中文摘要: 植被覆盖的时空变化可以反映气候变动的规律和趋势,是全球能量循环和物质流动的组成部分,可作为生态环境演变研究的重要方面。为研究河北省近些年植被NDVI变化和分布的情况,在SPOT-VGT数据的基础上,将研究区划分为坝上高原、燕山太行山山地和河北平原3个生态区,结合研究区的土地覆盖数据,利用最大合成法和均值法获取研究区内各时间点和各土地覆盖类型的NDVI值,通过趋势分析法对研究区NDVI时序变化趋势进行探析,由此对整个研究区和各生态分区NDVI时空变化与分布特征进行综合分析。结果表明:(1)河北省近11年NDVI整体呈上升趋势,植被覆盖总改善面积大于总退化面积,改善面积主要分布在坝上高原和燕山太行山山地部分地区,退化面积主要分布在河北平原部分地区。(2)河北省三生态区不同土地覆盖类型上的NDVI变化特征不尽相同,针对各个土地覆盖类型NDVI的变化特征提出了改善不同生态分区植被NDVI的方法和建议。
英文摘要: The changes of vegetation cover could reflect the patterns and trends of climate change, which was a part of the global material circulation and energy flow and was used as an important aspect of the evolution of ecological environment. In order to study the recent change and distribution about NDVI in Hebei Province, this article took SPOT-VGT and land cover data as the foremost information source, divided the study area into Bashang plateau, Yanshan & Taihang Mountains, Hebei Plain. Spatial and temporal change of vegetation cover in every ecological zone was analyzed using the methods of the maximum synthesis, average method and trend analysis. The results showed: (1) Nearly 11 years, NDVI showed an overall rising trend in Hebei Province, and the vegetational cover area was larger than the degraded area. The improvement districts were mainly distributed in some areas of Bashang Plateau and Yanshan & Taihang Mountains, and the degraded area mainly distributed in some parts of Hebei Plain. (2) The NDVI variation was different from one type of land cover to another in every ecological zone. Considering the NDVI variation, some recommendations could be made to improve the NDVI method and advice in different ecological area.
