试论建立我国森林立地分类系统 总被引：5，自引：0，他引：5
森林立地分类、评价及其应用,是造林营林工作的科学基础。建立全国森林立地分类系统就包含了“立地区划”的任务,森林立地分类单位就是立地区划单位。本文阐述了立地分类的原则和分类系统单位,并提出了我国包含3个立地区域、17个立地带、58个立地区和163个立地亚区的森林立地分类系统方案。 相似文献

The intensive nature of management practices in the exotic monoculture plantations of South Africa requires reliable decision support systems. Recent socio-economic developments, the need for optimal forest productivity, as well as increasing awareness of broader ecosystem values and environmental risks, highlight the importance of a unified approach to forest site classification and evaluation. This paper highlights the value of specific soil characteristics and its application value for a range of silviculture and management aspects related to site-specific forestry. A limited set of six soil variables are proposed for ecological mapping of forest landscapes at high-resolution operational-level scales. The variables proposed are parent material, soil classification, effective soil depth, depth limiting material, topsoil organic matter and topsoil texture. Each variable is discussed in terms of its significance as well as relevance to plantation forestry in South Africa. Shortcomings in our knowledge base and research requirements are highlighted, and the format of incorporation into a national forest site classification system is proposed. This paper will contribute to unity of purpose and understanding of forest site classification and evaluation in South Africa, and will promote management frameworks and decision support systems with desired environmental, economic and social benefits. 相似文献

Land for protective forest on the coast has special site conditions,and siteclassification is the scientific basis for seaboard afforestation.The site classification systemon the coast zone and islands of China may be classified into five levels-site region(sub-region),district,class,group,and type.The land division for afforestation is carried outby the principle of enviornmental heterogeneity among regions,sub-region and district onlarge scale,according to the difference of air temperature,moisture and type of coastgeomorphy.It may be classified into 7 regions,12 sub-regions and 55 districts.Themedium and small scaled division for site class,group and type,subdivided in a sitedistrict,are based on medium topography,topographic climate,micro-relief and soil conditions. 相似文献

高保护价值森林概念自提出以来受到了广泛的关注与研究,并在我国森林可持续经营体系中得到认可和应用。文中从高保护价值森林和公益林两者所涉及概念的范围、特征和经营原则3个方面进行了全面系统的分析比较。认为在范围上,两者关注层面和对象有所区别;在特征上,两者的推动者和补偿者截然不同;在经营原则上,两者可以互为补充。通过对高保护价值森林和公益林概念与经营原则的比较研究,肯定了高保护价值森林概念对于完善我国公益林经营管理模式的意义,对于我国创新经营发展思路、提高经营水平具有一定的指导意义和较高的参考价值,并在其两者之间探索了一条相互融通的渠道。 相似文献
