摘要
采用GIS技术与数量生态分析技术(TWINSPAN)相结合的方法,对黄土高原植被进行数量区划。植被数量区划的结果表明:黄土高原可划分为4个植被区,包括5个植被亚区,与黄土高原植被DCA、CCA、DCCA排序的结果相吻合。
The vegetation individuals and attributes in Loess Plateau were classified by GIS technology and TWINSPAN (two-way indicator species analysis). Results showed that the Plateau was classified into four zones, including five sub-zones, which was in accordance with the results obtained by DCA (detrended correspondence analysis), CCA (canonical correspondence analysis) and DCCA.
