| 摘 要： | 利用1986年和2000年遥感影像作为基本信息源，在RS和GIS技术的支持下，建立湿地空间数据库。运用景观生态学原理，选取反应景观空间结构和景观异质性的指数，对九龙江河口湿地景观空间格局的变化情况及其驱动力进行了分析。结果显示，1986-2000年，湿地景观发生子较大变化，人为因子是九龙江河口湿地景观变化的直接驱动力，自然因子以不同强度和方式影响湿地景观的演化。

| Abstract: | Based on remote sensing data from 1986 to 2000 as basic information resource and with the support of RS and GIS technologies, a wetland spatial information database was built up. According to the theory of landscape ecology, an index reflecting landscape spatial structure and landscape heterogeneity was used to study the changes of spatial patterns of landscape in the estuary wetland of Jiulong River. Results showed that there was a big change in wetland landscape pattern from 1986 to 2000 and that the human activities was the main and direct driving force of the changes while the natural factors have influenced the wetland evolution in different ways and different intensities. |
