摘要/Abstract

摘要： 植被变化对区域生态系统稳定和生态环境变化有着重要的影响。基于MOD13A3数据，建立了2000-2015年祁连山地区植被覆盖时空数据集，结合DEM和土地覆盖分类数据，分析了祁连山地区植被时空分布格局及变化特征，并利用同期气象数据探讨其对气候变化的响应。结果表明：祁连山植被呈东多西少的分布格局，其空间分布与降水空间分布一致；2000年以来祁连山地区灌丛和高寒稀疏草甸先增后减，山地森林草原和高寒草甸增加；整体上祁连山植被覆盖有转好趋势，这与区域暖湿化有关。

Abstract: Variations of vegetation play an important influence on regional ecosystem stability and ecological environment. In this paper, the MOD13A3 data were used to investigate the vegetation coverage in the Qilian Mountains during 2000-2015. The digital elevation model (DEM) and land cover classification were also applied to divide the interval altitude and different lands use to further discuss spatiotemporal pattern and variations of vegetation coverage, and then to analyze the climatic response by using meteorological data. The results presented that the vegetation coverage pattern in the Qilian Mountains is more in the east and less in the west, consistent with the spatial distribution of precipitation. The bush wood and alpine sparse meadow had grown better from 2000 through 2008, after then, they had gone worse. Meanwhile, alpine sylvosteppe and alpine meadow had become better. The whole vegetation coverage in the Qilian Mountains is increasing, which might be caused by the climatic changing to warmer and wetting.

Key words: NDVI, Qilian Mountains, distribution pattern, spatial-temporal variation
