中文摘要	利用GIMMS NDVI_(3g)等数据对青海高原地区植被覆盖的空间分布特征、自相关特征、聚集规律以及分异特征进行研究。结果表明,研究区3 000m以下主要为荒漠和草甸覆盖,3 000~4 000m主要为草甸、荒漠和草原覆盖,而4 000m以上主要为草甸、草原和高山植被覆盖,高程分异特征显著;研究区植被覆盖从东南向西北方向呈递减趋势,年内总体NDVI在0.11~0.34范围内变化,3 000~4 000m区域的植被覆盖最好;东部及东南部地区的NDVI值具有较高的高值聚集性,西北部地区具有较高的低值聚集性;全局NDVI与经度有明显的正相关关系,与纬度有明显的负相关关系,NDVI分布有明显的水平地带性特征。
英文摘要	This paper studies the spatial distribution,autocorrelation,aggregation rules,and differentiation characteristics of vegetation coverage in Qinghai Plateau using GIMMS NDVI_(3g)and other dataset.The result shows that the features of elevation differentiation in the study area are significant,and the area below 3 000mis covered mainly by deserts and meadows,3 000~4 000mis mainly covered by meadows, deserts,and grasslands,and above 4 000 mis mainly covered by meadows,grasslands,and alpine vegetation.The vegetation coverage shows decreasing trend from southeast to northwest,the overall NDVI varies within the range of 0.11~0.34,and the vegetation coverage in the 3 000~4 000mregion was the best.The NDVI values in the east and southeast regions have a high value clustering,and the northwest regions have a low value clustering.The result also shows that there is a significant positive correlation between NDVI and longitude,there is a significant negative correlation with latitude,and the NDVI distribution has obvious horizontal zonal characteristics.
