青岛市生态空间遥感监测与评价

从生态空间的监管需求出发,利用高分辨率卫星数据获取不同生态系统类型的分布状况,分析2012—2017年青岛市生态空间的演变格局,从水源涵养、水土保持、生物多样性维护3个方面评价青岛市生态空间的服务功能变化情况。结果表明:2012—2017年,青岛市生态空间的生态系统结构变化明显,主要表现为森林和城镇面积显著增加,草地、农田、裸地及海洋面积明显减少;水源涵养、水土保持、生物多样性维护功能的生态状况指数的增长率分别为2.63%、0.36%、2.55%,说明生态空间的生态系统服务功能得到提升,生态状况总体呈变好趋势。

Monitoring and Evaluation of Eco-space in Qingdao City Based on Remote Sensing

In order to meet the need of environmental supervision of eco-space, the distributions of ecosystem types in Qingdao were extracted from high-resolution satellite data, and the evolvement of pattern from 2012 to 2017 was analyzed. The changing ecological functions of eco-space were then analyzed from the aspects of water conservation, soil and water conservation and biodiversity conservation, respectively. The results showed that the ecosystem structure of eco-space changed significantly from 2012 to 2017, which was mainly reflected in the significant increase of forest and urban, and the obvious decrease of grassland, farmland, bare land and marine ecosystem. However, the eco-condition index of water conservation, soil and water conservation and biodiversity conservation increased by 2.63%, 0.36% and 2.55%, respectively, indicating an improvement of ecosystem functions and services. In conclusion, the study indicates that the ecological situation of eco-space of Qingdao has been improved in recent years.
