摘要: 运用地理信息系统Arcinfo软件,结合野外调查资料,处理了2005年海拉尔区TM遥感数据,时海拉尔区进行景观类型的划分并绘制了海拉尔区景观类型图,选取了5个度量景观结构的定量指标对其景观结构进行了分析。研究结果表明:海拉尔区可划分出5类一级景观类型、11类二级景观类型、20类三级景观类型;一级景观面积大小依次为:草原(43.34%)〉农田(29.22%)〉湿地(18.37%)〉森林(5.37%)〉人工建筑(3.70%);景观破碎度大小依次为:人工建筑〉湿地〉森林〉草原〉农田景观:森林景观以人工林为主.草原景观以典型草原景观占优势,其中中度和重度退化草原面积占47.79%,连续分布特征明显’农业景观中的大斑块集中分布在典型草原地带.而在草句草原景观中农田呈现小斑块状散布特征.

Abstract: Applying the software of Arcinfo combined with field research to process the TM data in 2002 of Hailaer district,and on the basis of dividing the landscape types and having drawn the map of landscape types,this study selects five quantitative landscape index to analyze the landscape pattern.The results show:Hailaer district can be divided into 5 first-grade landscape types,11 second-grade landscape types,20 third-grade landscape types.The area proportion of the first-class landscape types are: grassland is 43.34%,cropland is 29.22,wetland is 18.37%,forest is 5.37%, artificial architecture is 3.70%. The change trend of the fragmentation of landscape is: artificial architecture〉wetland〉forest〉cropland. Artificial woods is the main part of the forest landscape.the typical grassland is dominating the grassland landscape,among which the medium degradation grassland and the highly intensive degradation grassland are 47.79%,and they have obvious traits of continuous distribute. The big patches are concentrated in typical grassland region in cropland landscape,moreover, croplands are scattered in the meadow.
