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

采用Ｃ．Ｒａｕｎｋｉａｅｒ的生活型分类系统，对我国主要森林群落的生活谱资料进行整理，编制了全国划分标准统一的植被生活型谱，并应用聚类分析方法，对植物生活型谱进行数量分类，在此基础生态信息系统（ＧＲＥＥＮ）和地理信息系统（ＩＤＲＩＳＩ）等现代信息处理技术，定义各谱系的生态气候适应参数区间，模拟并图象显示各类植物生活型谱在地理空间上的分布格局，通过聚类分析，将我国主要木 落的植物生活型谱划分了１１种类

The quantittive classfication and spatial distribution patttern of life form spectra of the plants in major chinese forest communities

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
