英文摘要In order to explore the spatiotemporal characteristics and causes of tidal flat wetland in Jiaozhou Bay,we firstly extracted the LUCC information of the surrounding area of Jiaozhou Bay from remote sensing images from 1987 to 2017 by means of object-oriented classification,and at the same time used the tidal calibration model to correct the bare tidal flats in the land use types to obtain the real tidal flat wetland spatial scale.Then,we analyzed the LUCC characteristics of the surrounding area of Jiaozhou Bay from 1987 to 2017 and the spatiotemporal characteristics of the tidal flat wetland in Jiaozhou Bay,and the causes of the spatiotemporal characteristics of the tidal flat wetland in Jiaozhou Bay from 1987 to 2017 from the perspective of LUCC.The results showed that:(1)cultivated land,build-up areas and forest areas are the main land-use types of study area;cultivated land decreased and built-up areas increased while forest areas decreased firstly and then increased during study period;(2)the area of tidal flat wetland decreased and the decreasing rate slowed down gradually;while the upper bounds of tidal flat wetland tended to move towards the inside of Jiaozhou Bay;(3)the reclamation activity of sea was the main reason for the changes of tidal flat wetland;build-up areas,grass land,bareland and inland water were the main land-use types after reclamation activity of sea.To sum up,the upper bounds of tidal flat wetland in Jiaozhou Bay pushed towards the sea year by year,and the area gradually reduced.The reduced part of tidal flat wetland was mainly transformed into build-up areas,grassland,bare land and inland waters,which was mainly caused by reclamation activity of sea.
中文摘要为了探究胶州湾潮滩湿地的时空特征及其成因,首先通过面向对象分类的方法从遥感影像中提取胶州湾周边地区19872017年的土地利用变化信息,同时利用潮位校正模型对土地利用类型中的裸潮滩进行校正以获得真正的潮滩湿地空间范围。随后分析了胶州湾周边地区19872017年的土地利用变化特征以及胶州湾潮滩湿地的时空特征,并从土地利用变化方面分析了胶州湾19872017年潮滩湿地时空特征的成因。结果表明:(1)胶州湾周边的土地利用类型以耕地、建设用地以及林地为主,且近30年的耕地面积逐渐减少,建设用地面积逐渐增加,林地面积先减少后增加,其他土地利用类型呈现无规律的变化;(2)潮滩湿地在30年间不断减少,减少速度逐渐减慢,而潮滩湿地的上边界随着时间的推移不断向胶州湾内部推进;(3)围填海活动是胶州湾潮滩湿地变化的主要成因,建设用地、草地、裸地以及内陆水域是围填海之后的主要土地利用方式。综上,胶州湾潮滩湿地上边界逐年向海推进,面积逐渐减少,潮滩湿地所减少的部分主要转变为建设用地、草地、裸地以及内陆水域,这主要由围填海活动所致。
