Some researchers believe that the latter area possesses savanna vegetation. Savannas are closely associated with seasonal drought, and they may be defined by climatic climax vegetation in tropical and subtropical areas. Based on the ecoclimatic analyses as well as the surviving vegetation in Taiwan, we inferred that the potential natural vegetations of these 2 semi-arid regions were not savanna but forest with some drought-deciduous trees. In conclusion, the physiognomic type of grassland dotted with trees may occur in small areas at present, but Taiwan lacks climate-shaped savanna climax vegetation.

本研究将疏林定义为分布於热带及亚热带之气候形塑的极相植群,气候分析结果表明台湾半乾旱区域之缺水逆境并不严重,再配合现生残存植群之观察,发现台湾有形相为疏林的现生局部性植群,但其潜在自然植群应为参杂有乾旱落叶之阔叶树种的森林,并不存在较大面积之潜在的气候型极相疏林。

For organizing vegetation submodel, started with the bottom-up gateway to agglomerate plot-data. The vegetation types must be confirmed before predictive vegetation mapping, therefore designed a transforming program to combine 585 plot-data from different surveys for the purpose. But the result of the classification and ordination of the combined plot-data couldn't display comprehensive vegetation types of Taiwan, because the plots were insufficient and disproportionate. Consequently, this study adopted the top-down gateway to divisive vegetation. After referring to Taiwan and east-Asia vegetation research papers and American national vegetation classification system etc., the physiognomic classification scheme of Taiwan had been drafted as vegetation submodel. The scheme included 4 levels: 2 classes, 5subclasses (subarctic, coldtemperate, cooltemperate, warmtemperate, subtropical), 8 groups (based on phenology and types of predominant leaf) and 16 formations (based on moisture regime and predominant taxa). And, the scheme dealt completely with the diverse nomenclatures of vegetation types in the past.

为建立植群亚模型,首先依「整合大量样区资料,由下而上的低阶植相聚类」之途径,设计建档程序及转档程式,成功整并不同来源之585个样区资料,但因样区数目不足且分布不均,分析结果未能显示出台湾完整的植群类型;故转循「预先设定植群类型,由上而下的高阶形相分类」之途径,经参考他国植群分类系统及台湾、东亚植群分类研究报告,订定分类原则及架构,提出4阶层之潜在植群形相分类方案:(1)寒原、森林2类群系纲;(2)亚寒带、冷温带、凉温带、暖温带、亚热带5类群系亚纲;(3) 8类群系组表徵优势植群之叶片的物候与形态;(4) 16类群系说明其水分境制及优势分类群;此方案统一处理了过去各种有关植群划分之纷岐名制,方案之各阶植群类型亦即本研究之植群亚模型。

During the Last Interglaciation it was the forest, mainly composed of broadleaves, or forest-grassland at the east and middle part of the Chinese Loess Plateau, and was the forest-grassland at the west part of the Chinese Loess Plateau. It changed to the forest or forest-grassland at the most part of the Chinese Loess Plateau in the Holocene, some kinds of hardwood broadleaves dispersing at the warm temperate and the tropic zones appeared. Now the vegetation at the Chinese Loess Plateau inherits from that during the Holocene, the vegetation have been heavily destroyed owing to the human being actions. The vegetation protection at the Chinese Loess Plateau is a significant problem.

末次间冰期期间气候温暖湿润,黄土高原的中、东部地区主要发育了以落叶阔叶林为主的森林或森林草原植被,黄土高原西部地区主要发育的是以针叶林为主森林草原植被;全新世期间黄土高原的植被状况发生较大变化,黄土高原的大部分地区为森林植被或森林草原植被,植被中还有暖温带落叶阔叶林,并含有少量亚热带种属;现代黄土高原的植被主要还是继承了全新世以来的植被状况,但是由于人类活动的加剧,对黄土高原的植被产生了毁灭性的破坏,因此,如何保护黄土高原的自然植被是我们面临的一个严峻的现实问题。
