中文摘要: 植被覆盖度是评价气候变化影响与生态系统状况的重要指标.基于MODIS-NDVI数据对吉林省20012010年的植被覆盖度进行估算,并分析其时空动态变化.结果表明: 1)近10年吉林省东部的植被覆盖情况明显好于西部,但西部的植被覆盖情况在10年中有显著变好的趋势.根据人口重心原理可知,吉林省10年的植被覆盖度重心有向高纬度、低经度方向移动的趋势;2)不同的土地利用类型的植被覆盖度差异很大,林地、农田和草地的植被覆盖度依次减小;3)分析气象站点10年期间的降雨数据后发现,处在东部的延吉站降雨量与植被覆盖度呈正相关,处在中西部的长春、四平及前郭尔罗斯3个气象站点的降雨量与植被覆盖度均成负相关.
英文摘要: The fractional vegetation cover (FVC) is an important indicator for evaluation of impacts of climate change and the ecosystem conditions. In this study,FVC and its tempspatial variation from 2001 to 2010 in Jilin province was deeply examined on the basis of MODIS-NDVI data. The results are the following: 1) FVC in the eastern region was better than in the western region,but FVC in the western region became better and better. According to the principle of population center,the center of gravity for FVC in Jilin province had the trend of shifting to high latitudes and low longitude. 2) The FVC were greatly different for different land use types. The FVC for the woodland,farmland,and grassland decreased in turn; 3) After analyzing the data of the meteorological stations in Changchun, Siping, QianGorlos, and Yanji, we found that the precipitation and the FVC in the eastern regions are positively related and the precipitation and the FVC in the center and western regions are negatively related.
