营口南部海岸景观格局及土地利用时空变化分析

为明确1990—2015年营口南部海岸景观格局和土地利用的时空变化,采用景观生态学的方法,结合地理信息系统空间分析和统计功能进行定量研究。结果表明:2005年为明显的过渡时期,在此之前营口南部海岸生态过程稳定,景观边界形状的复杂度和破碎度变化不大,土地利用方式及面积变化相对较小;2005年以后,生态过程活跃度有所下降且不再处于稳定状态,由于受到人类生产活动的干预,土地利用方式和面积也发生了巨大的变化,从原先的盐田-养殖池塘景观转变为盐田-养殖池塘-工业城镇的复合式景观。

Spatio-et mporal Variation of Land Use and Landscape Pattern inS outh Coas t of Yingkou

In order to define spatio -temporal variation of land use and landscape pattern in south coast of Yingkou during 1990 -2015,the functionof spatial analysis and statistical in GIS and method of landscape ecology were used to quantitatively study.The results showed that 2005 asthe obvious transition period, the ecological processes was stable before 2005,complexity and fragmentation of landscape boundary shape changewas small, the land use mode and area change was relatively small;since 2005, the ecological process has declined and was no longer in stablecondition, the land use mode and the area have changed greatly due to the interference of human activities.From the original salina -breed pondlandscape, it was transformed into a compound landscape in the salina -breed pond -industrial towns.
