摘　　要：为掌握建德市森林植被变化趋势,基于建德市2000年、2008年、2017年陆地影像数据和2017年森林资源调查数据,运用归一化植被指数(Normalized differential vegetation index,NDVI)、植被覆盖度和差值植被指数,分析了2000—2017年建德市市区及所属乡镇的森林植被变化规律。结果表明:建德市植被存量一直维持在较高水平,各乡镇的植被指数值保持在0.4以上,中高植被覆盖度区域达到82.63%;2000—2008年间,植被生长状况下降明显,但植被覆盖度降幅相对较小,植被变化表现为轻微下降,变化区域主要集中在主城区;2000—2017年间,植被生长状态下降趋缓,植被覆盖度降幅增大,植被变化依旧为轻微下降趋势,变化区域主要集中在乡镇建成区。人类活动是影响建德市植被变化的主要原因,在国家森林城市创建过程中,可重点加强建成区及人类活动频繁区域的绿化建设,为建德市国家森林城市创建提供科学依据和绿化方向。To grasp the change trend of forest vegetation in Jiande,based on land imagery data from 2000,2008,and 2017,as well as forest resource survey data from 2017,this study analyzed the variation pattern of forest vegetation across Jiande and its townships from 2000 to 2017 using normalized differential vegetation index(NDVI),vegetation cover percentage,and difference vegetation index.The results showed that the vegetation stock in Jiande has been maintained at a high level,the vegetation index value of each township remained above 0.4,and the areas with medium to high vegetation coverage reached 82.63%.During 2000—2008,the vegetation growth condition declined significantly,the vegetation coverage showed a decrease,and the change of vegetation showed a slight decrease,and the change area was mainly concentrated in the main urban area.Between 2000 and 2017,the decline in vegetation growth status slowed down,the decrease in vegetation cover increased,the vegetation performance remained a slight downward trend,and the change area was mainly concentrated in the township built-up areas.Human activities were the main reason affecting the change of vegetation in Jiande,and in the process of creating a national forest city,we can focus on strengthening the greening construction of built-up areas and regions with frequent human activities,so as to provide a scientific basis and greening direction for the creation of a national forest city in Jiande.
