连云港市花果山森林植被景观结构研究

Study on the Forest Vegetation Landscape in Huaguoshan of Lianyungang

以10 cm航空影像为数据源,以森林资源二类调查为基础,对连云港市花果山的森林植被景观结构进行分析。结果表明,研究区内麻栎树面积最大,分布最广泛;麻栎和松树是主要优势树种,乔木总面积占到研究区植被面积比例的70.75%,研究区植被结构较好。竹林(以金镶玉竹为主)和茶树是研究区内数量较多、分布较广且有区域特色的灌木;除2种主要灌木外,研究区还有大量混合生长的其他灌木,其面积总量和分布范围都仅次于麻栎树。研究区森林景观多样性指数较低,某些树种,如麻栎,景观优势度较大。森林景观以人工林为主,各种树种随机分布,形状受人工干扰较多。

With 10cm aerial images as the basic data,the forest vegetation landscape structure in Huaguoshan of Lianyungang was analyzed based on the second class survey of forest resources.As indicated by the results,sawtooth oak was the largest and most widely distributed tree species in the study area;sawtooth oaks and pine were the dominance tree species,about 70.75% of the study area was covered by arbor,the vegetation structure was good.Bamboo（dominated by Phyllostachys odoratum）and tea trees were the main shrubs with regional characteristics;apart from these two shrubs,there were also other mixed shrubs whose distribution area and quantity were second to sawtooth oaks.The landscape diversity index of the study area was low,such species as sawtooth oaks had large landscape dominance.The predominant landscape was dominated by man-made forest,and the location of each tree was more random and shaped by artificial interference.
