摘  要：
以若尔盖县2000,2010,2016年夏季末的3期Landsat卫星影像作为主要数据源,在遥感图像处理软件(ArcGIS 10.2和ENVI 5.3)以及景观分析软件(FRAGSTATS 4.2)的支持下,利用景观生态学理论分析了若尔盖县2000—2016年间景观格局变化特征、各景观类型间转化情况以及景观指数变化特点。研究表明:1)2000—2010年研究区内景观斑块类型之间转化频率较高,主要表现为其他景观类型向草地转化,沼泽和湖泊湿地的面积开始缩减,沙地景观大规模转化为草地; 2)2010—2016年间,景观转移变化的趋势明显降低,沼泽和湖泊湿地的面积有所恢复; 3)总体而言,研究区的基本景观格局未发生明显变化,草地是研究区内优势度最高的景观类型,道路、居民点的面积和异质性都在持续增加。

摘  要：
In this study,3 Landsat satellite images at the end of summer of 2000,2010 and 2016 in Zoige County were taken as the main data source.With the support of remote sensing image processing software(ArcGIS 10.2 and ENVI 5.3)and landscape analysis software(FRAGSTATS 4.2),the characteristics of landscape pattern change,the conversion between various landscape types and landscape index change in Zoige County from 2000 to 2016 were analyzed by using the theory of landscape ecology.The study indicated that,1)from 2000 to 2010,the frequency of transformation between patch types in the study area was relatively high,mainly reflected in the conversion of other landscape types to grassland,the area of marsh and lakes began to shrink,and the landscape like sand and desert became grassland on a large scale.2)From 2010 to 2016,the variation trend of landscape transformation was significantly reduced,and the area of marsh and lakes was restored.3)Overall,the basic landscape pattern of the study area did not change significantly,grassland was the most dominant landscape type in the study area,the area and heterogeneity of roads and residences continued to increase.
