1东洞庭湿地植被格局变化及其影响因素显示文摘东洞庭湖(也称东洞庭)湿地植被格局的变化特征及其影响因素的分析是该地区湿地植被保护与恢复策略制定的基础。基于美国陆地资源卫星Landsat TM/ETM+数据,应用决策树分类法分别提取东洞庭湖1999年、2002年、2006年三个时期湿地景观信息,通过转移矩阵法和质心迁移法对植被的时空演变分析。结果表明:(1)1993~2002年东洞庭湖芦苇、林地、苔草滩地面积均有所增加,芦苇增长速度最快,年均增长面积为28.93km2;2002~2006年林地面积迅速增加,年均增长面积为29.655km2,苔草面积有所减少,芦苇面积保持基本稳定;(2)东洞庭湖湿地植被质心呈现从林地—芦苇—苔草逐层靠近湖心的分布特点,1993~2006年三种植被类型的质心均不断向湖心迁移,其中以林地与芦苇的变迁更为显著。雷璇 杨波 蒋卫国 杨一鹏 Claudia Kuenzer 陈强 2012地理研究2012,31,3:43
2东洞庭湖湿地生态系统健康状态与水位关系研究显示文摘基于CBERS卫星遥感影像数据,以东洞庭湖国家级自然保护区为研究区,通过光谱特征分析建立决策树分类模型,提取东洞庭湖湿地的地物类型。以生态系统健康理论为基础,依据东洞庭湖湿地的特点,综合湿地生产力、组织结构、弹性和功能4个方面,建立湿地生态系统健康状态评价指标体系和评价模型,利用GIS技术,分析东洞庭湖湿地在2000-2006年10个时相的生态系统健康状态。结合城陵矶水文站的水位数据,探讨了东洞庭湖湿地健康状态与城陵矶水位之间的相关性,并利用2007年两个时相的数据进行检验。研究结果表明:东洞庭湖湿地健康状态与城陵矶水位之间存在着较大的相关性,当城陵矶水位达到30m左右时,东洞庭湖湿地健康状态达到最佳值。杨波 廖丹霞 李京 蒋卫国 Claudia Kuenzer 周斌 2014长江流域资源与环境2014,23,8:10
