摘要:

填海造陆在增加土地资源的同时也对生态环境带来了深远的影响,对填海造陆的监测和研究成为现实需要。本文以1991年、1995年、2000 年的Landsat TM 影像数据,2005年SPOT卫星影像和2010年环境卫星HJ-1 CCD及2014年SPOT遥感影像数据为主要数据源,构建了基于元胞自动机模型(CA)的岸线提取方法,并对锦州湾附近海域的围填海分布、强度指数、质心坐标及其利用情况等方面进行深入分析。研究结果表明:①23年间锦州湾附近海域海岸线共增加了20.07km,在1991—1995年和2005—2010年两个时间段增加较快;②锦州湾中部北港镇、牛营子及西海口等地区海岸线位移量相对较大,围填海强度较高;③锦州湾新增围填海面积50.67 km2,城市建设、港口用海及围海养殖用海为围填海的主要类型,盐业用海面积相对减小,未利用类型面积增加;④锦州湾围填海重心总体往东北方向偏移。

Abstract:

Reclamation not only increases the land resources, but also has a profound impact on the ecological environment. It is essential to monitor the land reclamation. Based on Landsat TM image data in 1991, 1995 and 2000, SPOT satellite image in 2005, HJ-1 CCD in 2010 and SPOT remote sensing image data in 2014, a method of shoreline extraction based on CA was constructed. The reclamation distribution, intensity index, centroid coordinates and their utilization in the sea area near Jinzhou bay were analyzed in depth. The research results show that: (1) The coastline near Jinzhou bay has increased by 20.07 km for last 23 years, in particular between 1991—1995 and 2005—2010; (2) The displacement of coastline in Beigang town, Niuyingzi and west Haikou in the central part of Jinzhou bay is relatively large, and the reclamation intensity is relatively high; (3) The newly increased reclamation area in Jinzhou bay is 50.67 km2, and its utilization type is mainly urban construction. The area of port construction and reclamation has steadily increased, the area of salt industry is reduced, and the proportion of unused land is increasing year by year; (4) The center of gravity of the reclamation in Jinzhou Bay is generally shifted to the northeast, with the sea near the west of Haikou as the center. A large number of new port construction site was created. Therefore, we should strengthen the ecological transformation and protection of the shoreline that has been filled, standardize the human development activities, reduce the ecosystem pressure in the coastal zone of this region, and further carry out the ecological environment assessment of the gulf at the same time to provide theoretical guidance and scientific basis for the sustainable development of the region.
