摘要

摘要: 论文首先通过资源卫星遥感资料的解译,发现1986年至2010年间位于广东湛江南部东海岛在25年中由于围垦等人为活动使岛的土地面积增加了576.71hm²,同时岛上地物覆盖类型也发现了很大变化;土地利用的显著改观,引起该岛生态系统服务功能的显著变化.为此,本文采用Costanza生态系统服务价值计算方法得到单位面积的服务价值来定量的分析海岛生态系统服务功能的变化.研究发现在1986-20010年间,特别近年来,由于该岛大力发展石化、钢铁和港口产业的人为活动,使该岛的居民点和工交建设用地、水体和湿地面积增加,而耕地、林地、草地和荒漠面积则不同程度地减少,引起了东海岛的生态系统服务价值由1986年的547.57×10⁶元/年减少到2010年的493.94×10⁶元/年,生态服务功能的空间分布上则呈现西高东低的特征.研究结果表明通过基于遥感资料的海岛生态系统服务价值评价来定量化的分析海岛生态系统服务功能的变化为相关生态补偿服务等很有意义.

Abstract: Based on the interpretation of the remote sensing data presented by the resource satellite, this paper states the fact that the land-use area in Donghai Island, which is located in the south of Zhanjiang, Guangdong Province, had expanded by 576.71 hm² in the 25 years from 1986 to 2010 because of human activities such as land reclamation; in the meantime, great changes in types of land cover on the island have occurred. The definite change in land use leads to the remarkable transition in its ecosystem service value. Therefore, by applying the Costanza method in this paper to quantificationally analyze the changes in its ecosystem services on this island; the Costanza method is a calculation technique that shows the service value per unit area of island. It is found that from 1986 to 2010, especially in the recent years, due to the rapid development in the petrifaction, steel and port industries, the areas of cultivated land, woodland, grassland and desert have decreased in different degrees, while the lands for residence, industry and traffic construction and the areas of water and wetlands have increased. Consequently, compared with the number of RMB 547.57×10⁶ yuan per year in 1986, the ecosystem service value of Donghai Island was greatly reduced to RMB 493.94×10⁶ yuan per year in 2010. As for the spatial distribution, it presents a feature that it is higher in the west and low in the east. The results manifest that it is of great significance to analyze the changes in the ecosystem service function on the basis of the service value of the island presented by the remote sensing data in a quantificational way, which will contribute to the promotion of ecological compensation.
