The quantittive classfication and spatial distribution patttern of life form spectra of the plants in major chinese forest communities
中国主要森林群落植物生活型谱的数量分类及空间分布格局的研究

Adopting the C Raunkiaer life form classification system,and processed the database of plant life form spectra in major Chinese forest communities The plant life form spectra at the national scale were made and they were classified by using the aggregation analysis Applying modern information processing technics such as the GREEN and IDRISI etc,the eco climatic feasible parameter range of different life form spectrum were determined The geographical spatial distribution patterns were simulated and showed in maps The plant life form spectra in major forest communities in China were classified into 11 types,in which 3 were single samples Each plant life form spectrum has its characteristic compositions Computer simulation clearly showed the distribution patterns of major plant life form spectra in different vegetation regions in China The results afford important quantitative references for further research on the community characteristics and classification of forests in China
