By using the satellite images of 4 periods of time, including the data from Thematic Mapper (TM), Enhanced Thematic Mapper Plus (ETM+), Multi Spectral Scanner (MSS) and SPOT this paper analyzed the landscape change in Shenzhen Special Economic Zone of Guangdong Province, South China in 1979-2003, aimed to study the temporal-spatial landscape change characteristics, their causes, and major driving forces in this zone. The results revealed that the characteristic of landscape change were completely different among test three periods (1979-1990, 1990-2000 and 2000-2003). During the first period (1979-1990), urbanization developed very rapidly, and the natural vegetations mainly in Futian, Luohu and Yantian districts degraded and transformed into a landscape with anthropogenic components. In the second period (1990-2000), landscape conversion mainly took place in Nanshan and Futian districts, where various types of landscape were transformed into impervious surfaces, and parts of the vegetations were transformed into anthropogenic landscapes. During this period, typical urban characteristics were formed, whereas the remaining vegetations, especially forest stand, were little disturbed. In the third period (2000-2003), subtle consolidation was observed, and the use of pervious material in certain areas counteracted the adverse ecological impacts of urbanization. The extent of urbanization still increased, but the intensity of landscape change was at lower level than that in previous periods.
利用包括专题绘图仪（TM）、增强型专题绘图仪Plus（ETM+）、多光谱扫描仪（MSS）和SPOT数据在内的4个时期的卫星图像，分析了中国南方广东省深圳经济特区1979 - 2003年的景观变化，旨在研究该区域景观变化的时空特征、成因及主要驱动力。结果表明，在三个测试时期（1979 - 1990年、1990 - 2000年和2000 - 2003年）景观变化特征完全不同。在第一个时期（1979 - 1990年），城市化发展非常迅速，主要位于福田、罗湖和盐田区的自然植被退化并转变为人为景观。在第二个时期（1990 - 2000年），景观转换主要发生在南山和福田区，各类景观转变为不透水表面，部分植被转变为人为景观。在此期间，形成了典型的城市特征，而其余植被，尤其是林分，受干扰较小。在第三个时期（2000 - 2003年），观察到有细微的巩固，某些区域使用透水材料抵消了城市化的不利生态影响。城市化程度仍在增加，但景观变化强度低于前几个时期。
