land is 284.86 km2, accounting for 28.31% of the total area.
