项目摘要

Prediction of various plant communities based on ecological traits of local flora has been important research theme for ecology. The results of such prediction should be applied for the assessments of invasion risk of new sepsis prior to introduction, and plant communities after global warming may also be predicted.Computer simulation have been major methods for such researches, however, technique to develop reliable model and to obtain feasible parameters have not yet establishes. Recently, statistical models to predict plant community have been developed since 1990s using data-mining technique. The author also started such works since early 1990s, and predicted dominance and composition of climax forests successfully (Koike 2001).As the results of this research project,1.In the Weed Risk Assessment for Ogasawara Islands, biological traits did not contributed the prediction of invasion effectively. The assumed target of invasion (wide area with various communities) may not suitable, and the target should be individual community.2.Plant species occurring a community have similar ecological traits. Thus, various plant communities have only a single functional trait. In application, we can use simple prediction model as a logistic regression.3.Based on the previously available data in warm-temperate zone in central Honshu (upper limit of warm-temperate zone), and new data corrected in this project in the warmest end of warm-temperate zone (close to subtropical) and northern end of cool temperate zone (close to boreal mixed forest zone), Climax forests have generally the similar assembly rule. Shade tolerance and tall maximum height was the key traits. Shade intolerance (probably high RGR) was the key for herbaceous communities. Community assembly rule for planted forests differ by climate zones probably by management methods of people.

根据当地植物群的生态学特征预测不同植物群落是生态学的重要研究课题。预测结果可应用于新败血症传入前的入侵风险评估，以及全球变暖后的植物群落预测，计算机模拟已成为此类研究的主要方法，但建立可靠模型和获取可行参数的技术尚未建立。自20世纪90年代以来，利用数据挖掘技术建立了植物群落预测的统计模型。作者从20世纪90年代初就开始了这方面的工作，并成功地预测了顶极森林的优势度和组成（Koike 2001）。假设的入侵目标（大面积的不同群落）可能并不合适，入侵目标应该是单个群落。2.同一群落内的植物物种具有相似的生态学特性。因此，各种植物群落只有一个功能性状。在实际应用中，可以采用简单的Logistic回归模型进行预测（暖温带上限），以及本项目在暖温带最暖端修正的新资料（接近亚热带）和冷温带的北方端（接近北方混交林），顶极林一般具有相似的聚集规律。耐荫性和株高是主要性状。耐荫性（可能是高RGR）是草本植物群落的关键。人工林的群落聚集规则因气候带而异，可能与人们的管理方式有关。
