【摘要】 以北京八达岭林场内残长城风景林为研究区域,探索改善该风景林季节性景观质量的经营措施。根据研究区地理特点提出了划分该区域风景林的方法。依托GIS作为平台,划分出研究区风景林范围及类型(灌木型风景林、阔叶林型风景林和针阔混交林型风景林)。选取色彩丰富度和色彩均匀度作为经营指标,经计算得到灌木型风景林、阔叶林型风景林和针阔混交林型风景林的色彩丰富度指数分别为0.38、0.24和0;色彩均匀度指数分别为0.64、0.26和0。对灌木型风景林以封育措施为主;阔叶林型风景林和针阔混交型风景林的经营措施以抚育间伐为主,合理选择树种提高风景林景观美景度的同时稳定林分结构。更多还原

【Abstract】 The scenery forests neighboring the remnant Great Wall in Beijing Badaling Forest Farm were taken as the research areas to probe management measures to improve the quality of seasonal scenery in this region.Scenery forests were divided into different types based on the geographic characters of the study area and GIS: shrubbery,broad-leaved,and conifer-broadleaves scenery forests.Color richness and color equitability were used as management indices.After calculation,color richness and color equitability indices of three different types of scenery forest were 0.38 and 0.64(shrubbery forest),0.24 and 0.26(broad-leaved forest),and 0 and 0(conifer-broadleaves scenery forest) respectively.It was concluded that enclosure management should be adopted mainly in shrubbery scenery forests,tendering thinning for broad-leaved and coniferous-broad-leaved scenery forests.In addition,reasonable selection of the tree species could promote scenic beauty the forests while stabilizing their stand structures in the study area.更多还原
