| 摘 要： | 以1989年6月、1999年9月的TM遥感影像和2006年6月CBERS(中巴资源卫星)影像为数据源,以Arc-GIS软件为数据分析平台,研究了扎龙国家级自然保护区的景观格局变化特征和景观组分转移。结果表明,扎龙国家级自然保护区景观以沼泽地为主,沼泽地是景观的基质,1989年、1999年和2006年沼泽地的面积分别为1279.3km2、1250.9km2和1238.4km2;该保护区景观破碎化程度加大,其景观格局由简单变为复杂;景观类型的转换以草地转变为耕地、沼泽地转变为耕地和沼泽地转变为盐碱地为主,由此导致该保护区沼泽地面积减少和生物多样性下降。

| Abstract: | Zhalong National Nature Reserve (46°52′N-47°32′N,123°47′E-124°37′E) is located in the west part of Heilongjiang province. Using interpretation of TM images in 1989 and 1999 and CBERS images in 2006, the landscape pattern change in Zhalong National Nature Reserve was analyzed by GIS in this study. The area of the Reserve is 2 100 km~2. The landscape indices such as fragment index, fractal dimension and the diversity indexes, etc. were calculated and analyzed. The results showed that Phragmites australis marsh was the landscape base and it controlled the matter and energy transfer and flow,the areas of marsh were 1 279.3 km~2, 1 250.9 km~2 and 1 238.4 km~2 in 1989, 1999 and 2006 in Zhalong National Nature Reserve, respectively; the landscape was in fragmentation and the biodiversity declined in the Reserve during 1989-2006; the main conversion of the landscape components were grassland into cultivated land, marsh into cultivated land and marsh into saline;the lanscape became complicated in the Reserve. |
