摘要
本文以系统理论为指导，以生态经济学原理为基础，根据中国油桐产区地域分异的自然特点，采用以定性为主，定性与定量相结合的原则，依据气候、大地形、小地形综合分析逐级控制的方法，划分出３个立地大区，１３个立地小区，４１个立地类型组，７２个立地类型四级立地分类评价系统。并从立地质量多用途角度来评价油桐产量及其发展适宜度、林地效益。
This paper is
concerned with the establishment of a 4-categorysystem of site classification and evaluation
devoted to tung oil tree,Vernicia fordii. The four categories comprise 3 site regions, 13
sitedistricts districts, 41 site type groups and 72 site types,assignedaccording to thestepwise
controlling factors of climate, macrotopographyand microtopography. The site quality is
assessed in terms of the tungyield from thestandpoint of multiple use of the site, suitability of
tungdevelopment, and integrated benefit of tung stands. The classificationand evaluationare
based on the systems theory, the principles of ecolon-omics, and thenatural law of geographic
differentiation of site regions.Qualitative analysis is emphasized while a combination of
qualitativeanalysis and quantitative assessment is applied.
