| 摘 要： | 采用2000年贵州省毕节市的TM/ETM卫星影像数据,依据GIS软件对毕节市岩溶山区乡村景观格局特征进行了分析,结果表明:毕节市的农村景观分布差异性比较大,景观的破碎程度较高,农业景观的完整性较差,景观除了聚落景观的分维数较低外,其他农村景观的分维数比较高.其农村景观的斑块形状极不规则,形状无规律性.

| Abstract: | The TM/ETM satellite image data of Bijie city was analyzed by GIS software to study its landscape structure characteristics.The results showed that there was great difference in rural landscape distribution,the landscape fragmentary degree was higher,the integrity of agricultural landscape was poor and the fractal dimension of other rural landscape was higher except lower fractal dimension of village landscape in Bijie city.Therefore,the stripe shape of rural landscape is very irregular and irregularity in ... |
