元阳哈尼梯田及周边土地利用格局的时空变化分析

以哈尼梯田所在之元阳县为例,应用遥感和GIS方法,首次对该区域1974年、1992年和2000年3个时期的土地利用变化及其特点进行了分析.结果表明:(1) 从1974年至2000年,元阳县土地利用结构变化不大,均以有林地和灌木林为主,二者始终占元阳县总面积的50%以上.其次为水田和旱地,分别占元阳县总面积的15%和20%左右,其他土地利用类型如园地和未利用地所占比例较小.(2)土地利用总体来说,有林地、水田、旱地和未利用地呈现减少趋势;灌木林、荒草地和园地呈增长趋势.(3)从1974年到2000年这27年问不同土地利用类型的相互转化比较复杂,主要发生在有林地、灌木林和荒草地及水田和旱地之间,最显著的演变过程有旱地-水田、旱地-荒草地、灌木林-有林地、有林地-灌木林、灌木林-园地、灌木林-未利用地.(4)政策和经济因素可能是造成元阳县土地利用变化的主要原因.     

龙川江流域土地利用格局变化与趋势预测研究

以龙川江流域为研究对象,在遥感和GIS技术的支持下,应用1988年与1999年两期TM遥感影像解译制图,编制两期土地利用现状图。在ARC/INFO下,建立空间信息库,进行叠加分析,获取该流域土地利用类型动态转移数据矩阵,揭示该流域11年来土地利用空间分布规律及其变化特征。同时,应用Markov链模型对未来土地利用格局趋势进行预测分析,得出有林地、水域、水田、居民地在逐年增加,旱地、荒草地、灌木林逐年减少的结论,从而为调控该流域土地利用结构和方式,改善其生态环境状况提供依据。     

西双版纳土地利用/覆盖格局的热环境效应研究

利用Landsat TM/ETM＋数据的热红外波段,通过单通道算法,反演了中国热带西双版纳地区的地表温度,并对西双版纳地表温度演变的规律进行了分析,结果显示：（1）研究期间,西双版纳土地利用/覆盖发生了剧烈变化,有林地面积不断减少,旱地、灌木林、茶园与橡胶园面积不断增加;（2）旱地、荒草地、茶园、建设用地的地表真实温度的平均值较高,水体和有林地的平均温度较低;（3）旱地、灌木林、有林地、荒草地和橡胶园对区域的热效应贡献较大,水体、水浇地、建设用地、滩涂和水体的热效应贡献较小;有林地的热单元权重有不断减少的趋势,灌木林与旱地的热单元权重有不断增加的趋势;（4）西双版纳土地利用/覆盖的剧烈变化改变了区域地表温度的分布格局,最终可能会导致地方气候变化。需要进一步开展西双版纳地区LUCC—气候—生态系统耦合研究,深入研究区域LUCC特别是橡胶园的时空变化过程及其气候/生态效应、气候变化与LUCC过程的互馈机制,为实现区域可持续发展提供科学依据。     

1960-2010 年贵州省喀斯特山区陡坡土地利用变化

基于GIS 与RS技术, 以贵州省喀斯特山区坡度大于25°的区域为研究对象, 利用1960 年1:50000 地形图、1990 年Landsat TM遥感影像以及2010 年的环境减灾卫星(HJ-1A/1B)影像, 解译获取1960、1990、2010 年3 个时间点的土地利用数据, 并结合贵州省水文地质图、坡度图进行陡坡土地利用变化分析。结果表明:①1960-1990 年的30 年间, 有林地、灌木林、水体呈减少趋势, 其中灌木林减少的最多, 其次是有林地;而草地、建设用地、裸岩和耕地呈持续增长趋势, 其中草地增加的最多, 其次是耕地。②1990-2010 年的20 年间, 灌木林、裸岩、耕地呈减少趋势, 其中耕地减少的最多;而有林地、疏林地、草地、水体呈增长趋势, 其中疏林地增加的最多。③随坡度增加覆盖比例呈降低趋势的土地利用类型为有林地、疏林地、水体、建设用地和耕地;随坡度增加覆盖比例呈增加趋势的土地利用为灌木林、草地和裸岩。     

红水河梯级电站喀斯特库区土地利用及其生态系统服务价值研究

以遥感数据为基础数据源,通过人机交互判读提取广西大化县1988-2006年土地利用类型数据,并分析该区土地利用变化过程及其驱动力。基于中国陆地生态系统单位面积生态服务价值,对各地类生态服务价值重新赋值,估算近18年来研究区生态服务价值变化过程。结果表明:研究区土地利用变化明显,园地、城乡建设用地、裸岩砾石地持续增加,水田、中覆盖荒草地持续减少,旱地、水域先增后减,有林地、灌木林地、低覆盖荒草地先减后增,土地利用变化有明显的区域差异。脆弱生态环境与生存型经济双重驱动、库区建设、移民安置、人口增长、经济发展及国家政策是导致区域人地关系变化的主要动因。研究区土地利用变化对生态服务功能产生了显著影响,生态系统服务价值经历了先增后减的变化过程。调控区域土地利用方式,加大对国家生态政策实施力度,合理控制城镇建设用地的发展,是喀斯特库区持续发展的有效途径。探讨喀斯特地貌单元中土地利用变化的敏感区县,寻找区域土地利用类型的组合,是促进红水河梯级电站喀斯特库区生态服务价值良性发展的关键。     

质变和量变两种维度下新疆山区土地覆盖变化分析

山区是新疆主要的产流区,山区土地覆被变化对新疆经济发展和生态环境安全具有重要意义,但新疆山区的土地利用整体变化情况尚不太清楚。该文基于新疆1∶10万土地覆被类型数据和GIMMS 3 g植被指数数据,综合运用GIS空间分析和月平均、距平和趋势保留预置白处理方法及Mann-Kendall非参数趋势检验方法,提取与分析了新疆三大山区在1990—2010年土地覆盖类型转化和1982—2013年的植被覆盖变化情况,尝试从2个维度分析新疆山区土地覆被变化情况,探讨了植被覆盖的显著变化与土地覆盖类型之间的空间关系。结果表明:1)以土地覆盖类型转化为标志的新疆土地覆被质变情况发生比例很小,99%的土地覆被类型没有发生变化;2)新疆三大山区中均有大于35%的面积植被状态发生了不同方向上的显著变化,阿勒泰山区植被退化30.38%,植被改善4.07%,天山山区植被退化25.27%,植被改善18.26%,昆仑山山区植被退化33.69%,植被改善19.83%;3)发生退化的区域主要分布于人类活动干扰较强的低海拔及山前地区,且主要以草地和稀疏草地为主,阿勒泰山区草地退化面积占到总面积22.18%,天山山区稀疏草地和草地退化面积占到总面积18.88%;昆仑山区植被稀疏草地和草地退化面积占到总面积10.74%。研究结果说明从质变和量变二种角度的分析能够提供对山区土地覆被变化提供更全面的认识,在分析土地覆被变化的生态水文响应时应当给予综合考虑。     

澜沧江流域云南段景观格局分析

流域作为一个特殊的地理生态环境区域,流域景观空间格局状况是进行流域环境资源管理的基础依据。针对澜沧江-湄公河国际河流上游云南段,基于遥感监测所获得的土地覆盖斑块信息,就该地区景观格局进行分析研究。初步结果表明：研究区内景观类型丰富,不同景观类型斑块大小的平均水平,以及斑块密度差异明显;山区早地斑块景观,作为人类驱动影响的直观外在表现,它对本流域山区景观格局具有主导作用。     

基于遥感的山区县域土地覆被变化的驱动力因子和生态环境效应分析--以重庆市忠县为例

在对重庆市忠县区域TM遥感数据进行波谱信息特征实验分析的基础上，建立了土地覆被信息提取的波段组合方案；通过人机交互目视解译和野外数据检验工作，实现利用遥感影像数据对重要生态安全指标因子之一——土地覆被因子的数据提取，并用GIS技术对其时空变化的驱动力因子和生态环境效应进行分析，效果和效率令人非常满意。这不仅在一定程度上解决了中尺度山区县域的土地覆被数据提取与地学分析的技术和方法难题，而且揭示了忠县土地覆被的时空分异特征。这是用常规与传统的技术方法与研究手段难以实现的，也为山区县域生态环境退化评价和生态恢复研究提供了一种新的方法尝试。通过GIS空间分析，揭示了忠县土地覆被和水土流失的时空分异特征。忠县土地覆被动态变化的生态环境效应表现为耕地与林地在“制高地”上(海拔500m以上)的大互换，在平川坝地地区建设用地大量占用优质耕地、林地等土地覆被类型；水土流失发生的坡度分异不明显，主要分布在200～800m间，与坡耕旱地分布密切相关。从总体上，这种变化使区域生态环境系统的功能发生退化。分析发现，忠县土地覆被变化的驱动力主要有：(1)人口压力和经济发展落后是生态环境系统安全状态恶化的社会经济背景因素；(2)对自然资源不合理开发利用是生态环境恶化的直接人为因素；(3)脆弱的生态环境是生态环境恶化的自然环境背景因素。因此，必须采取包括生态移民、生态建设与生态保护等在内的忠县区域生态安全综合调控措施。     

澜沧江流域山区土地覆盖多级遥感分类方法研究

遥感监测土地覆盖是对流域综合开发所引起的有关土地利用状况改变的有效监督控制手段,土地覆盖分类专题信息提取是遥感监测研究的重要内容之一。针对澜沧江流域遥感监测项目,探讨基于地物光谱响应曲线分析提取山区士地覆盖的多级遥感分类方法应用研究。结果表明,基于具体研究区域的典型地物样点光谱响应曲线分析,在多波段间组织设计有关提取具体研究区域土地覆盖类间可分离性明显的算法,分离并提取特定研究区域土地覆盖主要类型,然后再通过结合多级遥感分类方法的应用,可较之单一依靠自动模式识别方法或单一利用目视解译方法获得诸多优越之处和更符合实际的分类效果,是种适合于山区土地覆盖监测的有效、可行而又相对操作简单的方法。     

基于多源遥感数据的北京市通州区土地利用/覆盖与生态环境变化监测研究

土地利用/覆盖与生态环境状况是衡量城市发展水平的重要指标,对于城市建设有着极其重要的作用。该文采用2006-2016年ETM+数据和Sentinel-2A数据,对北京市通州区的土地利用/覆盖和生态环境变化进行了分析,并探讨了其驱动因素。结果表明:2006-2016年北京市通州区耕地显著减少,建筑用地和城市绿化面积增加,水域面积稳中有升;生态环境质量在前5年有一定下降,而在后5年有了明显改善;北京市通州区土地利用/覆盖和生态环境变化的主要原因有政策与重大事件影响、人口与经济发展建设两方面因素,其中政策与重大事件影响在短期内作用显著,而人口与经济发展建设则对土地利用/覆盖和生态环境变化有着长期且复杂的作用。该研究可对北京副中心和京津冀一体化建设提供参考。

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.
