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

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

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物生活型谱，并应用聚类分析方法，对植物生活型谱进行数量分类，在此基础上，应用生态信息系统（ Ｇ Ｒ Ｅ Ｅ Ｎ）和地理信息系统（ Ｉ Ｄ Ｒ Ｉ Ｓ Ｉ）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，将我国主要森林群落的植物生活型谱划分了１１ 种类型，其中 ３ 类为单独存在的样本。每一类植物生活型谱都有明显的组成特征。计算机模拟的结果清晰地展示了我国主要植物生活型谱类型在各植被区域的分布格局，为深入研究我国森林的群落学特征和群落分类提供了定量参考依据。

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
