【摘要】 晋陕蒙接壤地区属鄂尔多斯沙质高原与黄土高原的过渡带，是干旱和半干旱地区。本研究以晋陕蒙接壤地区11个县(市、旗)为空间单元，进行土地利用与土地覆被变化研究。采用遥感图像(TM)和统计资料两种数据源。应用1986年与2000年两期TM遥感影像判图制图，编制两期同一比例尺下的晋陕蒙接壤地区土地利用现状图。在ARC／INFO的支持下，建立空间信息库，套合叠加，获取该地区土地利用类型动态转移数据矩阵，揭示该地区14年来土地利用与土地覆被的空间分布规律及其变化特征。 通过运用景观生态学的基本理论与方法，选取分维数、分离度和景观优势度等指标和特征参数，对该区脆弱环境的景观格局进行了定量化的分析。通过对自然、经济、社会及人口驱动因子与土地利用及土地覆被变化辨识的相关性统计分析，辨识出了研究区土地利用与土地覆被变化的主要驱动力和驱动力机制。 应用Markov链模型来预测分析研究区未来土地利用格局的变化趋势。最后提出了促进本研究区域未来可持续发展的对策。更多还原

【Abstract】 The adjacent area of Jin-Shan-Meng is the arid and semi-arid area, located at the buffering area between sandy Eroded Plateau and Loess Plateau, including 11 counties. It is characterized with poor natural conditions and weakened wreaked ecological systems.This study uses the GIS tools to analyze the land use and cover change (LUCC) in the past 14 years, based on the remote sensing information and statistic data. By interpretation of 1986’s and 2000’s TM images, two kinds of land use types map in Jin-Shan-Meng adjacent area were compiled. The dynamic transfer date matrix of land use types in the given study area was also obtained through developing spatial information database and overlaying the two kinds of vector maps using ARC/INFO software. The preliminary results show that the intensity of land use has been increasing and spatial changes also greatThis study applies the basic theory and method of landscape ecology, fractal dimension, isolation and dominance as index to analyze the landscape pattern of fragile environment in the given study area. The result of the relevance analysis between LUCC and the driving forces in context of natural, economic, social and cultural factors, shows that key driving forces and driving dynamic mechanisms.Additionally, the Marko process are taken to forecast the landscape pattern of the given study area in the future. On such analysis, counter measures for sustainable development for economy and environment are suggested in hope of promoting the sound development of the gived study areas’ economy and environment.更多还原
