高原交通干线对土地利用和景观格局的影响——以兰州至格尔木段为例

运用景观生态学方法和Arc/Info软件，研究1995年至2000年兰州至格尔木铁路沿线的区域土地利用和景观格局变化，分析交通干线（公路和铁路）的影响程度与范围。主要结果如下：（1）东线土地利用和景观格局没有发生显著变化，西线土地利用和景观格局变化较大；（2）东线缓冲带土地利用程度综合指数没有显著变化，西线缓冲带土地利用程度综合指数明显升高。缓冲带综合土地利用动态度的变化反映了交通干线的轴向影响规律；兰州至西宁铁路对土地利用变化的显著影响范围是5km，青藏铁路对土地利用变化的显著影响范围是7km；（3）9个城市缓冲带的土地利用变化分析表明：城市扩展主要发生在1km缓冲带内。     

库伦旗土地利用动态变化研究

面对当前日益严重的"人口、资源与环境"问题,区域土地利用变化的研究越来越受到普遍关注。本文综合分析了2001—2008年库伦旗土地利用变化状况,应用3S技术,结合实地调查,建立解译标志,运用Mapgis6.7进行矢量化、空间分析和数据统计,提取库伦旗2009年土地利用现状数据,从时间和空间两个方面对库伦旗的土地利用动态变化状况进行了分析。最后针对库伦旗土地利用状况,提出合理利用土地资源的建议。     

城市RBD空间结构理论研究——以上海城隍庙和苏州观前街为例

以游憩者比重和旅游企业比重2个变量为指标,对中国比较成熟的2个城市RBD--上海城隍庙和苏州观前街游憩商业区的内部空间结构进行深入研究.研究发现:目前,这2个城市RBD的空间结构都出现比较典型的内部空间结构特征,这些圈层由内到外呈现比较有规律的圈层变化.在对这些特征形成原因分析的基础上,从理论层面提出在特定的假设条件下,城市RBD的圈层结构特征由内到外将会出现核心圈层、边缘圈层和辐射圈层.最后,对该理论在不同情况下的变形进行了推理.     

环渤海地区土地利用的时空变化分析

根据1985和1995年2期TM影像资料，运用遥感影像机助解译方法、地理信息系统空间分析方法以及数理统计方法，全面分析了环渤海地区3省2市1985-1995年间分类土地利用的数量变化和空间变化特征，揭示了该区各类土地利用数量变化的幅度、速度和区域差异以及土地利用空间变化的主要类型、分布特征和区域方向，阐明了该区土地利用变化的区域特点，为土地可持续利用提供有效的决策支持。     

武汉市土地利用覆被变化与生态环境效应研究

利用1996年和2006年两期TM遥感影像解译图获取武汉市土地利用变化数据。基于GIS空间分析与数理统计方法对1996~2006年武汉市土地利用/覆被变化特征进行了定量分析。运用区域生态环境质量指数和区域土地利用变化类型生态贡献率,对研究时段内武汉市土地利用变化的生态环境效应以及导致武汉市生态环境质量变化的土地利用变化类型进行了分析与评价。研究结果表明:① 1996~2006年期间武汉市土地利用变化主要表现为耕地、草地和未利用土地的减少,林地、建设用地和水域面积的增加的态势。② 1996年~2006年武汉市的区域生态环境质量指数从0.451 上升至0.468。生态环境在一定程度上维持着相对平衡,并呈现出一种上升趋势。但生态环境改善和恶化的两种趋势并存。③ 局部地区生态环境呈负向发展,其中城市化引起的空间扩张对区域土地利用/覆被变化产生影响最为深刻。     

基于遥感数据的泉州市土地利用变化分析

本文基于TM遥感图像解译的1985、2000年两期土地利用现状图，借助ArcView3．2软件，统计分析了泉州市1985～2000年间土地利用类型的数量及空间变化特征。结果表明：15年来各类土地利用类型发生了很大变化，综合年均变化率为0．09％；而且类型转化量最大的是耕地转变为城乡、工矿及居民用地，其次是林地与草地类型之间的转化。     

基于RS和GIS的邯郸矿区土地利用变化研究

本文以邯郸矿区为研究对象,利用遥感(RS)和地理信息系统(GIS)对矿区的土地利用变化特征做出了定量分析,通过对三个时相的LandsatTM(1990年、2000年、2010年)影像进行解译,利用的GIS的叠加分析功能,分析邯郸矿区近20年来的土地利用变化情况,为改善农业生产条件和人类生存环境,促进区域经济和生态环境协调发展,推进邯郸矿区的生态修复提供借鉴。     

20世纪90年代无定河流域土地利用的时空变化

本文基于ArcGIS平台,以LandsatTM影像解译得到的三期土地利用数据为基础,结合统计分析工作,对无定河流域20世纪90年代土地利用数量、类型及其变化进行了分析。分析得出,前后2个5年间,无定河流域耕地、林地和未利用土地都是先减少而后稍有增加,草地则是先增加后稍有减少。在10年尺度上土地利用总的动态特征是,耕地与未利用土地面积减少,林地、草地面积增加。前5年无定河流域综合土地利用动态度为0.85%,未利用土地和草地的年变化率较大,耕地与水域年变化率较低。后5年无定河流域综合土地利用动态度为0.3%,林地与未利用土地年变化率较大,耕地与水域变化率较小。最后引入单一土地利用类型相对变化率反映出无定河流域土地利用变化存在明显的区域差异。     

滇西北生态脆弱区土地利用变化及其生态效应 ——以云南省永胜县为例

土地利用/土地覆被变化及其生态环境效应研究是当前地理学全球变化研究的核心内容,而生态系统服务功能则是生态学、生态经济学研究的热点问题。作者利用滇西北生态脆弱区--永胜县1988年、1994年和1999年的TM遥感影像,采用景观生态学的空间格局指数分析研究区近10年来的土地利用动态变化特征,并以生态系统服务功能衡量相应土地利用类型的相对生态价值,评价区域土地利用/土地覆被变化的生态效应,尝试将二者有机结合起来。研究表明,全县景观总体构成表现为景观破碎度较高,斑块数目较多;林地和未利用地一直占很大比重,林地的不断增加与未利用地的迅速减少是研究时段内土地利用变化的突出特征;研究时段内全县土地利用变化带来了较好的生态效应,土地利用生态效益持续提高,并表现出了较大的空间差异。     

中国土地利用时空特征分析

在遥感技术与GIS技术的支持下，对中国近5年来土地利用的时间动态特征和空间动态特征进行了定量分析。具体表现为通过数学建模，利用土地利用动态度模型、土地利用程度模型、垦殖指数模型等对土地利用时空特征进行了分析。研究结果表明：5年间中国土地利用类型发生变化比较大的区域主要分布在东部和北部地区，特别是东北部地区土地利用类型变化比较剧烈，而西部变化相对缓慢；土地利用各类型中面积增加的有耕地、水域、建设用地和未利用地，而林地、草地面积减少；耕地增加的区域位于东北部地区，特别是黑龙江省耕地面积增加最多；林草地以及未利用地的面积变化主要发生在新疆、内蒙和黑龙江等地区，其它地区变化幅度相对较小。

Deserts and Aeolian Desertification in China: Book review and some thoughts

Desertification is a global phenomenon that affects about two billion people. It occurs in arid zones where the annual precipitation is below 400 mm, partic- ularly in the marginal areas of the world＇s largest deserts. It is a result of water and wind erosion, over- grazing, global warm-ing, improper soil cultivation, and increased pressure ot population growth, and it causes degradation of soil and natural and agricultural vegetation. The direct result is less food for people and livestock, which influences pop- ulation and animal husbandry fluctuations. Despite ef- forts to combat and reduce desertification, the affected areas are annually increasing.
