摘　　要：在生态遥感解译矢量数据基础上,采用公里格网、土地利用转移矩阵及生态景观指数方法分析了2005~2009年大连市土地利用变化及生态景观格局的动态变化特征,结果表明:大连市沿海城镇建设用地扩张明显,林地向耕地、农田向果园和水产养殖转化等土地类型转变较为突出,耕地、林地和建设用地占据景观格局绝对优势,土地利用斑块形状主要取决于自然地貌与自然环境条件,建设用地不规则扩张影响景观破碎化程度增加及连接性下降。Based on the vector data of ecological remote sensing interpretation,this paper analyzes the dynamic characteristics of land use change and ecological landscape pattern in Dalian from 2005to 2009by using the methods of kilometer grid,land use transfer matrix and ecological landscape index.The results show that the construction land in Dalian coastal cities and towns expands obviously.and the forest land transforms to the cultivated Land.Farmland to orchard and aquaculture is more prominent.The landscape pattern is dominated by cultivated land,forest land and construction land.The patch shape of land use mainly depends on the natural landform and natural environment conditions.The irregular expansion of construction land affects the increase of landscape fragmentation and the decrease of connectivity.
