2000—2020年南非海岸带土地开发利用强度时空变化研究

以南非海岸带为研究区域，利用2000、2010和2020年3期TM、OLI遥感影像提取6类土地利用类型数据，基于土地利用转移矩阵、土地利用类型动态度及土地利用开发强度模型，分析了南非海岸带2000—2020年土地开发利用的结构、程度以及时空变化特征。结果表明（：1）研究期间南非海岸带土地利用类型变化方式主要以草地萎缩和林地扩张为主，其次是未利用地和建设用地扩张，最后是耕地和水体萎缩（；2）土地利用变化过程中，草地与林地相互转化、耕地与草地之间的相互转化是土地变化的主要类型；（3）南非海岸带土地利用开发强度呈现空间聚集状态，形成了以开普敦、伊丽莎白港、东伦敦和德班等为中心的高聚集地区。20年间，南非海岸带土地的开发利用强度整体变化不明显，但2010—2020年以来强度呈现下降的趋势。     

基于土地利用变化的盐城海岸带生态风险评价

在GIS和RS技术支持下,以行政区划为评价单元,从景观结构角度构建生态风险评价模型,借助地统计分析及空间自相关分析方法,对盐城海岸带地区2000-2010年景观生态风险的时空分异特征进行定量评价。结果表明：2000-2010年,盐城海岸带地区整体生态环境质量有所下降。10年间,研究区生态风险平均值从0.35增长至0.39,高等级生态风险区不断增加。土地利用生态风险程度整体空间分异性不断增加,局部呈现高—高聚集和低—低聚集。较高风险区和高风险区主要分布于射阳县、大丰市大丰港以北的沿海区域以及东台弶港附近,其原因主要是随着沿海开发的推进,临港产业和临海城镇的发展,海岸带土地利用变化加剧,沿海地区生态系统稳定性被破坏。     

不同海岸地貌背景下的南海周边岸带35年建设用地扩张分析

通过提取1975年与2010年左右南海海岸带建设用地信息,并对南海海岸带区域进行地貌分区,分析了不同类型海岸带35年建设用地扩张空间格局.结果表明:① 华南大陆和马来半岛建设用地扩张普遍快,中南半岛扩张程度中等,苏门答腊岛,加里曼丹岛和菲律宾群岛除马尼拉湾外普遍扩张程度慢.② 不同海岸地貌因自然资源条件,开发难易程度,腹地大小不同,其建设用地扩张程度差异显著.三角洲平原岸和河口平原岸因水运条件好,腹地广,建设用地扩张普遍显著,台地岸和沙坝--潟湖平原岸因适宜建中小型港口,扩张较为显著,海湾平原岸与山地岸则因平原面积小,开发潜力有限,建设用地扩张普遍不大,平直沙堤平原岸因腹地小,水运不发达而扩张甚微.③ 不同类型海岸带开发模式各异.三角洲平原岸和河口平原岸建设用地空间形态多样化,山地岸,台地岸,海湾平原岸以团块状或条带状为主,沙坝--潟湖平原岸以团块状与星状为主,平直沙堤平原岸多呈条带状,线状或点状分布.     

曾昭璇先生对南海地理研究的重要贡献

曾昭璇先生是中国著名的地理学家,地貌学家和教育家.他在学术生涯的不同阶段对地貌学,自然地理学,历史地理学,人类地理学等学科领域均有积极的探索,他对南海地理问题的研究贯穿他的一生,为中国南海地理研究作出重要贡献.他深入研究南海海岸地貌,珊瑚礁地貌,主张采用"地形类型分析法"划分海岸类型,将中国海岸类型划分为山地港湾岸,台地岸与平原岸;他与梁景芬等合著《中国珊瑚礁地貌研究》,系统论述中国珊瑚礁探测史和石珊瑚的种属,生态,地貌特征与发育,并将中国珊瑚礁划分为四大区,六种地貌类型;他完善了珊瑚礁地貌土地名分类,根据《更路簿》划分南海珊瑚岛礁分布区,绘制珊瑚岛礁探测图;他利用历史文献资料考证"石塘"等南海诸岛古地名;他从地质学与地貌学角度论证南海诸岛与中国大陆的陆缘关系,还利用历史地理与地方志等资料佐证了南海诸岛自古以来就是中国的固有领土.     

南海北部大陆架残留风成沙与海岸带古风成沙的对比及关系研究

广泛分布于南海北部大陆架的残留风成沙,在形态、粒度、石英沙粒表面微结构、矿物组成及浅地层剖面等方面总体上具备风成沉积特征。同时,南海北部沙质海岸多处发育的晚更新世古风成沙,在粒度、沉积构造与结构等方面亦有明显的风成沉积特征。二者构成的风沙地貌体发育具有同期性、形态有相似性、空间分布有大陆架向海岸带延伸的连续性。由此表明,南海北部大陆架与毗邻沙质海岸的沙源有同源性,沉积环境有类比性。据此可以认为,南海北部大陆架残留风成沙与海岸带古风成沙为近源沉积成因系列,二者为同期同相连续性沉积。     

龙口市海岸带土地利用动态变化分析

利用多期遥感数据,采用目视解译和人机交互计算机分类技术提取1984至2004年间龙口市海岸带土地利用信息,从土地利用总量变化、土地利用变化速度、土地利用类型之间的相互转化、土地利用类型变化的海岸区位效应等方面分析龙口市海岸带动态变化特点。研究结果表明,20年间龙口市海岸带一半以上的土地类型发生了变化,变化速度逐年增加,后期明显大于前期;转化方向上主要表现在耕地向园地的转化,其次是耕地、园地、林地向建设用地的转化;变化的区位特征是距海越近,海岸带特征地类的变化越明显,反之,距海越远,内陆土地利用变化的特点表现得越突出。     

区位和管理政策对海岸带土地利用变化的影响--以昌黎黄金海岸地区为例

本文在RS和GIS支持下研究了河北昌黎黄金海岸地区1985年至2000年的土地利用变化格局及其影响因子。该区域的海岸区位对海岸带土地利用变化具有重要影响作用,近岸带变化较剧烈,远岸带变化较小,且具有不同的变化特点。海岸带管理政策对土地利用变化的程度和特征存在重要影响,开发区土地利用变化较剧烈,其变化类型受开发方式及其目标影响;保护区主要是大片沙丘转变为林地和草地。     

海岸带土地利用适宜性评价——以杭州湾南岸为例

位于海域—陆域系统交叉和相互作用的海岸带,其土地利用受到自然和人文的多因素共同影响.进行海岸带土地利用适宜性评价对于经济发展迅速的海岸带土地资源的合理配置和开发利用具有重要意义.以2010年杭州湾南岸土地利用数据为基础,利用LandUSEM模型,依据土地利用类型与评价因素不同等级组合的频繁度进行土地利用适宜性评价,计算不同土地利用单因子适宜度及综合适宜度.结果表明:①中等适宜以上占总区域的73.15％,近四分之一位于临界适宜及以下.这说明杭州湾南岸土地利用适宜性较好,各适宜性等级分异情况明显.②杭州湾南岸土地利用适宜性具有较明显的空间分布特点,且余姚、慈溪岸段适宜性情况较镇海岸段好.镇海岸段的中等适宜与非常适宜区面积比例大于余姚和慈溪岸段,临界适宜以上区域面积远小于余姚和慈溪岸段,这与当地的工业结构有关.③各土地利用类型开发程度较适宜,96.45％的城乡建设用地处于临界适宜以上,其中临界适宜占70.91％;89.31％的滩涂用地位于临界适宜以上,且80.72％为非常适宜,可开发潜力大,可将滩涂用地适当适时地转化为农用地或城乡建设用地,以满足区域内经济发展的需求用地.     

东海区大陆海岸带高强度开发的时空特征及驱动机制

东海区大陆海岸带作为中国海洋经济发展的前沿阵地,具有重要的战略地位。探究海岸带高强度开发的时空变化特征及驱动因素有助于揭示海岸带开发强度演变过程与规律,推动海岸带资源环境与社会经济可持续和高质量发展。故文章以东海区大陆海岸带为研究对象,利用1990—2020年7期海岸线与土地利用数据,揭示东海区大陆海岸线、海岸带土地利用的开发利用强度特征,通过地理探测器方法探究海岸带高强度开发的驱动因素。结果表明：(1)东海区大陆海岸带岸线平均移动速率为32.34 m/a,北部区域海岸线平均移动速率（43.54 m/a）大于南部（20.23 m/a）。杭州湾南岸区域在多个时期内海岸线平均移动速率最快,厦门-漳州区域的海岸线平均移动速率较慢。在空间分布上,海岸线变迁较为剧烈的区域主要集中在河口、海湾以及城市等级较高的沿海区域。(2)耕地、林地、草地、水域、海域等面积不断减少,城镇建设及工矿用地面积不断增加。海岸带南部与北部的土地开发强度整体较高,中部区域土地开发强度较弱。(3)自然因素奠定了东海区大陆海岸带土地利用开发强度的宏观格局,社会经济要素起着重要推动作用。     

海岸带的空间功能分区与管制方法——以宁波市为例

海岸带空间资源的合理开发和利用关系到海洋经济发展质量和优质资源利用效率,成为影响沿海城市区域可持续发展的重要内容。根据区域自然、经济、社会特征,运用相关分区方法,划分海岸线和海岸带开发与保护的适宜性空间,获取较高的空间资源配置效率,成为地理学研究关注的热点。大部分学者从经济和生态两个方面要素构建指标体系,并对分区方法进行了有益探索和尝试,但是由于海岸带具有自然地理的特殊性,所以在指标选择上有较大不同。以宁波海岸带为例,讨论海岸线及海岸带的空间区划指标体系选择和方法应用问题。在借鉴已有区划方法的基础上,重点讨论评价单元划分、评价指标选择与处理等技术方法,在评价海岸线开发适宜基础上,做进一步的海岸带空间功能分区,将宁波市海岸带空间划分为生态空间、生产空间和生活空间,并结合宁波市空间开发现状,提出不同类型区域空间布局调整引导方向和管制要求。
