流域植被配置技术在新罗区拱桥溪植被空间优化中的应用

Application of Watershed Vegetation Allocation Technology in the Optimization of Vegetation Space in Gongqiao Stream in Xinluo District

鉴于新罗区拱桥溪植被空间规划不够合理以及存在大面积低效林等现状,开展流域植被配置技术在新罗区拱桥溪植被空间优化中的应用研究。划分拱桥溪植被空间优化范围,实地调查与遥感资料相结合,规划空间优化布局。植物种类筛选与配置,通过杉木、枫香、木荷等树种组合不同的植物群落。建设水土保持生态林,抚育管理苗木幼林,保证造林成活率。改造低效林优化植被空间,突出群落空间景观休闲功能。应用效果分析表明,本文方法将林草植被覆盖率从原来的88.2%提高至89.4%,研究区域内产水量总量有所减少,水源涵养功能有所提高,表明优化后的植被结构空间更为合理,本文方法具有可行性。

Due to the unreasonable vegetation space planning of Gongqiao stream in Xinluo district and the existence of large areas of low-efficiency forests,the application of basin vegetation allocation technology in the optimization of vegetation space of Gongqiao stream in Xinluo district was studied.Divide the optimal range of vegetation space in Gongqiao stream,and combine on-thespot investigation and remote sensing data to plan the optimal layout of space.Plant species selection and configuration,through the combination of Chinese fir,liquidambar,wood lotus and other tree species to combine different plant communities.Build soil and water conservation ecological forests,tend and manage seedlings and young forests to ensure the survival rate of afforestation.Renovate low-efficiency forests to optimize vegetation space,and highlight the leisure function of community space landscape.After the application effect analysis,the method in this paper increases the forest and grass vegetation coverage rate from the original 88.2%to 89.4%,the total water production in the study area is reduced,and the water conservation function is improved,which proves that the optimized vegetation structure space in this paper more reasonable,the method in this paper is feasible.
