摘　　要：利用景观生态学格局分析方法,将东坡区景观分成耕地、林地、草地、水体、建筑用地和裸地景观六大类。通过遥感影像判读解译,得到上述六类景观基本形状数据。通过计算得到各景观的斑块总面积指数、景观类型所占景观面积的比例指数、斑块数指数、最大斑块指数、平均斑块面积指数、景观破碎化指数、景观优势度指数和多样性指数等景观格局数,初步分析2000年和2007年该区景观格局变化,为经济开发和环境保护提供科学依据和决策支持。By utilizing pattern analytical methods of landscapes ecology, the landscape of Dongpo District can be divided into six themes, such as cultivated land, forest land, grassland, water areas, builded-up landscape and bare-land. Based on interpretation and classification of remotely sensed images, together with other assistant information, some shape data of pattern can be received, then a variety of landscape indices can also be achieved by calculating these shape data including the fractal dimension, landscape diversity index, landscape dominance index, landscape isolation, coefficient of variation to the landscape etc. So the landscape pattern changes also can be achieved by comparing the Dongpo District in 2000 and 2007, then the thesis provide a scientific basis and decision support for economic development and environmental protection.
