采用Logistic回归分析法,以长株潭城市群核心区域为研究区域,结合由遥感与GIS方法得到的地形与社会空间数据,在7个空间尺度上构建建设用地、耕地、林地变化的驱动力模型,探讨土地利用/覆盖变化的尺度效应,并在最佳模拟尺度上定性定量分析区域土地利用/覆盖变化的驱动机制。结果表明:不同尺度模型的拟合优度差异明显,呈现波动变化趋势;当模拟尺度为180 m×180 m时,建设用地、耕地和林地的拟合优度均达到最高。对建设用地变化有重要影响的解释变量是到主要道路的距离、到市区环线的距离、到各级政府的距离;对耕地变化有重要影响的解释变量是高程、到市区环线的距离;对林地变化有重要影响的解释变量是到主要道路的距离、到各级政府的距离、到市区环线的距离。  相似文献

分析和预测城市土地空间结构演变规律,可以为城市产业转型和可持续发展提供决策支持。本文以萍乡市作为研究对象,利用2009—2018年土地利用数据和社会经济指标,分析其土地利用变化特征,并运用主成分分析法得到引起萍乡市土地利用变化的驱动因子。结果表明:2009—2018年,萍乡市建设用地和交通用地面积逐年增加,其中,建设用地面积变化幅度最大,交通用地面积变化速率最大;园林地、草地、耕地、工矿用地、水域和未利用地面积逐年递减,其中园林地和耕地面积减少最大;社会经济因子、人口因子、产业结构因子是引起萍乡市土地利用发生改变的主要驱动因子,人民生活水平的提高和政府管理部门的政策和规划也发挥了重要作用。研究结果将有助于萍乡市科学规划管理土地,发掘城市可持续发展的潜在空间资源,统筹和合理利用土地。  相似文献

市县乡级土地利用总体规划中的土地利用分区应用研究   总被引:1,自引:0,他引:1  
国土资源部51号文对新一轮市县乡级土地利用总体规划编制提出了具体意见,明确要求通过3条界线和4类分区实现对土地利用空间管制的目标。本文以51号文最新要求为依据,结合国发[2007]21号关于主体功能区规划的意见以及国土资源部2008年新“三定”方案中关于编制并组织实施国土规划的相关精神,以新一轮土地利用总体规划编制为核心,通过讨论土地分区相关理论,理清国土空间分区之间的关系,分析各类分区衔接应用的方法和措施,并依此在市县乡这一空间尺度内,对新一轮规划编制与实施中借助土地空间分区实现空间布局引导和结构指标控制的分区目的、强化土地用途管制制度提出了初步建议。  相似文献

This paper reports the results of an exercise on the development and application of a rule-based software program,Combine for integration of thematic information in simplest possible way. The program was used for forest land use planning in a shifting cultivation area in north-east India. The program can integrate 28 thematic information layers with upto 256 classes in each layer using 8-bit data. Additionally the software can be used for many per pixel image processing operations like merging of digitally and visually classified images, merging of a large number of thematic classes into a few wanted ones, density slicing, image thresholding etc. conveniently.  相似文献

The study reported herein deals with the utility of satellite remote sensing techniques for land evaluation for agricultural land use planning. False colour composite of Landsat imagery in the scale of 1:250,000 was visually interpreted for physiography that formed the base for mapping soil and land resources in the field. The small-scale soil map thus prepared has thirteen map units with association of soil families. Soil and land resource units shown on these small-scale maps were evaluated for their suitability for growing sorghum crop by matching the relevant land qualities against the land requirements for sorghum. The land evaluation carried out for growing sorghum crop in the study area revealed that about 38.6 per cent is highly suitable (S1), 31.5 per cent moderately suitable (S2) and 24.5 per cent marginally suitable (S3). An area of about 5.4 per cent is not suitable, of which 3.0 per cent is currently not suitable (N1) and 2.4 per cent permanently not suitable for growing sorghum crop.  相似文献

A Soil and land Use Map of Pohru catchment was prepared through the adoption of a systematic Air Photo-interpretation procedure including selective field studies in such a manner that the ten delineated mapping units were co-extensive with major Land Resource Areas. Defined in terms of physiography, soil profile, soil erosion and present land use each of the ten units has unique characteristics requiring differential management, which was arrived at through joint field studies by Pedologists who prepared the Map, Foresters, Soil Conservationists, Agronomists. a Horticulturist and an Agricultural Chemist. Stemming from this integrated effort a Land Use Plan for the catchment was drawn up with its major objective as the conservation of Land and Soil Resources leading to a reduction in sediment yields that are now so high as to clog the Jhelum river at the polnt where Pohru river joins it. In respect of four Land Resource areas, the plan prescribes radical readjustments of Land Use such as conversion of Forest Department owned Himalayan Southern slopes to grass lands, change of cropping pattern in Karewa side slopes and conversion of the northern and southern Himalayan footslopes now under cultivation into orchards. The areal extents of the different Land Resource Areas as also the cost of implementing the conservation recommendations have been furnished for every one of the twentyeight watersheds falling under the eight subcatchments of the Pohru catchment. The total cost of implementing the conservation recommendations approximates to about fifty five million rupees.  相似文献

Land is one of the prime natural resources. A city grows not only by population but also by changes in spatial dimensions. Urban population growth and urban sprawl induced land use changes and land transformation. The land transformation is a natural process and cannot be stopped but it can be regulated. Many geographical changes at the urban periphery are associated with the transfer of land from rural to urban purpose. There is an urgent need for fast growing areas like Delhi, which can be easily done by high-resolution remote sensing data. Land use/land cover of North West of Delhi has been analyzed for the time period of 1972?C2003. The remote sensing data used in study is Aster image of 2003 with a spatial resolution of 15?m and other data of 1972 Survey of India (SOI) toposheet at the scale of 1:50,000. Supervised digital classification using maximum likelihood classifier was applied for preparing land use/land cover. A change detection model was applied in ERDAS Imagine to find out the land use/land cover during 1972 to 2003. Eight land use classes was identified but main dominated classes were built up and agricultural land. A drastic change has been recorded during 30 years of time i. e. (1972-2003). In 1972, 92.06% of the land was under agricultural practice, which reduced to 64.71% in 2003. This shows 27.35% decrease in agricultural land in three decades. On the other hand built up area was 6.31% in 1972, which increased to 34% in 2003. One of the main cause of this land use change is the population growth due to the migration in the district from small cities and rural areas of Delhi.  相似文献
