摘要
植树造林指的是在一定区域内的国土空间中进行人工绿化植栽的手段,其主要目的是达到修复生态系统,遏制极端天气及水土流失等次生灾害对人类生产生活的影响,其直接诱因是源自于人为过度开垦及无节制资源索取而形成的。植树造林的树种选择需结合修复用地的气候、区位、降雨量及生态独特性而展开,简单来说,就是尽可能地模拟原有植被状况,以乡土树种为核心,结合人们生产经济生产活动来合理地选择绿化树种,并搭配科学有效的栽植方式,实现乔灌草的合理配置,提升绿化造林的效率,进而提升林地生产力。因此,对山西地区的造林绿化工程来说,研究与分析不同区域的原始植被类型及当下待建林区的经济生产活动则显得尤为重要。只有理清了林地类型,树立典型的林地建设模式,明确森林立地分类,才能实现对山西不同地区绿化欠缺区域的“精准扶贫”。以黄河流域山西段的植树造林为研究对象,通过黄河流域山西段的植树造林的基础分析,对其植树策略以及存在的问题及措施进行论述。
Afforestation refers to the artificial planting of trees in a certain area of land space.Its main purpose is to restore the ecosystem and curb the impact of secondary disasters such as extreme weather and soil erosion on human production and life.The direct cause is man-made excessive reclamation and unrestrained demand for resources.The selection of tree species should be carried out in accordance with the local climate,location,rainfall and ecological uniqueness.Simulate the original vegetation status as much as possible,with native tree species as the core,rationally choose greening tree species,and use scientific and effective planting methods to realize the reasonable allocation of trees,shrubs and grass,improve the efficiency of greening and afforestation,and thus increase the productivity of forest land.Therefore,it is particularly important to study and analyze the original vegetation types in different regions and the economic production activities in the current forest areas to be built.Only by clarifying the types of forest land and establishing a typical construction model can we achieve“precise poverty alleviation”in areas lacking greenery in Shanxi Province.Taking afforestation in Shanxi section of Yellow River basin as the research object,the tree planting strategy,existing problems and solutions are discussed.
