内容:本文利用1991年和2005年的TM遥感影像作为基本信息源,运用景观生态学原理,选取景观格局指数,利用FRAGSTATS 3.3分析和研究区域内景观格局的动态变化及其驱动力.研究结果表明,1991年-2005年杭州湾南岸地区研究区内景观格局变化比较剧烈,期间建设用地呈现大幅度增长趋势,而滩涂和林地等则呈现出减少的趋势,景观破碎度增加,均匀度减小.人类活动对景观类型分布的干扰强度不断增大,使得各景观类型在研究区内的分布更为广泛.人口增加、经济发展、气候和水文因素等是杭州湾南岸地区景观格局演变的主要驱动力.最后通过对区域大气环境、水环境以及生物多样性的研究,可以看到这种景观格局的变化对研究区的生态效应是负面的.
In this paper,by using the TM remote sensing images in 1991 and 2005 as the basic information source,according to the theory of landscape ecology,landscape pattern index,dynamic variation of landscape pattern of 3.3 analysis and in the study area using FRAGSTATS and its driving force.The results show that,in 1991 the changes of landscape pattern in the study area south of Hangzhou Bay area -2005 is more intense,during the period of construction land increased greatly,while the mudflat and forestland,showing a decreasing trend,the landscape fragmentation increased,evenness decreased.The disturbance of human activities on landscape type distribution of intensity increases,the distribution of landscape types in the study area is more widely.The increase of population,economic development,climate and hydrological factors are the main driving force for the evolution of landscape pattern of Hangzhou Bay area.By the end of the atmospheric environment,water environment and biodiversity research,you can see the ecological effects of this change in landscape pattern of the study area is negative.
