【摘要】：森林的林内景观是森林景观的重要组成部分,也是森林游憩的主要场所,林内景观的评价对风景游憩林的经营管理具有重要的作用。本文在对大围山国家森林公园实际踏查的基础上,建立了 36块林内景观样地,调查了样地内的植物种类,观测了林内景观结构特征相关数据,采用SBE法对林内景观的质量进行评价,以期为公园的林内景观质量提升和合理建营提供了科学依据。研究表明,对林内景观美景度贡献最大的景观要素依次为:林下层统一度(30.6%)、枯树倒木(20.3%)、趣味性(14.2%)、枯落物(13.4%)、水平透视距离(8.7%)、草本高度(7.0%)、色彩丰富度(5.8%)。采用逐步线性回归法,构建了如下林内景观质量评价模型:SBE=40.661-39.581X6-2-48.041X6-3-16.735X7-2-11.518X7-3+20.608X8-2+11.953X8-3+23.349X9-2+27.476X9-3-10.409X9-4-15.338X10-2-31.811X10-3+72.540X11-1+2.434X11-2+13.746X15-2研究表明,研究区域的林内景观质量整体存在较大的提升空间,不同林分的美景度值在统计上有差异,景观质量由优至劣排列为阔叶林针叶林针阔混交林竹阔混交林竹林竹林。在建立评价模型的基础上,针对不同林分提出切实可行的林内景观改造方案,针叶林采取林间抚育、林下修枝、地被植物培育等措施,提高林下层统一度、减少视域内的枯落物和枯木倒树;阔叶林通过人工整枝、林间清理、林下地被补植与培育、林木更新改造等措施提高林下层统一度、减低草本高度和提高林内的趣味性;针阔混交林可以通过林间抚育、林下种植来提高趣味性;竹阔混交林的改造方案为林下清理、林间抚育和增加地被植物;竹林提高林内质量的的主要改造措施为林下清、抚育间伐和地被植物的培育。
[Abstract]:The forest landscape is an important part of the forest landscape and the main place for forest recreation. The evaluation of forest landscape plays an important role in the management and management of landscape recreation forest. Based on the actual investigation of the National Forest Park in Dawei Mountain, 36 plots of forest landscape were established, and the plant species in the sample land were investigated. The related data of forest landscape structure characteristics were observed, and the SBE method was used to evaluate the forest landscape quality in order to provide a scientific basis for the improvement of forest landscape quality and the reasonable construction and management of the park landscape. The landscape elements that contribute most to the landscape beauty of the forest are as follows: the degree of unification of the understory is 30.6, the degree of withered trees is 20.3, the interesting is 14.2cm, the litter is 13.4m, the horizontal perspective distance is 8.7, the height of herb is 7.0 and the richness of color is 5.8.The method of stepwise linear regression is used. The following forest landscape quality evaluation model: 1: SBEN 40.661-39.581X6-2-48.041X6-3-16.735X7-2-11.518X7-3 20.608X8-2 11.953X8-3 23.349X9-2 27.476X9-3-10.409X9-4-15.338X10-2-31.811X10-3 72.540X11-1 2.434X11-2 13.746X15-2 study shows that the landscape quality in the study area has a large space for improvement, and the beauty values of different forest stand are statistically different. The landscape quality was arranged from excellent to bad as broad-leaved coniferous mixed coniferous and broad-leaved mixed bamboo and broad-leaved mixed bamboo and bamboo forest. Based on the establishment of evaluation model, the feasible scheme of landscape transformation in different stands was put forward, and coniferous forest was farmed between forests. In order to improve the uniformity of the understory and reduce the litter and the fallen tree in the horizon, the broad-leaved forest is planted and cultivated by artificial pruning, clearing the forest, and replanting and cultivating the understory, such as pruning under the forest, cultivating the ground under the forest, and so on. Such measures as forest regeneration and transformation can improve the uniformity of the lower forest, reduce the height of herbs and increase the interest in the forest; coniferous and broad-leaved mixed forests can be nurtured between the forests and planted under the forest to enhance the interest; the transformation scheme of the bamboo and broad-leaved mixed forest is to clean up the forest undergrowth. The main measures to improve the quality of bamboo forest are forest clearing, thinning and cultivation of ground cover plants.
