摘　　要：选取大连市旅顺口区为研究区域,结合使用RS与GIS,采用1985、1990、1995、2000、2005、2010、2015年的Landsat…30m分辨率遥感图像,利用NDVI值并结合使用监督分类与Kappa检验,对旅顺口区植被覆盖情况进行研究。在此基础上进行统计分析,描述研究区域植被指数的年际变化特点,最终得出近30年来旅顺口区植被变化情况,通过植被变化的情况,为后期研究旅顺口区植被变化原因提供依据与定量基础。结果表明:由于旅顺口区近年来城市建设脚步加快,植被覆盖情况最高出现在1985年,最低在2015年,1985~2015年林地面积逐渐减少,这30年来林地减少了3.44%,植被破坏情况严重,林地面积变化巨大。Lvshunkou District of Dalian has been selected as the study area. This paper mainly studies the situations of the vegetation coverage in the study area. In combination with RS and GIS, the Landsat 30m resolution remote sensing images for the years of 1985, 1990, 1995, 2000, 2005, 2010 and 2015 are adopted. Using the NDVI value, Supervised Classification and Kappa testing, the vegetation coverage situations in the Lvshunkou District of Dalian have been studied. Based on the above, the statistical analysis is conducted. The inter-annual changes characteristics in NDVI in the study area have been described. Finally, the changes in vegetation in Lvshunkou District of Dalian in the past 30 years have been obtained, which will provide the basis for analyzing the reasons for the change in vegetation in the study area in later time and quantitative foundation. The results have shown that in recent years, with the acceleration of the urban construction in the study area, the best situations of vegetation coverage in the same area occurred in 1985, and the worst in 2015, the forest area has gradually diminished from 1985 to 2015 with a total decrease of 3.44% for the 30-year period. The vegetation has been damaged seriously and the forest area has been changed significantly.
