2000-2012年祁连山植被覆盖变化及其与气候因子的相关性

研究祁连山地区植被覆盖变化及其与气候因子的响应关系对这一地区土地利用总体特征以及对区域及全球气候和环境变化都将产生深远的意义。利用2000-2012年美国国家航空航天局提供的MODIS NDVI数据并结合相应的气候资料,通过对逐像元信息的提取和分析,运用均值法、斜率分析法、相关分析法,研究了2000-2012年不同季节祁连山植被覆盖的时空变化及其与气候因子的相关性。结果表明:13 a来祁连山植被覆盖整体上呈增加趋势,其中春季植被改善最为明显,秋季次之;植被覆盖变化在不同季节都存在明显的空间差异;不同季节植被与气温、降水的时滞效应不尽相同;祁连山春季大部分地区NDVI与气温呈显著正相关,夏季NDVI与降水呈显著正相关,秋、冬季NDVI与降水、气温的相关性不明显。     

近15 a黄土高原植被覆盖时空变化及驱动力分析

研究黄土高原地区植被覆盖变化及其驱动因素可以揭示研究区气候变化和人工生态调节过程对植被变化的影响。基于500 m分辨率的MODIS-NDVI数据和同期气象数据,运用均值法、斜率分析法、相关分析法及残差法,分析了2001-2015年黄土高原的植被时空演变变化特征及其驱动因素。结果表明：近15 a黄土高原植被在季度上总体都呈现增加趋势且存在一定差异,夏、秋季植被增加最为明显;黄土高原植被覆盖在空间上呈现自东南向西北递减的分布特征;植被NDVI变化在不同季节上都存在明显的空间差异;黄土高原植被NDVI对气温、降水的响应关系有明显的季节差异,并在空间上与降水的相关性显著,与温度相关性不明显;人类活动对植被覆盖变化有双重影响,其中生态恢复工程是黄土高原中部地区植被覆盖快速增加的重要因素。     

基于生态地理分区的青藏高原植被覆被变化及其对气候变化的响应

基于1982~2006年GIMMS NDVI数据集和地面气象台站观测数据,分析了青藏高原整个区域及各生态地理分区年均NDVI的变化趋势,并通过偏相关分析研究不同生态地理分区植被覆被变化对气温和降水响应的空间分异特征。研究表明:(1)近25年来,高原植被覆盖变化整体上趋于改善;高原东北部、东中部以及西南部湿润半湿润及部分半干旱地区植被趋于改善,植被覆盖较差的北部、西部半干旱和干旱地区呈现退化趋势;(2)高原植被变化与气温变化的相关性明显高于与降水变化的相关性,说明高原植被年际变化对温度变化更为敏感;(3)高原植被年际变化与气温和降水的相关性具有明显的区域差异,植被覆盖中等区域全年月NDVI与气温和降水的相关性最强,相关性由草甸向草原、针叶林逐步减弱,荒漠区相关性最弱。生长季植被覆盖变化与气温的相关性和全年相关性较一致,降水则不同,生长季期间高原大部分地区植被变化与降水相关性不显著。     

1998—2012年黄河流域植被覆盖变化时空分析

利用黄河流域1998—2012年SPOT-NDVI数据及同期119个气象站的降水数据,计算每个像元的NDVI变化趋势,并结合植被降水利用效率来分析近15年来黄河流域植被覆盖的时空变化特征。结果表明：（1） 多年平均的植被指数有明显的空间差异性,随着纬度的增加,NDVI平均值呈降低趋势;（2） 从时间序列来看,黄河流域的植被覆盖呈逐年增加趋势,其中黄河上游NDVI值增长最为缓慢,中游保持稳定增长,下游增长最快;（3） 近15年来黄河流域植被覆盖的改善区域面积大于退化区域,植被恢复明显。最后,结合NDVI变化趋势和植被降水利用效率对上述结果进行了验证。     

基于多源遥感数据集的近30a西北地区植被动态变化研究

基于重构后的AVHRR GIMMS NDVI、MODIS NDVI、GLC 2000数据产品和研究区的128个气象站点的气温、降水数据,利用回归分析、相关性分析法,研究了西北地区近30 a(1984-2013年)以来不同植被NDVI的时空变化及其与气候的相关性。结果表明:(1)研究时段内,西北地区植被NDVI变化整体上呈上升趋势,将整个研究分为两个时段,1984-1997年呈小幅上升趋势,且波动起伏较大,最大值在1993年,最小值出现在1995年;1997-2013年也呈波动上升趋势,且上升趋势大于前一阶段。(2)空间上,西北地区植被NDVI变化存在明显的区域差异,大部分区域植被NDVI变化显著性较弱,昆仑山、塔里木盆地北部、祁连山、青海的中东西部、甘肃东部、陕西北部等地区植被NDVI显著增加;阿尔泰山、天山、伊犁哈萨克自治州等干旱地区植被NDVI下降趋势明显。(3)除甘肃的祁连山、青海东南部、陕西的秦岭等地植被NDVI的变化主要受气温的驱动外,西北地区植被NDVI变化与气温整体上呈弱相关,干旱半干旱地区植被与气温呈负相关;除甘肃南部、祁连山西段和陕西中部等一些年降水量较多以及灌溉农业区或草地以外,西北地区植被与降水呈较强正相关,降水是影响植被变化的主要自然因素;(4)不同植被类型NDVI的变化具有时空差异性,且与气温和降水的相关性不尽相同,与气温由强到弱:耕地灌丛草地沼泽湿地林地;与降水由强到弱:耕地草地灌丛林地沼泽湿地。     

近10年重庆市归一化植被指数变化分析

运用1 km分辨率经过Savitzky-Golay滤波技术平滑处理的SPOT/VGT数据,通过对1998~2007年的归一化植被指数(NDVI)时间序列数据、NDVI与气象因子的关系、10 a来NDVI变化率的空间分布以及NDVI与海拔高度的关系等进行分析,研究重庆市植被变化及空间分布情况。结果表明,重庆市NDVI年变化相对稳定,在空间上变化较大,东北及东南部分地区植被退化,而西部地区NDVI变化率增加,表明植被覆盖有所增多。另外引起NDVI时空变化的原因中,温度远大于降水量,海拔高度也与NDVI有较好的相关性。     

中国西北地区植被覆盖变化驱动因子分析

利用GIMMS/NDVI数据分析了中国西北地区1982-2006年植被覆盖时空变化特征及其驱动因子。近25 a来,中国西北地区年均植被NDVI增速为0.5%/10 a,并存在明显的空间差异。天山、阿尔泰山、祁连山、青海的中东部等地区植被NDVI显著增加;青海南部地区、陕西和宁夏交界地区、甘肃的部分地区以及新疆的塔里木盆地、吐鲁番、塔里木河、托里等地区植被NDVI下降。从不同植被类型来看:林地、草地和耕地的年均NDVI都在提高。研究表明:中国西北地区植被NDVI变化是各种自然和人为影响因素综合作用的结果。自然植被(林地等)变化更大程度上反映了气候变化对植被的影响,而人工植被(耕地等)变化更多体现的是人类活动的作用。不同高程、坡度、坡向上的植被NDVI变化存在较大差异,当海拔超过4 000 m时,植被NDVI增加趋势很小;坡度低于25°的坡地植被NDVI增加主要是由于近年来的植被建设;阳坡植被变化比阴坡活跃,植被改善趋势较强。植被NDVI与气温、降水的年际变化整体上都呈弱的正相关,温度上升使蒸发量增大,促进了土壤的干化,不利于植被生长,并且灌溉农业区的河水灌溉会降低农业植被NDVI和降水的相关程度。农业生产水平和植被生态建设等人类活动对西北地区植被NDVI增加起重要作用。     

近15a陕西省植被时空变化与影响因素分析

利用2000—2014年MODIS/NDVI时间序列数据，采用栅格像元趋势分析、稳定性评价的方法，研究了陕西省近15 a植被的时空变化特征和规律；利用Hurst指数对陕西省植被未来变化趋势进行了预测；并利用相关性分析法分析了NDVI与年均温度和降雨量的关系。结果表明，2000年、2015年陕西省NDVI均值分别为0.4273、0.4942， 15 a来增加了0.067，增长了16.0%，其中陕北地区NDVI增加明显，关中部分地区出现负增长，陕南地区NDVI总体依旧维持在较高水平。陕西省植被变化趋势具有明显的空间差异性，全省植被未变化的占52.0 %，改善部分占44.27 %，退化部分占3.73%，说明15 a间陕西省植被覆盖改善面积大于退化面积，植被状况有所改善；其中陕北地区植被呈明显改善区域面积较大，关中地区植被覆盖面积有所减少，陕南地区植被变化幅度较小。陕西省植被稳定区域占50%以上（0 0.2)，说明15a间陕西省植被较为稳定，变化程度不大；其中陕西省植被最稳定地区主要集中在陕南、延安南部，榆林部分、西安、渭南少部地区变化幅度较大。Hurst指数分析表明陕西省44.54%面积的植被未来有可能面临退化，主要分布在陕北和关中地区的北部，植被未来有可能退化也有可能改善的面积占49.78%，主要分布在延安和陕南地区。陕西省近15 a气温和降水量总体呈增加趋势，增加速率分别为0.48 ℃·(10 a)-1和69.5 mm ( a)-1；相关性分析结果表明，年均降雨量是影响NDVI的主要气象因子，同时陕西省植被变化也受到了退耕还林还草、防沙治沙、生态政治等人为因素的影响。     

黄河流域NDVI时空变化及其与降水/径流关系

NDVI是表征区域植被覆盖的重要指标。本文把黄河流域划分为 16个区域 ,利用Pathfinder (探路者 )的AVHRR NDVI资料 ,得到各区域 1982～ 1998年NDVI统计序列 ,详细分析了各区域NDVI时空变化特征。研究表明 ,17年来黄河流域各分区年平均NDVI都呈增加趋势 ,说明植被覆盖增加 ,生态环境好转 ,但是 8月份龙羊峡以上和兰河干流区间NDVI则有所下降 ,生态环境有局部恶化趋势。最后研究各区域NDVI与降水、径流和径流系数的年内、年际相关关系 ,结果表明 :从年内变化看 ,黄河流域各区域NDVI变化与降水、径流变化呈明显的正相关 ;从年际变化看 ,黄河流域各区域NDVI波动趋势与降水具有一定的相关性 ,但与径流、径流系数变化的关系相对复杂 ,不具有明显的相关性     

基于生态分区的内蒙古地区植被覆盖变化及其影响因素研究

基于GIMMS数据和MODIS数据反演1982~2011年内蒙古生长季NDVI,分析内蒙古不同生态区内NDVI变化时空特征,探讨自然和人为因素对NDVI的影响。结果表明:30 a来内蒙古生长季平均NDVI整体呈增加趋势,分布在呼伦贝尔、锡林郭勒典型草原的部分地区NDVI有下降趋势。大部分地区NDVI与年降水量呈显著相关,与温度的相关性不显著;近30 a人类活动对植被NDVI的影响程度逐渐增强,其中人类活动在西辽河平原、大兴安岭南端草原区以及华北山地落叶阔叶林区促进植被生长,在内蒙古东北部草原区抑制植被生长。

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.
